This series adds support for some peripherals installed on
Samsung Galaxy S5 (SM-G900H). This includes the WiFi card,
GPIO keys, fuel gauge, touchkeys, notification LED and display.
Also documents the peripherals for which we currently lack drivers.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check` (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).

This is a requirement since few months (half a year?).

Best regards,
Krzysztof

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation

Most likely this is led-controller
