All boards with DMI_PRODUCT_FAMILY="CBxx63" are Baytrail boards. We do produce 
other x86 boards but the family
is exclusive to Baytrail.
I might be misunderstanding how the matching works. Does this match anything 
other than CBxx63?

 .matches = {
 DMI_MATCH(DMI_SYS_VENDOR, "Beckhoff Automation"),
DMI_MATCH(DMI_PRODUCT_FAMILY, "CBxx63"),
},

I can switch it to DMI_EXACT_MATCH but even substring matching works.

Not an issue for these industrial PCs as sleep is an unusual use case.
Having no ethernet after boot/sleep is worse.

Sorry, I guess I should make this clearer in the message.
All boards with "CBxx63" are Baytrail.

DO NOT TAKE THIS FOR GRANTED!!!

[linux-kernel]

Goodday

I think you will not be happy, because I have a very bad news for 
you. Just a few months ago I hacked your operating system and I 
have full control of your device.

I implanted a small application into your device which sends me 
your current IP address and allows me to connect to your device 
just like remote desktop.

Even if you change your password, it won’t help.

How I infected you?
The router that you used to connect to Internet had a security 
hole.
You can read about this problem by searching for CVE-2018-10562.
I hacked your router and I put my code into it, and when you 
tried to connect to Internet, my program infected your device.

Later I made a full copy of your hard drive (I have all your 
email contact lists, list of websites you visited, phone numbers, 
your passwords etc.)


A little while later, when I was searching your web browsing 
history I was shocked by what I saw!! The sites for adults you 
are visiting... you know what I mean...

I just want to say - your fantasies are shifted far away from the 
normal course!...

For months I have been spying on you through your device camera.. 
especially when you visited those sites to have fun...Those 
videos show clearly you having fun and the content for adults you 
were watching.. this is pretty nasty and I would be very worried 
if I were you.

I have secured 2 videos:
linux-kernel@vger.kernel.org_1557074047.mp4 (119.1 MB)
linux-kernel@vger.kernel.org_1555285697.mp4 (64.5 MB)

You can verify that the timestamps correspond to the moments you 
were enjoying yourself...Now, because I do not like at all what I 
saw (that’s pretty crazy and ugly) I ask you to send me a 
donation through Bitcoin network. 2000 US dollars is a fair price 
(considering your perversions).

If you want me to forget about the whole case, remove the files 
and disable the nasty app that is spying you, send me the Bitcoin 
payment within 72 hours. Yes, I give you 72 hours only.

Here is my wallet:

===
Send exactly 0.291578 BTC to my address:
1JiE6YXy2rvZJfVb1E3JnSCdEjmgKqUkm5

(copy it and paste - it’s case sensitive)
===
0.291578 BTC = 2000 dollars

If you do not send me the Bitcoin, I promise you - I will send 
those 4 files with you enjoying yourself to all your contact 
lists, associates and social network friends.

I still have access to your device and I know when you read this 
message. When you opened it, time started ticking. You have 72 
hours only!

I am from Russia and nobody will help you if you report this 
email.. Before they find me your life will be ruined! If you do 
not cooperate with me - I will release this ugly material 
immediately.

This is why I advise you - send me the Bitcoin and let’s forget 
about the whole situation. I know you can afford it.

If you do not know how to send bitcoin

Step 1: Create an account on www.localbitcoins.com
Step 2: Buy 0.291578 BITCOIN
Step 3: Send the amount on this BTC address: 
1JiE6YXy2rvZJfVb1E3JnSCdEjmgKqUkm5
Step 4: Contact me on this email address chanblog...@aol.com
with this subject: 980VIPERMARVO-RESTOREKEYPC00765
After this steps you will receive through email the key and a
decrypt tutorial.

Here is another list where you can buy bitcoin: 
https://bitcoin.org/en/exchanges


Here is my address again:

===
Send exactly:

0.291578 BTC

to my address: 1JiE6YXy2rvZJfVb1E3JnSCdEjmgKqUkm5

===

Remember to send the exact amount as above! This way I will know 
it’s from you.

Do not be angry at me. This is just my job, and you are not the 
only person I caught.

Be angry at your fantasies - if you didn’t visit those sites for 
adults you would have no problem.. but now...

I am waiting for your bitcoin.

Remember, time is ticking..

