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

[Vivek Unune]

 - Add Hugsun X99 IR receiver and power led
 - Remove pwm0 node as it interferes with pwer LED gpio
   Also, it's not used in factory firmware
   
Tested with Libreelec kernel v5.6

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']

Test with linux-next.

Hi Johan,

I'll fix those in my next version. Here's what I intended to to:

1. Rename 'power-led' node to 'led-power'
2. Remove 'linux,default-trigger' entirely since this led is always on

Thanks,

Vivek

The first form is preferred.
Put 'led-power' in a regex tester with ^led-[0-9a-f]$
https://regex101.com/
Your regular expression does not match the subject string.

Test 'led-0'
Full match

Hi Johan,

Thanks for quick reply. 

Indeed led-power won't work. Although I'm trying to figure out the dtbs_check
Currently, make compains that it's missing.
I'll verify this properly without having you to verify it next time.

Thanks,

Vivek
