Subject: [PATCH 1/1] dt-bindings: leds: Convert leds-tlc591xx.txt to yaml format
Convert binding doc leds-tlc591xx.txt to yaml format to fix below DTB_CHECK
warning.
arch/arm64/boot/dts/freescale/imx8mp-aristainetos3-proton2s.dtb:
/soc@...us@...00000/i2c@...30000/tlc59108@40: failed to match any schema with compatible: ['ti,tlc59108']
Additional change:
- ref to common.yaml for child nodes.
- limit child's reg to 0 - 7 for ti,tlc59108.
- fix typo 'linux,default_trigger' in example.
- change child node name's prefix to led-.
- change nodename to led-controller.
- fix properties order in example.