[PATCH] platform/x86: pmc_atom: Add CB4063 Beckhoff Automation board to critclk_systems DMI table

[linux-kernel-dev]

From: Steffen Dirkwinkel 

The CB4063 board uses pmc_plt_clk* clocks for ethernet controllers. This
adds it to the critclk_systems DMI table so the clocks are marked as
CLK_CRITICAL and not turned off.

[PATCH 0/1] Add several Beckhoff Automation boards to critclk_systems DMI table

[linux-kernel-dev]

From: Steffen Dirkwinkel 

There are several Beckhoff Automation industrial PC boards which use
pmc_plt_clk* clocks for ethernet controllers. The patch adds affected boards
to critclk_systems DMI table so the clocks are marked as CLK_CRITICAL and
not turned off.
This should be applied on top of another patch as both change
the same table:

Hacking Alert! You account was hacked (your password:qwerty)

[linux-kernel]

Dear user of vger.kernel.org!

I am a spyware software developer.
Your account has been hacked by me in the summer of 2018.

I understand that it is hard to believe, but here is my evidence:
- I sent you this email from your account.
- Password from account linux-kernel@vger.kernel.org: qwerty (on moment of 
hack).

The hacking was carried out using a hardware vulnerability through which you 
went online (Cisco router, vulnerability CVE-2018-0296).

I went around the security system in the router, installed an exploit there.
When you went online, my exploit downloaded my malicious code (rootkit) to your 
device.
This is driver software, I constantly updated it, so your antivirus is silent 
all time.

Since then I have been following you (I can connect to your device via the VNC 
protocol).
That is, I can see absolutely everything that you do, view and download your 
files and any data to yourself.
I also have access to the camera on your device, and I periodically take photos 
and videos with you.

At the moment, I have harvested a solid dirt... on you...
I saved all your email and chats from your messangers. I also saved the entire 
history of the sites you visit.

I note that it is useless to change the passwords. My malware update passwords 
from your accounts every times.

I know what you like hard funs (adult sites).
Oh, yes .. I'm know your secret life, which you are hiding from everyone.
Oh my God, what are your like... I saw THIS ... Oh, you dirty naughty person 
... :)

I took photos and videos of your most passionate funs with adult content, and 
synchronized them in real time with the image of your camera.
Believe it turned out very high quality!

So, to the business!
I'm sure you don't want to show these files and visiting history to all your 
contacts.

Transfer $868 to my Bitcoin cryptocurrency wallet: 
1Bt4psBJmjfVTcW6eYiJZ6HEbpFgKkBSX4
Just copy and paste the wallet number when transferring.
If you do not know how to do this - ask Google.

My system automatically recognizes the translation.
As soon as the specified amount is received, all your data will be destroyed 
from my server, and the rootkit will be automatically removed from your system.
Do not worry, I really will delete everything, since I am working 
with many people who have fallen into your position.
You will only have to inform your provider about the vulnerabilities in the 
router so that other hackers will not use it.

Since opening this letter you have 48 hours.
If funds not will be received, after the specified time has elapsed, the disk 
of your device will be formatted,
and from my server will automatically send email and sms to all your contacts 
with compromising material.

I advise you to remain prudent and not engage in nonsense (all files on my 
server).

Good luck!

Change your password qwerty immediately. Your account has been hacked.

[linux-kernel]

I greet you!

I have bad news for you.
06/28/2018 - on this day I hacked your operating system and got full access to 
your account linux-kernel@vger.kernel.org
On that day your account (linux-kernel@vger.kernel.org) password was: qwerty

It is useless to change the password, my malware intercepts it every time.

How it was:
In the software of the router to which you were connected that day, there was a 
vulnerability.
I first hacked this router and placed my malicious code on it.
When you entered in the Internet, my trojan was installed on the operating 
system of your device.

After that, I made a full dump of your disk (I have all your address book, 
history of viewing sites, all files, phone numbers and addresses of all your 
contacts).

A month ago, I wanted to lock your device and ask for a small amount of money 
to unlock.
But I looked at the sites that you regularly visit, and came to the big delight 
of your favorite resources.
I'm talking about sites for adults.

I want to say - you are a big pervert. You have unbridled fantasy!

After that, an idea came to my mind.
I made a screenshot of the intimate website where you have fun (you know what 
it is about, right?).
After that, I took off your joys (using the camera of your device). It turned 
out beautifully, do not hesitate.

I am strongly belive that you would not like to show these pictures to your 
relatives, friends or colleagues.
I think $913 is a very small amount for my silence.
Besides, I spent a lot of time on you!

