This is a patch series for cpuidle driver for Sunplus SP7021 SoC.

Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates
many peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and 
etc.) into a single chip. It is designed for industrial control.

Refer to:
https://sunplus-tibbo.atlassian.net/wiki/spaces/doc/overview
https://tibbo.com/store/plus1.html

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

Hi Rob:

Look into the full log, it show you check 3 programs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Context	Check	Description
robh/checkpatch	warning	total: 0 errors, 1 warnings, 67 lines checked
robh/dt-meta-schema	success	
robh/dtbs-check	fail	build log
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1) The checkpatch warning is WARNING: From:/Signed-off-by: email address mismatch: 'From: Edwin chiu <edwinchiu0505tw@gmail.com>' != 'Signed-off-by: Edwin chiu <edwin.chiu@sunplus.com>'
==> I want explain to you that <edwin.chiu@sunplus.com> is my email in the company, but it disagree operate by "git send-email".
    So I used <edwinchiu0505tw@gmail.com> in my linux system to operate with "git send-email".
   Actually I checkpatch in my side was 0 error 0 warning.

2) Regarding to dtbs-check issue, your list warnings related to others company's yaml file, it not my yaml file case. 
   What is the purpose you want? Or what should I do?

3) Execute=>make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/arm/sunplus/sunplus,idle-state.yaml
There are many config select items…..I don't know how to select them.
(I execute "make config " and "make all" were pass)
Can you teach me how to do "make dtbs_check"?

The email used to send and the author emails are independent in git. 
There should be a 'From:' line in the resulting patch when the sender 
and author don't match.

Maybe you need to set sendemail.from config option to your corp email.

You aren't adding anything custom, so why are you even adding the 
schema? arm/idle-states.yaml should be enough.

Did you read Documentation/devicetree/bindings/writing-schema.rst?

To check all dts files (for an arch) and run the validation, do:

make allmodconfig
make dtbs_check

    It disagree operate by "git send-email".
   But I am pretty sure I can receive email on both edwin.chiu@sunplus.com and edwinchiu0505tw@gmail.com .

===> Yes, I want to apply arm/idle-state structure to my idle function.
    I thought every function submit, all need edit yaml file together.
    Do you mean I can submit cpuidle-sunplus.c without my sunplus,idle-state.yaml ?

On the other hand, I confirm my yaml file can pass dt_binding_check and dtbs_check as below:
