[PATCH] arm64: dts: qcom: sdm630-nile: add pinctrl for camera key
Posted by Sebastian Raase 1 year, 10 months ago 
Add pinctrl configuration for gpio-keys. Without this,
camera button half-presses are not detected.

Tested on discovery and pioneer.

Looks missing suffix (state) and test, so:

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

Best regards,

All existing pinctrl definitions use pinctrl-names first, so I followed the existing file. Is this still okay?

I did add the suffix and ran the test, and the warning is gone now. Sent an updated patch.

No, not all. If you are sending v2, why you cannot fix this in new code?

It's fine to keep the "non-preferred" order, I'll probably send some
changes to nile and fix up the style while at it in the near future.

Sebastian,
Although it is also preferred to implement feedback the reviewer is
asking. I don't understand why you insisted to keep the other order.

I simply followed the existing style and did not know any better.
Since you called it a "nit", I wrongly assumed that was acceptable.

Fixed in v3.
