Subject: Re: [PATCH] arm64: dts: rockchip: Add Hugsun X99 IR receiver and
 power led

Hi Vivek,

The 'power-led' need some changes.

>From leds-gpio.yaml:

patternProperties:
  # The first form is preferred, but fall back to just 'led' anywhere in the
  # node name to at least catch some child nodes.
  "(^led-[0-9a-f]$|led)":
    type: object

Test with:
make -k ARCH=arm64 dtbs_check

arch/arm64/boot/dts/rockchip/rk3399-hugsun-x99.dt.yaml: leds:
power-led:linux,default-trigger:0: 'none' is not one of ['backlight',
'default-on', 'heartbeat', 'disk-activity', 'ide-disk', 'timer', 'pattern']

pwer => power

Test with linux-next.