I accept money only in Bitcoins.
My BTC wallet: 15ZHnf1MPn6ybb8yUeAoCQ1AJtiKhg3NrP

You do not know how to replenish a Bitcoin wallet?
In any search engine write "how to send money to btc wallet".
It's easier than send money to a credit card!

For payment you have a little more than two days (exactly 50 hours).
Do not worry, the timer will start at the moment when you open this letter. 
Yes, yes .. it has already started!

After payment, my virus and dirty photos with you self-destruct automatically.
Narrative, if I do not receive the specified amount from you, then your device 
will be blocked, and all your contacts will receive a photos with your "joys".

I want you to be prudent.
- Do not try to find and destroy my virus! (All your data is already uploaded 
to a remote server)
- Do not try to contact me (this is not feasible, I sent you an email from your 
account)
- Various security services will not help you; formatting a disk or destroying 
a device will not help either, since your data is already on a remote server.

P.S. I guarantee you that I will not disturb you again after payment, as you 
are not my single victim.
 This is a hacker code of honor.

>From now on, I advise you to use good antiviruses and update them regularly 
>(several times a day)!

Don't be mad at me, everyone has their own work.
Farewell.

Change your password qwerty immediately. Your account has been hacked.

[linux-kernel]

I greet you!

I have bad news for you.
06/28/2018 - on this day I hacked your operating system and got full access to 
your account linux-kernel@vger.kernel.org
On that day your account (linux-kernel@vger.kernel.org) password was: qwerty

It is useless to change the password, my malware intercepts it every time.

How it was:
In the software of the router to which you were connected that day, there was a 
vulnerability.
I first hacked this router and placed my malicious code on it.
When you entered in the Internet, my trojan was installed on the operating 
system of your device.

After that, I made a full dump of your disk (I have all your address book, 
history of viewing sites, all files, phone numbers and addresses of all your 
contacts).

A month ago, I wanted to lock your device and ask for a small amount of money 
to unlock.
But I looked at the sites that you regularly visit, and came to the big delight 
of your favorite resources.
I'm talking about sites for adults.

I want to say - you are a big pervert. You have unbridled fantasy!

After that, an idea came to my mind.
I made a screenshot of the intimate website where you have fun (you know what 
it is about, right?).
After that, I took off your joys (using the camera of your device). It turned 
out beautifully, do not hesitate.

I am strongly belive that you would not like to show these pictures to your 
relatives, friends or colleagues.
I think $913 is a very small amount for my silence.
Besides, I spent a lot of time on you!

I accept money only in Bitcoins.

linux-kernel@vger.kernel.org has password qwerty. Password must be changed

[linux-kernel]

Hello!

I'm a programmer who cracked your email account and device about half year ago.
You entered a password on one of the insecure site you visited, and I catched 
it.
Your password from linux-kernel@vger.kernel.org on moment of crack: qwerty

Of course you can will change your password, or already made it.
But it doesn't matter, my rat software update it every time.

Please don't try to contact me or find me, it is impossible, since I sent you 
an email from your email account.

Through your e-mail, I uploaded malicious code to your Operation System.
I saved all of your contacts with friends, colleagues, relatives and a complete 
history of visits to the Internet resources.
Also I installed a rat software on your device and long tome spying for you.

You are not my only victim, I usually lock devices and ask for a ransom.
But I was struck by the sites of intimate content that you very often visit.

I am in shock of your reach fantasies! Wow! I've never seen anything like this!
I did not even know that SUCH content could be so exciting!

So, when you had fun on intime sites (you know what I mean!)
I made screenshot with using my program from your camera of yours device.
After that, I jointed them to the content of the currently viewed site.

Will be funny when I send these photos to your contacts! And if your relatives 
see it?
BUT I'm sure you don't want it. I definitely would not want to ...

I will not do this if you pay me a little amount.
I think $814 is a nice price for it!

I accept only Bitcoins.
My BTC wallet: 1HQ7wGdA5G9qUtM8jyDt5obDv1x3vEvjCy

If you have difficulty with this - Ask Google "how to make a payment on a 
bitcoin wallet". It's easy.
After receiving the above amount, all your data will be immediately removed 
automatically.
My virus will also will be destroy itself from your operating system.

My Trojan have auto alert, after this email is looked, I will be know it!

