[v2] MAINTAINERS: add myself as maintainer for QorIQ PTP clock driver

[Yangbo Lu]

Added myself as maintainer for QorIQ PTP clock driver.
Since gianfar_ptp.c was renamed to ptp_qoriq.c, let's
maintain it under QorIQ PTP clock driver.

[PATCH 3/5] net: ethernet: gianfar_ethtool: get phc index through drvdata

[Yangbo Lu]

Global variable gfar_phc_index was used to get and store
phc index through gianfar_ptp driver. However gianfar_ptp
had been renamed as ptp_qoriq for QorIQ common PTP driver.
This gfar_phc_index doesn't work any more, and the phc index
is stored in drvdata now. This patch is to support getting
phc index through ptp_qoriq drvdata.

[PATCH 1/5] ptp: rework gianfar_ptp as QorIQ common PTP driver

[Yangbo Lu]

gianfar_ptp was the PTP clock driver for 1588 timer
module of Freescale QorIQ eTSEC (Enhanced Three-Speed
Ethernet Controllers) platforms. Actually QorIQ DPAA
(Data Path Acceleration Architecture) platforms is
also using the same 1588 timer module in hardware.

This patch is to rework gianfar_ptp as QorIQ common
PTP driver to support both DPAA and eTSEC. Moved
gianfar_ptp.c to drivers/ptp/, renamed it as
ptp_qoriq.c, and renamed many variables. There were
not any function changes.

 * Gianfar PTP clock nodes
 
-General Properties:
-
-  - compatible   Should be "fsl,etsec-ptp"
-  - reg  Offset and length of the register set for the device
-  - interrupts   There should be at least two interrupts. Some devices
- have as many as four PTP related interrupts.
-
-Clock Properties:
-
-  - fsl,ckselTimer reference clock source.
-  - fsl,tclk-period  Timer reference clock period in nanoseconds.
-  - fsl,tmr-prsc Prescaler, divides the output clock.
-  - fsl,tmr-add  Frequency compensation value.
-  - fsl,tmr-fiper1   Fixed interval period pulse generator.
-  - fsl,tmr-fiper2   Fixed interval period pulse generator.
-  - fsl,max-adj  Maximum frequency adjustment in parts per billion.
-
-  These properties set the operational parameters for the PTP
-  clock. You must choose these carefully for the clock to work right.
-  Here is how to figure good values:
-
-  TimerOsc = selected reference clock   MHz
-  tclk_period  = desired clock period   nanoseconds
-  NominalFreq  = 1000 / tclk_period MHz
-  FreqDivRatio = TimerOsc / NominalFreq (must be greater that 1.0)
-  tmr_add  = ceil(2^32 / FreqDivRatio)
-  OutputClock  = NominalFreq / tmr_prsc MHz
-  PulseWidth   = 1 / OutputClockmicroseconds
-  FiperFreq1   = desired frequency in Hz
-  FiperDiv1= 100 * OutputClock / FiperFreq1
-  tmr_fiper1   = tmr_prsc * tclk_period * FiperDiv1 - tclk_period
-  max_adj  = 10 * (FreqDivRatio - 1.0) - 1
-
-  The calculation for tmr_fiper2 is the same as for tmr_fiper1. The
-  driver expects that tmr_fiper1 will be correctly set to produce a 1
-  Pulse Per Second (PPS) signal, since this will be offered to the PPS
-  subsystem to synchronize the Linux clock.
-
-  Reference clock source is determined by the value, which is holded
-  in CKSEL bits in TMR_CTRL register. "fsl,cksel" property keeps the
-  value, which will be directly written in those bits, that is why,
-  according to reference manual, the next clock sources can be used:
-
-  <0> - external high precision timer reference clock (TSEC_TMR_CLK
-input is used for this purpose);
-  <1> - eTSEC system clock;
-  <2> - eTSEC1 transmit clock;
-  <3> - RTC clock input.
-
-  When this attribute is not used, eTSEC system clock will serve as
-  IEEE 1588 timer reference clock.
-
-Example:
-
-   ptp_clock@24e00 {
-   compatible = "fsl,etsec-ptp";
-   reg = <0x24E00 0xB0>;
-   interrupts = <12 0x8 13 0x8>;
-   interrupt-parent = <  >;
-   fsl,cksel   = <1>;
-   fsl,tclk-period = <10>;
-   fsl,tmr-prsc= <100>;
-   fsl,tmr-add = <0x99A4>;
-   fsl,tmr-fiper1  = <0x3B9AC9F6>;
-   fsl,tmr-fiper2  = <0x00018696>;

[v2] net: gianfar_ptp: move set_fipers() to spinlock protecting area

[Yangbo Lu]

set_fipers() calling should be protected by spinlock in
case that any interrupt breaks related registers setting
and the function we expect. This patch is to move set_fipers()
to spinlock protecting area in ptp_gianfar_adjtime().

[PATCH] net: gianfar: add ethtool eee support

[Yangbo Lu]

From: Shaohui Xie <shaohui@nxp.com>

Gianfar does not support EEE, but it can connect to a PHY which supports
EEE and the PHY advertises EEE by default, and its link partner also
advertises EEE, so the PHY enters low power mode when traffic rate is low,
which causes packet loss if an application's traffic rate is low. This
patch provides .get_eee and .set_eee so that to disable the EEE
advertisement via ethtool if needed, other EEE features are not supported.

The eSDHC of T4240-R1.0-R2.0 has incorrect vender version and spec version.
Acturally the right version numbers should be VVN=0x13 and SVN = 0x1.
This patch adds the GUTS driver support for eSDHC driver to match SoC.
And fix host version to avoid that incorrect version numbers break down

[v16, 6/7] base: soc: Check for NULL SoC device attributes

[Yangbo Lu]

From: Geert Uytterhoeven 

If soc_device_match() is used to check the value of a specific
attribute that is not present for the current SoC, the kernel crashes
with a NULL pointer dereference.

Fix this by explicitly checking for the absence of a needed property,
and considering this a non-match.

[v16, 5/7] base: soc: introduce soc_device_match() interface

[Yangbo Lu]

From: Arnd Bergmann <a...@arndb.de>

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.

Common reasons for doing this include:

- A machine is not using devicetree or similar for passing data about
  on-chip devices, but just announces their presence using boot-time
  platform devices, and the machine code itself does not care about the
  revision.

- There is existing firmware or boot loaders with existing DT binaries
  with generic compatible strings that do not identify the particular
  revision of each device, but the driver knows which SoC revisions
  include which part.

- A prerelease version of a chip has some quirks and we are using the same
  version of the bootloader and the DT blob on both the prerelease and the
  final version. An update of the DT binding seems inappropriate because
  that would involve maintaining multiple copies of the dts and/or
  bootloader.

This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.

Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

[Yangbo Lu]

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate

This patch adds a driver to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.

[v16, 0/7] Fix eSDHC host version register bug

[Yangbo Lu]

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 15 previous version
patchsets had tried many methods but all of them were rejected by reviewers.
Such as
- dts compatible method
- syscon method
- ifdef PPC method
- GUTS driver getting SVR method
Anrd suggested a soc_device_match method in v10, and this is the only available
method left now. This v11 patchset introduces the soc_device_match interface in
soc driver.

The first four patches of Yangbo are to add the GUTS driver. This is used to
register a soc device which contain soc version and revision information.
The other three patches introduce the soc_device_match method in soc driver
and apply it on esdhc driver to fix this bug.

[v15, 4/7] soc: fsl: add GUTS driver for QorIQ platforms

[Yangbo Lu]

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.

This patch adds a driver to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.

[v15, 6/7] base: soc: introduce soc_device_match() interface

[Yangbo Lu]

From: Arnd Bergmann <a...@arndb.de>

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.

Common reasons for doing this include:

- A machine is not using devicetree or similar for passing data about
  on-chip devices, but just announces their presence using boot-time
  platform devices, and the machine code itself does not care about the
  revision.

