[PATCH] arch: arm64: dts: add big-endian property back into watchdog node

[PATCH] arch: arm64: dts: add big-endian property back into watchdog node

[Meng Li]

When verifying watchdog feature on NXP ls1046ardb board,
it doesn't work. Because the big-endian is deleted by accident,
add it back.

It is not removed by accident. It was removed intentionally. Bring
arguments (bindings, hardware, drivers) why this is correct choice.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: failed to guess base

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

fix tags should be wrong.

I remember I tested without big-endian. If it is wrong, please revert original
patch and provide enough reason.

Sorry, forget previous comments. You are right. It is accident remove big-endian
at watchdog@2ad0000.

7c8ffc5555cb should only remove big-endina for mmc nodes.

The fixed patch author has reviewed this patch.  big-endian property is removed by accident.
I have verified this patch on big-endian property with driver ./drivers/watchdog/imx2_wdt.c.

Although you said you understand my patch in your next email, do you think I still need to improve my commit log more clearly, and send a v2 patch?
For example, describe that only the big-endian of watchdog node is remove by accident, and the mmc works fine. Only add the big-endian for watchdog feature.

Yes, you'd better descript why it is accident remove.

I have a question.
I checked the code of ./drivers/watchdog/imx2_wdt.c, there is below item imx2_wdt_dt_ids[]
{ .compatible = "fsl,ls1043a-wdt", .data = &imx_wdt_legacy },
Do you think we also need to add another below item for ls1046?
{ .compatible = "fsl,ls1046a-wdt", .data = &imx_wdt_legacy },

Another question
I also checked the code ./arch/arm64/boot/dts/freescale/fsl-ls1043a.dtsi, and I found out below item in watchdog@2ad0000 node
compatible = "fsl,ls1043a-wdt", "fsl,imx21-wdt";
but in imx2_wdt_dt_ids[], there is also the below item, it also can support the ls1043a and ls1046a platforms
{ .compatible = "fsl,imx21-wdt", .data = &imx_wdt_legacy },
So, I think maybe we can remove the { .compatible = "fsl,ls1043a-wdt", .data = &imx_wdt_legacy }.

Based on above description, there are 2 solutions, add { .compatible = "fsl,ls1046a-wdt", .data = &imx_wdt_legacy }, or remove { .compatible = "fsl,ls1043a-wdt", .data = &imx_wdt_legacy }.
What is your suggestion？

Thanks,
LImeng

{ .compatible = "fsl,imx21-wdt", .data = &imx_wdt_legacy }, it is enough
by use fallback fsl,imx21-wdt.

Yes, but not nessesary to do that. leave it as it.

leave driver code unchange. the current driver can work.
