    ARM: dts: rockchip: rename and label gpio-led subnodes · f0344b33
    Johan Jonker authored
    Current dts files with 'gpio-led' nodes were manually verified.
    In order to automate this process leds-gpio.txt
    has been converted to yaml. With this conversion a check
    for pattern properties was added. A test with the command
    below gives a screen full of warnings like:
    
    arch/arm/boot/dts/rk3188-radxarock.dt.yaml: gpio-leds:
    'blue', 'green', 'sleep'
    do not match any of the regexes:
    '(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'
    
    Fix these errors with help of the following rules:
    
    1: Add nodename in the preferred form.
    
    2: Always add a label that ends with '_led' to prevent conflicts
       with other labels such as 'power' and 'mmc'
    
    3: If leds need pinctrl add a label that ends with '_led_pin'
       also to prevent conflicts with other labels.
    
    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)":
    
    make ARCH=arm dtbs_check

    leds-gpio.yaml