- There is existing firmware or boot loaders with existing DT binaries
  with generic compatible strings that do not identify the particular
  revision of each device, but the driver knows which SoC revisions
  include which part.

- A prerelease version of a chip has some quirks and we are using the same
  version of the bootloader and the DT blob on both the prerelease and the
  final version. An update of the DT binding seems inappropriate because
  that would involve maintaining multiple copies of the dts and/or
  bootloader.

This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.

Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

[v15, 7/7] mmc: sdhci-of-esdhc: fix host version for T4240-R1.0-R2.0

[Yangbo Lu]

The eSDHC of T4240-R1.0-R2.0 has incorrect vender version and spec version.
Acturally the right version numbers should be VVN=0x13 and SVN = 0x1.
This patch adds the GUTS driver support for eSDHC driver to match SoC.
And fix host version to avoid that incorrect version numbers break down
the ADMA data transfer.

Anrd suggested a soc_device_match method in v10, and this is the only available
method left now. This v11 patchset introduces the soc_device_match interface in
soc driver.

The first five patches of Yangbo are to add the GUTS driver. This is used to
register a soc device which contain soc version and revision information.
The other two patches introduce the soc_device_match method in soc driver
and apply it on esdhc driver to fix this bug.

Changes for v15:
- Dropped patch 'dt: bindings: update Freescale DCFG compatible'
  since the work had been done by below patch on ShawnGuo's linux tree.
  'dt-bindings: fsl: add LS1043A/LS1046A/LS2080A compatible for SCFG
   and DCFG'
- Fixed error code issue in guts driver

[v14, 7/8] base: soc: introduce soc_device_match() interface

[Yangbo Lu]

From: Arnd Bergmann <a...@arndb.de>

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.

Common reasons for doing this include:

- A machine is not using devicetree or similar for passing data about
  on-chip devices, but just announces their presence using boot-time
  platform devices, and the machine code itself does not care about the
  revision.

- There is existing firmware or boot loaders with existing DT binaries
  with generic compatible strings that do not identify the particular
  revision of each device, but the driver knows which SoC revisions
  include which part.

- A prerelease version of a chip has some quirks and we are using the same
  version of the bootloader and the DT blob on both the prerelease and the
  final version. An update of the DT binding seems inappropriate because
  that would involve maintaining multiple copies of the dts and/or
  bootloader.

This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.

Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

[v14, 5/8] soc: fsl: add GUTS driver for QorIQ platforms

[Yangbo Lu]

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.

This patch adds a driver to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.

[v14, 4/8] powerpc/fsl: move mpc85xx.h to include/linux/fsl

[Yangbo Lu]

Move mpc85xx.h to include/linux/fsl and rename it to svr.h as a common
header file.  This SVR numberspace is used on some ARM chips as well as
PPC, and even to check for a PPC SVR multi-arch drivers would otherwise
need to ifdef the header inclusion and all references to the SVR symbols.

[v14, 0/8] Fix eSDHC host version register bug

[Yangbo Lu]

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 10 previous version
patchsets had tried many methods but all of them were rejected by reviewers.
Such as
- dts compatible method
- syscon method
- ifdef PPC method
- GUTS driver getting SVR method
Anrd suggested a soc_device_match method in v10, and this is the only available
method left now. This v11 patchset introduces the soc_device_match interface in
soc driver.

The first six patches of Yangbo are to add the GUTS driver. This is used to
register a soc device which contain soc version and revision information.
The other two patches introduce the soc_device_match method in soc driver
and apply it on esdhc driver to fix this bug.

[v13, 4/8] powerpc/fsl: move mpc85xx.h to include/linux/fsl

[Yangbo Lu]

Move mpc85xx.h to include/linux/fsl and rename it to svr.h as a common
header file.  This SVR numberspace is used on some ARM chips as well as
PPC, and even to check for a PPC SVR multi-arch drivers would otherwise
need to ifdef the header inclusion and all references to the SVR symbols.

[v13, 7/8] base: soc: introduce soc_device_match() interface

[Yangbo Lu]

From: Arnd Bergmann <a...@arndb.de>

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.

