Subject: [PATCH v9 2/4] ARM: dts: berlin: Fix schema warnings for pwm-leds

The node names for devices using the pwm-leds driver follow a certain
naming scheme (now). Parent node name is not enforced, but recommended
by DT project.

DTC arch/arm/boot/dts/berlin2cd-google-chromecast.dt.yaml
CHECK arch/arm/boot/dts/berlin2cd-google-chromecast.dt.yaml
/home/alex/build/linux/arch/arm/boot/dts/berlin2cd-google-chromecast.dt.yaml: leds: 'red', 'white' do not match any of the regexes: '^led(-[0-9a-f]+)?$', 'pinctrl-[0-9]+'
From schema: /home/alex/src/linux/leds/Documentation/devicetree/bindings/leds/leds-pwm.yaml

Notes:
v8 -> v9:
* rebased on v5.11-rc1

v7 -> v8:
* rebased on recent pavel/for-next (post v5.10-rc1)

v6 -> v7:
* split up patch (one per sub arch)
* added actual warnings to commit message

Thanks for the patch.
I took this patch but sent out the PR late: https://www.spinics.net/lists/arm-kernel/msg862567.html
I will send out PR earlier for 5.12
