[PATCH v6 08/12] pinctrl: Ingenic: Add pinctrl driver for JZ4730.
Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.
This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

[PATCH v6 04/12] pinctrl: Ingenic: Improve LCD pins related code.
1.In the JZ4740 part, remove pointless "lcd-no-pins", use "lcd-special"
and "lcd-generic" instead "lcd-18bit-tft". Currently, in the mainline,
no other devicetree out there is using the "lcd-18bit-tft" ABI, so we
should be able to replace it safely.
2.In the JZ4725B part, adjust the location of the LCD pins related code
to keep them consistent with the style of other parts.
3.In the JZ4760 part, add the missing comma and adjust element order in
"jz4760_lcd_special_pins[]", keep them in the order of CLS/SPL/PS/REV
like other "lcd_special_pins" arrays. And adjust the location of the
"jz4760_lcd_generic" related code to keep them consistent with the
style of other parts.
4.In the JZ4770 part, remove pointless "lcd-no-pins", add the missing
"lcd-16bit", "lcd-18bit", "lcd-special", "lcd-generic".
5.In the X1000 part and the X1500 part, remove pointless "lcd-no-pins".
6.In the X1830 part, replace "lcd-rgb-18bit" with "lcd-tft-8bit" and
"lcd-tft-24bit", because of the description of the TRANS_CONFIG.MODE
register bits in the PM manual of the X1830, shows that the X1830 only
supppots 24bit mode and 8bit mode for tft interface, only 18 pins in
the GPIO table are because of the data[17:16], the data[9:8], and the
data[1:0] has not been connected. And according to the description,
the two interfaces supported by X1830 are respectively referred to as
"TFT interface" and "SLCD interface", so the "lcd-rgb-xxx" is replaced
with "lcd-tft-xxx" to avoid confusion.

[PATCH v5 07/11] pinctrl: Ingenic: Add pinctrl driver for JZ4730.
Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.
This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

[PATCH v5 04/11] pinctrl: Ingenic: Improve LCD pins related code.
1.In the JZ4740 part, remove pointless "lcd-no-pins", use "lcd-special"
and "lcd-generic" instead "lcd-18bit-tft". Currently, in the mainline,
no other devicetree out there is using the "lcd-18bit-tft" ABI, so we
should be able to replace it safely.
2.In the JZ4725B part, adjust the location of the LCD pins related code
to keep them consistent with the style of other parts.
3.In the JZ4760 part, add the missing comma and adjust element order in
"jz4760_lcd_special_pins[]", keep them in the order of CLS/SPL/PS/REV
like other "lcd_special_pins" arrays. And adjust the location of the
"jz4760_lcd_generic" related code to keep them consistent with the
style of other parts.
4.In the JZ4770 part, remove pointless "lcd-no-pins", add the missing
"lcd-16bit", "lcd-18bit", "lcd-special", "lcd-generic".
5.In the X1000 part and the X1500 part, remove pointless "lcd-no-pins".
6.In the X1830 part, replace "lcd-rgb-18bit" with "lcd-tft-8bit" and
"lcd-tft-24bit", because of the description of the TRANS_CONFIG.MODE
register bits in the PM manual of the X1830, shows that the X1830 only
supppots 24bit mode and 8bit mode for tft interface, only 18 pins in
the GPIO table are because of the data[17:16], the data[9:8], and the
data[1:0] has not been connected. And according to the description,
the two interfaces supported by X1830 are respectively referred to as
"TFT interface" and "SLCD interface", so the "lcd-rgb-xxx" is replaced
with "lcd-tft-xxx" to avoid confusion.

[PATCH v4 07/11] pinctrl: Ingenic: Add pinctrl driver for JZ4730.
Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.
This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

Notes:
v3:
New patch.
v3->v4:
1.Use "lcd-special" and "lcd-generic" instead "lcd-16bit-tft".
2.Adjust function names to avoid confusion.
3.Improve the structure of some functions.
4.Modify the format of comment.
5.Simplify code using GENMASK.
6.Drop unnecessary mask.

