Subject: [PATCH v5 03/20] dt-bindings: power: mediatek: Refine multiple level power domain nodes
Extract duplicated properties and support more levels of power
domain nodes.
This change fix following error when do dtbs_check,
arch/arm64/boot/dts/mediatek/mt8195-evb.dtb: power-controller:
power-domain@15:power-domain@16:power-domain@18: 'power-domain@19',
'power-domain@20', 'power-domain@21' do not match any of the regexes:
'pinctrl-[0-9]+'
