Thanks Andrew for your prompt response!
Sure I will use the proper options in git format-patch at the next time, thanks for the tips :-)
Our team will review your comments and submit updated version soon.
Best Regards,

Hello Hongwei,
Thanks for the patch!
I think this is the second or third iteration? If you send an updated patch in the future please make sure to use the `-v` option as well as`--subject-prefix` to `git format-patch` - this changes the subject to e.g. `[PATCH linux dev-5.0 v2]` and allows us to identify why you've sent the patch from reading the subject.

Can you please add the pinmux properties for the ADC lines that you're using?
The iio-hwmon node suggests you're using lines 0-7.

This is missing the pinctrl-0 property.
I think in the last version of the patch you had this set to:
pinctrl-0 = <&pinctrl_spi1debug_default>;
and I queried how the board was strapped - you still need the pinctrl-0 node, but what I should have been clearer about was that you should probably be using the following instead:
pinctrl-0 = <&pinctrl_spi1_default>;
unless your board is strapped for SPI debug mode. This is something you'll need to check on the schematics, as pinctrl won't modify the strapping value to accommodate the devicetree in this case.
Otherwise, the patch looks okay to me!
Cheers,
Andrew