[PATCH v4 04/11] pinctrl: Ingenic: Improve LCD pins related code.
1.In the JZ4740 part, remove pointless "lcd-no-pins", use "lcd-special"
and "lcd-generic" instead "lcd-18bit-tft". Currently, in the mainline,
no other devicetree out there is using the "lcd-18bit-tft" ABI, so we
should be able to replace it safely.
2.In the JZ4725B part, adjust the location of the LCD pins related code
to keep them consistent with the style of other parts.
3.In the JZ4760 part, add the missing comma and adjust element order in
"jz4760_lcd_special_pins[]", keep them in the order of CLS/SPL/PS/REV
like other "lcd_special_pins" arrays. And adjust the location of the
"jz4760_lcd_generic" related code to keep them consistent with the
style of other parts.
4.In the JZ4770 part, remove pointless "lcd-no-pins", add the missing
"lcd-16bit", "lcd-18bit", "lcd-special", "lcd-generic".
5.In the X1000 part and the X1500 part, remove pointless "lcd-no-pins".
6.In the X1830 part, replace "lcd-rgb-18bit" with "lcd-tft-8bit" and
"lcd-tft-24bit", because of the description of the TRANS_CONFIG.MODE
register bits in the PM manual of the X1830, shows that the X1830 only
supppots 24bit mode and 8bit mode for tft interface, only 18 pins in
the GPIO table are because of the data[17:16], the data[9:8], and the
data[1:0] has not been connected. And according to the description,
the two interfaces supported by X1830 are respectively referred to as
"TFT interface" and "SLCD interface", so the "lcd-rgb-xxx" is replaced
with "lcd-tft-xxx" to avoid confusion.

Re: [PATCH v3] mm: fix race by making init_zero_pfn() early_initcall
Hi Ilya,
On 2021/3/30 下午12:42, Ilya Lipnitskiy wrote:
There are code paths that rely on zero_pfn to be fully initialized
before core_initcall. For example, wq_sysfs_init() is a core_initcall
function that eventually results in a call to kernel_execve, which
causes a page fault with a subsequent mmput. If zero_pfn is not
initialized by then it may not get cleaned up properly and result in an
error:
BUG: Bad rss-counter state mm:(ptrval) type:MM_ANONPAGES val:1
Here is an analysis of the race as seen on a MIPS device. On this
particular MT7621 device (Ubiquiti ER-X), zero_pfn is PFN 0 until
initialized, at which point it becomes PFN 5120:
1. wq_sysfs_init calls into kobject_uevent_env at core_initcall:

[<8033f8b8>] kset_register+0x68/0x88

[<8066bca0>] kernel_init+0x10/0x100
[<80003038>] ret_from_kernel_thread+0x14/0x1c
2. kobject_uevent_env() calls call_usermodehelper_exec() which executes
kernel_execve asynchronously.
3. Memory allocations in kernel_execve cause a page fault, bumping the
MM reference counter:
[<8015adb4>] add_mm_counter_fast+0xb4/0xc0
[<80160d58>] handle_mm_fault+0x6e4/0xea0
[<80158aa4>] __get_user_pages.part.78+0x190/0x37c

[<801a880c>] kernel_execve+0x11c/0x298
[<800420f4>] call_usermodehelper_exec_async+0x114/0x194
4. In case zero_pfn has not been initialized yet, zap_pte_range does
not decrement the MM_ANONPAGES RSS counter and the BUG message is
triggered shortly afterwards when __mmdrop checks the ref counters:
[<800285e8>] __mmdrop+0x98/0x1d0
[<801a6de8>] free_bprm+0x44/0x118
[<801a86a8>] kernel_execve+0x160/0x1d8
[<800420f4>] call_usermodehelper_exec_async+0x114/0x194
[<80003198>] ret_from_kernel_thread+0x14/0x1c
To avoid races such as described above, initialize init_zero_pfn at
early_initcall level. Depending on the architecture, ZERO_PAGE is either
constant or gets initialized even earlier, at paging_init, so there is
no issue with initializing zero_pfn earlier.

The following error appears when running Linux 5.10.18 on an embedded
MIPS mt7621 target:
[0.301219] BUG: Bad rss-counter state mm:(ptrval) type:MM_ANONPAGES val:1
Being a very generic error, I started digging and added a stack dump
before the BUG:
Call Trace:

[<80003198>] ret_from_kernel_thread+0x14/0x1c
So that's how I got to looking at fs/exec.c and noticed quite a few
changes last year. Turns out this message only occurs once very early
at boot during the very first call to kernel_execve. current->mm is
NULL at this stage, so acct_arg_size() is effectively a no-op.
If you believe this is a new error you could bisect the kernel
to see which change introduced the behavior you are seeing.
More digging, and I traced the RSS counter increment to:
[<8015adb4>] add_mm_counter_fast+0xb4/0xc0
[<80160d58>] handle_mm_fault+0x6e4/0xea0
[<80158aa4>] __get_user_pages.part.78+0x190/0x37c

[<80003198>] ret_from_kernel_thread+0x14/0x1c
In fact, I also checked vma_pages(bprm->vma) and lo and behold it is set to 1.
How is fs/exec.c supposed to handle implied RSS increments that happen
due to page faults when discarding the bprm structure? In this case,
the bug-generating kernel_execve call never succeeded, it returned -2,
but I didn't trace exactly what failed.
Unless I am mistaken any left over pages should be purged by exit_mmap
which is called by mmput before mmput calls mmdrop.
Good to know. Some more digging and I can say that we hit this error
when trying to unmap PFN 0 (is_zero_pfn(pfn) returns TRUE,
vm_normal_page returns NULL, zap_pte_range does not decrement
MM_ANONPAGES RSS counter). Is my understanding correct that PFN 0 is
usable, but special? Or am I totally off the mark here?
It would be good to know if that is the page that get_user_pages_remote
returned to copy_string_kernel. The zero page that is always zero,
should never be returned when a writable mapping is desired.
Indeed, pfn 0 is returned from get_arg_page: (page is 0x809cf000,
page_to_pfn(page) is 0) and it is the same page that is being freed and not
refcounted in mmput/zap_pte_range. Confirmed with good old printk. Also,
ZERO_PAGE(0)==0x809fc000 -> PFN 5120.
I think I have found the problem though, after much digging and thanks to all
the information provided. init_zero_pfn() gets called too late (after
the call to
is_zero_pfn(0) from mmput returns true), until then zero_pfn == 0, and after,
zero_pfn == 5120. Boom.
So PFN 0 is special, but only for a little bit, enough for something
on my system
to call kernel_execve :)
Question: is my system not supposed to be calling kernel_execve this
early or does
init_zero_pfn() need to happen earlier? init_zero_pfn is currently a
core_initcall.
Looking quickly it seems that init_zero_pfn() is in mm/memory.c and is
common for both mips and x86. Further it appears init_zero_pfn() has
been that was since 2009 a13ea5b75964 ("mm: reinstate ZERO_PAGE").
Given the testing that x86 gets and that nothing like this has been
reported it looks like whatever driver is triggering the kernel_execve
is doing something wrong.
Because honestly. If the zero page isn't working there is not a chance
that anything in userspace is working so it is clearly much too early.
I suspect there is some driver that is initialized very early that is
doing something that looks innocuous (like triggering a hotplug event)
and that happens to cause a call_usermode_helper which then calls
kernel_execve.
I will investigate the offenders more closely. However, I do not
notice this behavior on the same system based on the 5.4 kernel. Is it
I also encountered this problem on Ingenic X1000 and X1830. This is the
printed information:
[0.120715] BUG: Bad rss-counter state mm:(ptrval)
type:MM_ANONPAGES val:1
I tested kernel 5.9, kernel 5.10, kernel 5.11, and kernel 5.12, only
kernel 5.9 did not have this problem, so we can know that this problem
was introduced in kernel 5.10, have you found any effective solution?

Coud you either split this into several groups (lcd-8bit, lcd-16bit,
lcd-18bit, lcd-24bit, lcd-special, lcd-generic) like it is done for
the JZ4725B? Same for the other SoCs.
Sure, and do we need to change the JZ4740 (and the previous JZ4750)
to the lcd-special + lcd-generic model? It looks more reasonable than
the original lcd-tft and makes the style more uniform.
Yes, please change it for the JZ4750 too.
For the JZ4740, in theory it is too late - these are ABI and we
shouldn't change them.
With that said - the only board that has a JZ4740 and is still
supported (although untested, so it's not even sure it still boots) is
the Ben Nanonote, which only uses the "lcd-8bit" group. So it's
probably fine.
Sure, I will do it.
Cheers,
-Paul
Alternatively just remove the "lcd" function for now.
+ { "lcd-no-pins", },
And remove this.
Cheers,