Common reasons for doing this include:

- A machine is not using devicetree or similar for passing data about
  on-chip devices, but just announces their presence using boot-time
  platform devices, and the machine code itself does not care about the
  revision.

- There is existing firmware or boot loaders with existing DT binaries
  with generic compatible strings that do not identify the particular
  revision of each device, but the driver knows which SoC revisions
  include which part.

- A prerelease version of a chip has some quirks and we are using the same
  version of the bootloader and the DT blob on both the prerelease and the
  final version. An update of the DT binding seems inappropriate because
  that would involve maintaining multiple copies of the dts and/or
  bootloader.

This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.

Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

[v13, 5/8] soc: fsl: add GUTS driver for QorIQ platforms

[Yangbo Lu]

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.

This patch adds a driver to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.

[v13, 0/8] Fix eSDHC host version register bug

[Yangbo Lu]

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 10 previous version
patchsets had tried many methods but all of them were rejected by reviewers.
Such as
- dts compatible method
- syscon method
- ifdef PPC method
- GUTS driver getting SVR method
Anrd suggested a soc_device_match method in v10, and this is the only available
method left now. This v11 patchset introduces the soc_device_match interface in
soc driver.

The first six patches of Yangbo are to add the GUTS driver. This is used to
register a soc device which contain soc version and revision information.
The other two patches introduce the soc_device_match method in soc driver
and apply it on esdhc driver to fix this bug.

[v12, 5/8] soc: fsl: add GUTS driver for QorIQ platforms

[Yangbo Lu]

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.

This patch adds a driver to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.

[v12, 8/8] mmc: sdhci-of-esdhc: fix host version for T4240-R1.0-R2.0

[Yangbo Lu]

The eSDHC of T4240-R1.0-R2.0 has incorrect vender version and spec version.
Acturally the right version numbers should be VVN=0x13 and SVN = 0x1.
This patch adds the GUTS driver support for eSDHC driver to match SoC.
And fix host version to avoid that incorrect version numbers break down
the ADMA data transfer.

Move mpc85xx.h to include/linux/fsl and rename it to svr.h as a common
header file.  This SVR numberspace is used on some ARM chips as well as
PPC, and even to check for a PPC SVR multi-arch drivers would otherwise
need to ifdef the header inclusion and all references to the SVR symbols.

[v12, 7/8] base: soc: introduce soc_device_match() interface

[Yangbo Lu]

From: Arnd Bergmann <a...@arndb.de>

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.

Common reasons for doing this include:

- A machine is not using devicetree or similar for passing data about
  on-chip devices, but just announces their presence using boot-time
  platform devices, and the machine code itself does not care about the
  revision.

- There is existing firmware or boot loaders with existing DT binaries
  with generic compatible strings that do not identify the particular
  revision of each device, but the driver knows which SoC revisions
  include which part.

- A prerelease version of a chip has some quirks and we are using the same
  version of the bootloader and the DT blob on both the prerelease and the
  final version. An update of the DT binding seems inappropriate because
  that would involve maintaining multiple copies of the dts and/or
  bootloader.

This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.

Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

[v12, 0/8] Fix eSDHC host version register bug

[Yangbo Lu]

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 10 previous version
patchsets had tried many methods but all of them were rejected by reviewers.
Such as
- dts compatible method
- syscon method
- ifdef PPC method
- GUTS driver getting SVR method
Anrd suggested a soc_device_match method in v10, and this is the only available
method left now. This v11 patchset introduces the soc_device_match interface in
soc driver.

The first six patches of Yangbo are to add the GUTS driver. This is used to
register a soc device which contain soc version and revision information.
The other two patches introduce the soc_device_match method in soc driver
and apply it on esdhc driver to fix this bug.

[v11, 7/8] base: soc: introduce soc_device_match() interface

[Yangbo Lu]

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.

Common reasons for doing this include:

- A machine is not using devicetree or similar for passing data about
  on-chip devices, but just announces their presence using boot-time
  platform devices, and the machine code itself does not care about the
  revision.

