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)":