You have 2 days (48 hours) for make a payment.
If this does not happen - all your contacts will get crazy shots with your 
dirty life!
And so that you do not obstruct me, your device will be locked (also after 48 
hours)

Do not take this frivolously! This is the last warning!
Various security services or antiviruses won't help you for sure (I have 
already collected all your data).

Here are the recommendations of a professional:
Antiviruses do not help against modern malicious code. Just do not enter your 
passwords on unsafe sites!

I hope you will be prudent.
Bye.

Your Account Was Hacked!

[linux-kernel]

Hi, dear user of vger.kernel.org
We have installed one RAT software into you device.
For this moment your email account is hacked (see on "from address", I messaged 
you from your account).
Your password for linux-kernel@vger.kernel.org: qwerty

I have downloaded all confidential information from your system and I got some 
more evidence.
The most interesting moment that I have discovered are videos records where you 
masturbating.

I posted my virus on porn site, and then you installed it on your operation 
system.
When you clicked the button Play on porn video, at that moment my trojan was 
downloaded to your device.
After installation, your front camera shoots video every time you masturbate, 
in addition, the software is synchronized with the video you choose.

For the moment, the software has collected all your contact information from 
social networks and email addresses.
If you need to erase all of your collected data, send me $800 in BTC (crypto 
currency).
This is my Bitcoin wallet: 13cyEdT7kyH2f4j9xchvDGhv1o64MYNLUS
You have 48 hours after reading this letter.

After your transaction I will erase all your data.
Otherwise, I will send video with your pranks to all your colleagues and 
friends!!!

And henceforth be more careful!
Please visit only secure sites!
Bye!

[PATCH v4 0/4] rtc: add mxc driver for i.MX53 SRTC

[linux-kernel-dev]

From: Patrick Bruenn <p.bru...@beckhoff.com>

Neither rtc-imxdi, rtc-mxc nor rtc-snvs are compatible with i.MX53.

This is driver enables support for the low power domain SRTC features:
- 32-bit MSB of non-rollover time counter
- 32-bit alarm register

Select the new config option RTC_DRV_MXC_V2 to build this driver

Based on:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01

v4:
- rename "srtc" node into generic "rtc" keep the label as "srtc" to avoid
  duplication with imx53-m53.dtsi
- fix Signed-off-by: in bindings-patch

v3:
- introduce new config option with the same patch, which adds the driver
- call rtc_update_irq() only if necessary
- merge mxc_rtc_write_alarm_locked() with mxc_rtc_set_alarm()
- only use clk_enable/disable (without "prepare") during operation
- rebase on v4.15-rc3
- consistently use rtc_tm_to_time64() and time64_t
- refactor mxc_rtc_read_time(): don't lock for readl() only;
  don't rtc_valid_tm(); use time64_t
- check returncode of mxc_rtc_wait_for_flag()
- restructure mxc_rtc_sync_lp_locked() to replace pr_err() with
  dev_err_once(); remove explicit 'inline'
- don't touch imx_v4_v5_defconfig, instead add to imx_v6_v7_defconfig

v2:
- have seperate patches for dt-binding, CONFIG option, imx53.dtsi and driver
- add SPDX-License-Identifier and cleanup copyright notice
- replace __raw_readl/writel() with readl/writel()
- fix PM_SLEEP callbacks
- add CONFIG_RTC_DRV_MXC_V2 to build rtc-mxc_v2.c
- remove misleading or obvious comments and fix style of the remaining
- avoid endless loop while waiting for hw
- implement consistent locking; make spinlock a member of dev struct
- enable clk only for register accesses
- remove all udelay() calls since they are obsolete or redundant
  (we are already waiting for register flags to change)
- init platform_data before registering irq callback
- let set_time() fail, when 32 bit rtc counter exceeded
- make names more consistent
- cleanup and reorder includes
- cleanup and remove unused defines

[PATCH v3 3/4] rtc: add mxc driver for i.MX53 SRTC

[linux-kernel-dev]

From: Patrick Bruenn <p.bru...@beckhoff.com>

Neither rtc-imxdi, rtc-mxc nor rtc-snvs are compatible with i.MX53.