- There is existing firmware or boot loaders with existing DT binaries
  with generic compatible strings that do not identify the particular
  revision of each device, but the driver knows which SoC revisions
  include which part.

- A prerelease version of a chip has some quirks and we are using the same
  version of the bootloader and the DT blob on both the prerelease and the
  final version. An update of the DT binding seems inappropriate because
  that would involve maintaining multiple copies of the dts and/or
  bootloader.

This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.

Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

[v11, 5/8] soc: fsl: add GUTS driver for QorIQ platforms

[Yangbo Lu]

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.

This patch adds a driver to manage and access global utilities block.
Initially only reading SVR and registering soc device are supported.
Other guts accesses, such as reading RCW, should eventually be moved
into this driver as well.

I think your proof-of-concept patch is still in discussion. Some answers are 
needed from you to
address Scott's comments on your patchset. Have you reached an agreement?

[Yangbo Lu]

Hi Arnd,

Could you reply when you see the email?
If your method doesn’t resolve the problem, we still want to use our old 
patchset.

This guts driver had been discussed about one year and blocked many workaround 
upstream.
So please help to review and comment soon.

Thanks a lot.

[PATCH] gianfar: fix the last transmit buffer descriptor

[Yangbo Lu]

When the transmit hardware timestamping is enabled, an additional
TxBD would be added and would be set as the last TxBD with TXBD_LAST
and TXBD_INTERRUPT. However this has been broken by a patch recently.
This made the software couldn't get transmit hardware timestamps and
resulted in call trace. So, this patch is to fix this issue.

Fixes: 48963b4492e9 ("gianfar: Remove redundant ops for do_tstamp
   from xmit()")

Hi Arnd,

Any comments? 
Please reply when you see the email since we want this eSDHC issue to be fixed 
soon.

All the patches are Freescale-specific and is to fix the eSDHC driver.
Could we let them merged first if you were talking about a new way of 
abstracting getting SoC version.


Thanks :)

[v10, 0/7] Fix eSDHC host version register bug

[Yangbo Lu]

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To get the SoC version and revision, it's needed to add the
GUTS driver to access the global utilities registers.

So, the first four patches are to add the GUTS driver.
The following patches except the updating MAINTAINERS patch are to enable
GUTS driver support to get SVR in eSDHC driver and fix host version for T4240.

[v9, 0/7] Fix eSDHC host version register bug

[Yangbo Lu]

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To get the SoC version and revision, it's needed to add the
GUTS driver to access the global utilities registers.

So, the first four patches are to add the GUTS driver.
The following patches except the updating MAINTAINERS patch are to enable
GUTS driver support to get SVR in eSDHC driver and fix host version for T4240.

[v8, 0/7] Fix eSDHC host version register bug

[Yangbo Lu]

This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To get the SoC version and revision, it's needed to add the
GUTS driver to access the global utilities registers.

So, the first four patches are to add the GUTS driver.
The following patches except the updating MAINTAINERS patch are to enable
GUTS driver support to get SVR in eSDHC driver and fix host version for T4240.

[v8, 7/7] mmc: sdhci-of-esdhc: fix host version for T4240-R1.0-R2.0

[Yangbo Lu]

The eSDHC of T4240-R1.0-R2.0 has incorrect vender version and spec version.
Acturally the right version numbers should be VVN=0x13 and SVN = 0x1.
This patch adds the GUTS driver support for eSDHC driver to get SVR(System
version register). And fix host version to avoid that incorrect version
numbers break down the ADMA data transfer.

[Lu Yangbo-B47093] Could give some advice on the MAINTAINERS for these 'fsl'

since I really don’t know who should be the right person?
I will appreciate that!

[v7, 2/5] soc: fsl: add GUTS driver for QorIQ platforms

[Yangbo Lu]

The global utilities block controls power management, I/O device
enabling, power-onreset(POR) configuration monitoring, alternate
function selection for multiplexed signals,and clock control.

This patch adds GUTS driver to manage and access global utilities
block.