Coud you either split this into several groups (lcd-8bit, lcd-16bit,
lcd-18bit, lcd-24bit, lcd-special, lcd-generic) like it is done for
the JZ4725B? Same for the other SoCs.
Sure, and do we need to change the JZ4740 (and the previous JZ4750) to
the lcd-special + lcd-generic model? It looks more reasonable than the
original lcd-tft and makes the style more uniform.
Alternatively just remove the "lcd" function for now.
+ { "lcd-no-pins", },
And remove this.
Cheers,

I had to look up operator precedence in C, '*' and '%' have the same

I'd suggest adding parentheses around the '%' to make it more obvious.

This fixes a commit that was introduced in an older kernel (than the

Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.
This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

Please correct me if I am wrong, according to the PM, when the
register value of OD is 0, 1, 2, 3, the value corresponding
participating PL frequency calculation is 1, 2, 4, 8. Therefore, change
m = (rate / MHZ) * ++od * n / (parent_rate / MHZ); to m = (rate /
MHZ) * (2 ^ od++) * n / (parent_rate / MHZ); seems to be more
appropriate, it can avoid 3, 5, 6, and 7 that should not exist.
I found a mistake. My brain must have been broken at that time. The 2 ^
od here I intended to express the meaning of od power of 2, but it
should be written as 1 << od, otherwise it becomes a XOR operation.
You are totally correct. I will send a revised version.
Thanks!

[PATCH] USB: DWC2: Add VBUS overcurrent detection control.
Introduce configurable option for enabling GOTGCTL register
bits VbvalidOvEn and VbvalidOvVal. Once selected it disables
VBUS overcurrent detection.
This patch is derived from Dragan Čečavac (in the kernel 3.18
tree of CI20). It is very useful for the MIPS Creator CI20(r1).
Without this patch, CI20's OTG port has a great probability to
face overcurrent warning, which breaks the OTG functionality.

The following error appears when running Linux 5.10.18 on an embedded
MIPS mt7621 target:
[0.301219] BUG: Bad rss-counter state mm:(ptrval) type:MM_ANONPAGES val:1
Being a very generic error, I started digging and added a stack dump
before the BUG:
Call Trace:

[<80003198>] ret_from_kernel_thread+0x14/0x1c
So that's how I got to looking at fs/exec.c and noticed quite a few
changes last year. Turns out this message only occurs once very early
at boot during the very first call to kernel_execve. current->mm is
NULL at this stage, so acct_arg_size() is effectively a no-op.
If you believe this is a new error you could bisect the kernel
to see which change introduced the behavior you are seeing.
More digging, and I traced the RSS counter increment to:

[<80160d58>] handle_mm_fault+0x6e4/0xea0

[<80003198>] ret_from_kernel_thread+0x14/0x1c
In fact, I also checked vma_pages(bprm->vma) and lo and behold it is set to 1.
How is fs/exec.c supposed to handle implied RSS increments that happen
due to page faults when discarding the bprm structure? In this case,
the bug-generating kernel_execve call never succeeded, it returned -2,
but I didn't trace exactly what failed.
Unless I am mistaken any left over pages should be purged by exit_mmap
which is called by mmput before mmput calls mmdrop.
Good to know. Some more digging and I can say that we hit this error
when trying to unmap PFN 0 (is_zero_pfn(pfn) returns TRUE,
vm_normal_page returns NULL, zap_pte_range does not decrement
MM_ANONPAGES RSS counter). Is my understanding correct that PFN 0 is
usable, but special? Or am I totally off the mark here?
It would be good to know if that is the page that get_user_pages_remote
returned to copy_string_kernel. The zero page that is always zero,
should never be returned when a writable mapping is desired.
Indeed, pfn 0 is returned from get_arg_page: (page is 0x809cf000,
page_to_pfn(page) is 0) and it is the same page that is being freed and not
refcounted in mmput/zap_pte_range. Confirmed with good old printk. Also,
ZERO_PAGE(0)==0x809fc000 -> PFN 5120.
I think I have found the problem though, after much digging and thanks to all
the information provided. init_zero_pfn() gets called too late (after
the call to
is_zero_pfn(0) from mmput returns true), until then zero_pfn == 0, and after,
zero_pfn == 5120. Boom.
So PFN 0 is special, but only for a little bit, enough for something
on my system
to call kernel_execve :)
Question: is my system not supposed to be calling kernel_execve this
early or does
init_zero_pfn() need to happen earlier? init_zero_pfn is currently a
core_initcall.
Looking quickly it seems that init_zero_pfn() is in mm/memory.c and is
common for both mips and x86. Further it appears init_zero_pfn() has
been that was since 2009 a13ea5b75964 ("mm: reinstate ZERO_PAGE").
Given the testing that x86 gets and that nothing like this has been
reported it looks like whatever driver is triggering the kernel_execve
is doing something wrong.
Because honestly. If the zero page isn't working there is not a chance
that anything in userspace is working so it is clearly much too early.
I suspect there is some driver that is initialized very early that is
doing something that looks innocuous (like triggering a hotplug event)
and that happens to cause a call_usermode_helper which then calls
kernel_execve.
I will investigate the offenders more closely. However, I do not
notice this behavior on the same system based on the 5.4 kernel. Is it
I also encountered this problem on Ingenic X1000 and X1830. This is the
printed information:
[ 0.120715] BUG: Bad rss-counter state mm:(ptrval)
type:MM_ANONPAGES val:1
I tested kernel 5.9, kernel 5.10, kernel 5.11, and kernel 5.12, only
kernel 5.9 did not have this problem, so we can know that this problem
was introduced in kernel 5.10, have you found any effective solution?
Thanks and best regards!
possible that last year's exec changes have exposed this issue? Not
blaming exec at all, just making sure I understand the problem better.

Re: [PATCH] I2C: JZ4780: Fix bug for Ingenic X1000.
Hi Wolfram,
Sorry, please forgive my carefulness, I wrongly sent the version that
did not clean up, resulting in missing the reporter's information and
some errors in formats.

Any write operation? I wonder then why nobody noticed before?
The standard I2C communication should look like this:
Read:
device_addr + w, reg_addr, device_addr + r, data;
Write:
device_addr + w, reg_addr, data;
But without this patch, it looks like this:
Read:
device_addr + w, reg_addr, device_addr + r, data;
Write:
device_addr + w, reg_addr, device_addr + w, data;
This is clearly not correct.
When I added support for X1000 to this driver, the hardware used was
CU1000-Neo. On this hardware, there was an ADS7830 that communicated
through I2C, but the operation of ADS7830 only involved read operations,
so I was at that time failed to realize the problem with the write
operation.
In addition, because X1000 did not implement relatively complete support
in the mainline until the second half of 2020, there are still a large
number of users who are still using the old SDK (kernel 3.10 and
kernel4.4) provided by Ingenics, which may also be indirectly delayed
exposure of this problem.
- while ((i2c_sta & JZ4780_I2C_STA_TFNF) &&
- (i2c->wt_len > 0)) {
+ while ((i2c_sta & JZ4780_I2C_STA_TFNF) && (i2c->wt_len
> 0)) {
This is a cosmetic change only IIUC. Shouldn't be in a bugfix.
My fault, I will remove it in the next version.
Thanks and best regards!

[PATCH v3 06/10] pinctrl: Ingenic: Add pinctrl driver for JZ4730.
Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.
This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

the JZ4750 SoC, the JZ4755 SoC, the JZ4775 SoC and the X2000 SoC from
Ingenic.
The driver of JZ4730 is derived from Paul Boddie. It is worth noting
that the JZ4730 is special in having two control registers
(upper/lower),
so add code to handle the jz4730 specific register offsets and some
register pairs have 2 bits for each GPIO pin.
Can you split this patch again, one commit per SoC?
Sure, I will split it.
Cheers,
-Paul

"bias" is a 2-bit value (because of the & 3 mask), and

OK, I will fix it in the next version.

I think you can keep the switch outside the if/else block, if you use
pullup/pulldown variables.
These can be initialized (in the non-X1830 case) to:
pullup = pull && (jzpc->info->pull_ups[offt] & BIT(idx));
pulldown = pull && (jzpc->info->pull_downs[offt] & BIT(idx));
In the X1830 case you'd initialize these variables from 'bias'.
Sure, I will do this in the next version.