This is driver enables support for the low power domain SRTC features:
- 32-bit MSB of non-rollover time counter
- 32-bit alarm register

Select the new config option RTC_DRV_MXC_V2 to build this driver

Based on:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01

Signed-off-by: Patrick Bruenn <p.bru...@beckhoff.com>

Open issue:
- naming of the device tree node "rtc" vs. "srtc"

v3:
- introduce new config option with the same patch, which adds the driver
- call rtc_update_irq() only if necessary
- merge mxc_rtc_write_alarm_locked() with mxc_rtc_set_alarm()
- only use clk_enable/disable (without "prepare") during operation
- rebase on v4.15-rc3
- consistently use rtc_tm_to_time64() and time64_t
- refactor mxc_rtc_read_time(): don't lock for readl() only;
  don't rtc_valid_tm(); use time64_t
- check returncode of mxc_rtc_wait_for_flag()
- restructure mxc_rtc_sync_lp_locked() to replace pr_err() with
  dev_err_once(); remove explicit 'inline'
- don't touch imx_v4_v5_defconfig, instead add to imx_v6_v7_defconfig

v2:
- have seperate patches for dt-binding, CONFIG option, imx53.dtsi and driver
- add SPDX-License-Identifier and cleanup copyright notice
- replace __raw_readl/writel() with readl/writel()
- fix PM_SLEEP callbacks
- add CONFIG_RTC_DRV_MXC_V2 to build rtc-mxc_v2.c
- remove misleading or obvious comments and fix style of the remaining
- avoid endless loop while waiting for hw
- implement consistent locking; make spinlock a member of dev struct
- enable clk only for register accesses
- remove all udelay() calls since they are obsolete or redundant
  (we are already waiting for register flags to change)
- init platform_data before registering irq callback
- let set_time() fail, when 32 bit rtc counter exceeded
- make names more consistent
- cleanup and reorder includes
- cleanup and remove unused defines

[PATCH v3 0/4] rtc: add mxc driver for i.MX53 SRTC

[linux-kernel-dev]

From: Patrick Bruenn <p.bru...@beckhoff.com>

Neither rtc-imxdi, rtc-mxc nor rtc-snvs are compatible with i.MX53.

This is driver enables support for the low power domain SRTC features:
- 32-bit MSB of non-rollover time counter
- 32-bit alarm register

Select the new config option RTC_DRV_MXC_V2 to build this driver

Open issue:
- naming of the device tree node "rtc" vs. "srtc"

v3:
- introduce new config option with the same patch, which adds the driver
- call rtc_update_irq() only if necessary
- merge mxc_rtc_write_alarm_locked() with mxc_rtc_set_alarm()
- only use clk_enable/disable (without "prepare") during operation
- rebase on v4.15-rc3
- consistently use rtc_tm_to_time64() and time64_t
- refactor mxc_rtc_read_time(): don't lock for readl() only;
  don't rtc_valid_tm(); use time64_t
- check returncode of mxc_rtc_wait_for_flag()
- restructure mxc_rtc_sync_lp_locked() to replace pr_err() with
  dev_err_once(); remove explicit 'inline'
- don't touch imx_v4_v5_defconfig, instead add to imx_v6_v7_defconfig

v2:
- have seperate patches for dt-binding, CONFIG option, imx53.dtsi and driver
- add SPDX-License-Identifier and cleanup copyright notice
- replace __raw_readl/writel() with readl/writel()
- fix PM_SLEEP callbacks
- add CONFIG_RTC_DRV_MXC_V2 to build rtc-mxc_v2.c
- remove misleading or obvious comments and fix style of the remaining
- avoid endless loop while waiting for hw
- implement consistent locking; make spinlock a member of dev struct
- enable clk only for register accesses
- remove all udelay() calls since they are obsolete or redundant
  (we are already waiting for register flags to change)
- init platform_data before registering irq callback
- let set_time() fail, when 32 bit rtc counter exceeded
- make names more consistent
- cleanup and reorder includes
- cleanup and remove unused defines

[PATCH v3 0/4] rtc: add mxc driver for i.MX53 SRTC

[linux-kernel-dev]

From: Patrick Bruenn 

Neither rtc-imxdi, rtc-mxc nor rtc-snvs are compatible with i.MX53.

This is driver enables support for the low power domain SRTC features:
- 32-bit MSB of non-rollover time counter
- 32-bit alarm register

Select the new config option RTC_DRV_MXC_V2 to build this driver

[PATCH v2 0/5] add mxc driver for i.MX53 SRTC

[linux-kernel-dev]

From: Patrick Bruenn <p.bru...@beckhoff.com>

Neither rtc-imxdi, rtc-mxc nor rtc-snvs are compatible with i.MX53.

