We will use the "power-domains" property in new DTs, and we will get a "make dtbs_check" warning if we don't add the "power-domains" in yaml, so we add it, but should not be a "required property", we will send a new version for it. And another series patch will fix the "dtbs_check"(mediatek,larb) you mentioned before: https://patchwork.kernel.org/project/linux-mediatek/list/?series=633993 Thanks Best Regards > > > > > Signed-off-by: Irui Wang <irui.wang@xxxxxxxxxxxx> > > --- > > .../devicetree/bindings/media/mediatek,vcodec-encoder.yaml | 7 > > +++++++ > > 1 file changed, 7 insertions(+) > > > > diff --git > > a/Documentation/devicetree/bindings/media/mediatek,vcodec- > > encoder.yaml > > b/Documentation/devicetree/bindings/media/mediatek,vcodec- > > encoder.yaml > > index deb5b657a2d5..3c069c965992 100644 > > --- a/Documentation/devicetree/bindings/media/mediatek,vcodec- > > encoder.yaml > > +++ b/Documentation/devicetree/bindings/media/mediatek,vcodec- > > encoder.yaml > > @@ -41,6 +41,9 @@ properties: > > > > assigned-clock-parents: true > > > > + power-domains: > > + maxItems: 1 > > + > > iommus: > > minItems: 1 > > maxItems: 32 > > @@ -72,6 +75,7 @@ required: > > - iommus > > - assigned-clocks > > - assigned-clock-parents > > + - power-domains > > > > allOf: > > - if: > > @@ -132,6 +136,7 @@ examples: > > #include <dt-bindings/clock/mt8173-clk.h> > > #include <dt-bindings/memory/mt8173-larb-port.h> > > #include <dt-bindings/interrupt-controller/irq.h> > > + #include <dt-bindings/power/mt8173-power.h> > > > > vcodec_enc_avc: vcodec@18002000 { > > compatible = "mediatek,mt8173-vcodec-enc"; > > @@ -153,6 +158,7 @@ examples: > > clock-names = "venc_sel"; > > assigned-clocks = <&topckgen CLK_TOP_VENC_SEL>; > > assigned-clock-parents = <&topckgen CLK_TOP_VCODECPLL>; > > + power-domains = <&scpsys MT8173_POWER_DOMAIN_VENC>; > > }; > > > > vcodec_enc_vp8: vcodec@19002000 { > > @@ -173,4 +179,5 @@ examples: > > clock-names = "venc_lt_sel"; > > assigned-clocks = <&topckgen CLK_TOP_VENC_LT_SEL>; > > assigned-clock-parents = <&topckgen > > CLK_TOP_VCODECPLL_370P5>; > > + power-domains = <&scpsys MT8173_POWER_DOMAIN_VENC_LT>; > > }; > > -- > > 2.18.0 > > > >