Here would change to if (pullup || pulldown)

Maybe list them in order?
I ordered them in the order of rxd3, rxd2, txd3, txd2, rxclk, crs, col.
And are you sure that's the whole list? The PM (section 12.2 in
jz4770_pm_part3.pdf) lists more pins.
Here is the way to imitate the MMC. Use only RMII group when using RMII
function, use both RMII and MII groups when using MII function. If you
think it is necessary, I can redefine the MII group.
Thanks and best regards!

[PATCH v2 6/6] pinctrl: Ingenic: Add support for new Ingenic SoCs.
Add support for probing the pinctrl-ingenic driver on the JZ4730 SoC,
the JZ4750 SoC, the JZ4755 SoC, the JZ4775 SoC and the X2000 SoC from
Ingenic.
The driver of JZ4730 is derived from Paul Boddie. It is worth noting
that the JZ4730 is special in having two control registers (upper/lower),
so add code to handle the jz4730 specific register offsets and some
register pairs have 2 bits for each GPIO pin.

Hi,
Here are a set of patches to add support for the Ingenic JZ4760(B) SoCs.
One thing to note is that the ingenic,jz4760-tcu is undocumented for now,
as I will update the TCU documentation in a different patchset.
Zhou: the CGU code now supports overriding the PLL M/N/OD calc
algorithm, please tell me if it works for you.
The previously mentioned problems have all been solved, this proves that
your patch is available for I2S PLL.
I will improve and clean up the relevant code, then send it immediately
after your patches is merged.
Thanks and best regards!

[PATCH 3/3] pinctrl: Ingenic: Add support for new Ingenic SoCs.
Add support for probing the pinctrl-ingenic driver on the JZ4730 SoC,
the JZ4750 SoC, the JZ4755 SoC, the JZ4775 SoC and the X2000 SoC from
Ingenic.
The driver of JZ4730 is derived from Paul Boddie. It is worth noting
that the JZ4730 is special in having two control registers (upper/lower),
so add code to handle the jz4730 specific register offsets and some
register pairs have 2 bits for each GPIO pin.

Hi,
Here are a set of patches to add support for the Ingenic JZ4760(B) SoCs.
One thing to note is that the ingenic,jz4760-tcu is undocumented for now,
as I will update the TCU documentation in a different patchset.
Zhou: the CGU code now supports overriding the PLL M/N/OD calc
algorithm, please tell me if it works for you.
Newly found two problems, the first problem is because I2S PLL does not
have a stable bit, so we need to follow the bypass bit, which is only do
corresponding processing when "stable_bit > = 0".
The second problem is that the I2S PLL cannot switch the parent clock
after using the PLL framework, so it cannot use SCLKA and MPLL as the
parent clock (when trying to switch the parent clock, it will stuck and
accompany "clk: failed to reparent i2s to mpll: -22").
Cheers,
-Paul

Zhou: the CGU code now supports overriding the PLL M/N/OD calc
algorithm, please tell me if it works for you.
After set "od = 1;", the overriding works, but I think we still need
some further improvements related to OD,
because there is no OD bits in the I2S PLL, this will cause error in
"ingenic_pll_recalc_rate()", and may cause
"ingenic_pll_calc()" to also have error(if we will introduce support for
non 1 od values).
I think maybe we can add codes to detect if there is an
"pll_od_encoding". If it is NULL, it means no OD bits, then
do some corresponding processing( for example, setting corresponding
variable to 1) to ensure proper calculation.
Thanks and best regards!

No change.
v3->v4:
1.The -1 used for placeholders on the unused bits of the

2.Move "JZ4780_CLK_CORE1" from the "Gate-only clocks"
class to the "Custom (SoC-specific)" class, because
it belongs to the custom clock.

Notes:
v1->v2:
Add I2S clock for X1000.
v2->v3:
Correct the comment in x1000-cgu.c, change it from
"Custom (SoC-specific) OTG PHY" to "Custom (SoC-specific)",
since there is more than just the "OTG PHY" clock.
v3->v4:
No change.