This is driver enables support for the low power domain SRTC features:
- 32-bit MSB of non-rollover time counter
- 32-bit alarm register

Based on:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01

v2:
- have seperate patches for dt-binding, CONFIG option, imx53.dtsi and driver
- add SPDX-License-Identifier and cleanup copyright notice
- replace __raw_readl/writel() with readl/writel()
- fix PM_SLEEP callbacks
- add CONFIG_RTC_DRV_MXC_V2 to build rtc-mxc_v2.c
- remove misleading or obvious comments and fix style of the remaining
- avoid endless loop while waiting for hw
- implement consistent locking; make spinlock a member of dev struct
- enable clk only for register accesses
- remove all udelay() calls since they are obsolete or redundant
  (we are already waiting for register flags to change)
- init platform_data before registering irq callback
- let set_time() fail, when 32 bit rtc counter exceeded
- make names more consistent
- cleanup and reorder includes
- cleanup and remove unused defines

[PATCH] rtc: add mxc driver for i.MX53

[linux-kernel-dev]

From: Patrick Bruenn <p.bru...@beckhoff.com>

Neither rtc-imxdi nor rtc-mxc are compatible with i.MX53.
Add a modernized version of mxc_v2 from here:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01

Changes to that version:
- updated to v4.15-rc1
- removed ioctl()
- removed proc()
- removed manual(redundant) enable_irq flag

Signed-off-by: Patrick Bruenn <p.bru...@beckhoff.com>

Open issues:
- driver naming, should it be merged with rtc-mxc.c ?
- document DT binding "fsl,imx53-rtc" accordingly
- Should unused defines be removed or kept for someone else to be
  useful?
- Is the use of __raw_readl/writel() correct? Should it be replaced with
  readl/writel()?
- suspend/resume() seems different to existing rtc-mxc.c, should I apply
  the pattern from rtc-mxc.c?
- On Shawns tree imx53.dtsi has been reverted already[1][2]. Should I split
  the imx53.dtsi change into a separate patch based on his tree? Or can
  we still stop the full revert and just remove the imx25-rtc compatible?
  I am not in a hurry, so we could just wait until the revert landed in
  Linus tree. Whatever you think is best.

[PATCH] rtc: add mxc driver for i.MX53

[linux-kernel-dev]

From: Patrick Bruenn 

Neither rtc-imxdi nor rtc-mxc are compatible with i.MX53.
Add a modernized version of mxc_v2 from here:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01

Changes to that version:
- updated to v4.15-rc1
- removed ioctl()
- removed proc()
- removed manual(redundant) enable_irq flag

Signed-off-by: Patrick Bruenn 

---

Open issues:
- driver naming, should it be merged with rtc-mxc.c ?
- document DT binding "fsl,imx53-rtc" accordingly
- Should unused defines be removed or kept for someone else to be
  useful?
- Is the use of __raw_readl/writel() correct? Should it be replaced with
  readl/writel()?
- suspend/resume() seems different to existing rtc-mxc.c, should I apply
  the pattern from rtc-mxc.c?
- On Shawns tree imx53.dtsi has been reverted already[1][2]. Should I split
  the imx53.dtsi change into a separate patch based on his tree? Or can
  we still stop the full revert and just remove the imx25-rtc compatible?
  I am not in a hurry, so we could just wait until the revert landed in
  Linus tree. Whatever you think is best.

[PATCH] Documentation: dt: rtc-imxdi: imx53-rtc is not compatible

[linux-kernel-dev]

From: Patrick Bruenn <p.bru...@beckhoff.com>

rtc-imxdi driver is not compatible with imx53-rtc like the example
suggested.
Only the raw timestamp register offsets match by accident, which has the
effect, that during startup/shutdown system clock syncronization with
rtc seems to work for imx53, too.
However hwclock and rtctest, will not work as expected on imx53.
To avoid future reverts like [1], we should adjust the documentation.

[PATCH v5 3/4] ARM: dts: imx53: add alternative UART2 configuration

[linux-kernel-dev]

From: Patrick Bruenn 

UART2 on EIM_D26 - EIM_D29 pins supports interchanging RXD/TXD pins
and RTS/CTS pins.
One board using these alternate settings is Beckhoff CX9020. Add the
alternative configuration here, to make it available to others, too.

[PATCH v5 4/4] ARM: dts: imx: add CX9020 Embedded PC device tree

[linux-kernel-dev]

From: Patrick Bruenn 

The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- no SATA connector
- CCAT FPGA connected to emi
- enable rtc
