I wouldn't mind, but I'm not sure how to do so in a meaningful way that wouldn't result in, for instance, a file name renesas,du-r8a7791.yaml that would contain bindings for all of - renesas,du-r8a7743 - renesas,du-r8a7744 - renesas,du-r8a7791 - renesas,du-r8a7793 which I think would be quite confusing, or one file per SoC with lots of duplications, which doesn't sound great either :-S If there's a better split, I'd be happy to implement it. > > Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> > > --- > > Changes since v1: > > > > - Use pattern instead of enum for dclkin > > - Update MAINTAINERS > > --- > > .../bindings/display/renesas,du.txt | 145 --- > > .../bindings/display/renesas,du.yaml | 854 ++++++++++++++++++ > > MAINTAINERS | 2 +- > > 3 files changed, 855 insertions(+), 146 deletions(-) > > delete mode 100644 Documentation/devicetree/bindings/display/renesas,du.txt > > create mode 100644 Documentation/devicetree/bindings/display/renesas,du.yaml > > > > diff --git a/Documentation/devicetree/bindings/display/renesas,du.yaml b/Documentation/devicetree/bindings/display/renesas,du.yaml > > new file mode 100644 > > index 000000000000..f56ef3eed742 > > --- /dev/null > > +++ b/Documentation/devicetree/bindings/display/renesas,du.yaml > > @@ -0,0 +1,854 @@ > > +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) > > +%YAML 1.2 > > +--- > > +$id: http://devicetree.org/schemas/display/renesas,du.yaml# > > +$schema: http://devicetree.org/meta-schemas/core.yaml# > > + > > +title: Renesas R-Car Display Unit (DU) > > + > > +maintainers: > > + - Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> > > + > > +description: | > > + These DT bindings describe the Display Unit embedded in the Renesas R-Car > > + Gen1, R-Car Gen2, R-Car Gen3, RZ/G1 and RZ/G2 SoCs. > > + > > +properties: > > + compatible: > > + enum: > > + - renesas,du-r8a7742 # for RZ/G1H compatible DU > > + - renesas,du-r8a7743 # for RZ/G1M compatible DU > > + - renesas,du-r8a7744 # for RZ/G1N compatible DU > > + - renesas,du-r8a7745 # for RZ/G1E compatible DU > > + - renesas,du-r8a77470 # for RZ/G1C compatible DU > > + - renesas,du-r8a774a1 # for RZ/G2M compatible DU > > + - renesas,du-r8a774b1 # for RZ/G2N compatible DU > > + - renesas,du-r8a774c0 # for RZ/G2E compatible DU > > + - renesas,du-r8a774e1 # for RZ/G2H compatible DU > > + - renesas,du-r8a7779 # for R-Car H1 compatible DU > > + - renesas,du-r8a7790 # for R-Car H2 compatible DU > > + - renesas,du-r8a7791 # for R-Car M2-W compatible DU > > + - renesas,du-r8a7792 # for R-Car V2H compatible DU > > + - renesas,du-r8a7793 # for R-Car M2-N compatible DU > > + - renesas,du-r8a7794 # for R-Car E2 compatible DU > > + - renesas,du-r8a7795 # for R-Car H3 compatible DU > > + - renesas,du-r8a7796 # for R-Car M3-W compatible DU > > + - renesas,du-r8a77961 # for R-Car M3-W+ compatible DU > > + - renesas,du-r8a77965 # for R-Car M3-N compatible DU > > + - renesas,du-r8a77970 # for R-Car V3M compatible DU > > + - renesas,du-r8a77980 # for R-Car V3H compatible DU > > + - renesas,du-r8a77990 # for R-Car E3 compatible DU > > + - renesas,du-r8a77995 # for R-Car D3 compatible DU > > + > > + reg: > > + maxItems: 1 > > + > > + # See compatible-specific constraints below. > > + clocks: true > > + clock-names: true > > + interrupts: true > > + resets: true > > + reset-names: true > > + > > + ports: > > + type: object > > + description: | > > + The connections to the DU output video ports are modeled using the OF > > + graph bindings specified in Documentation/devicetree/bindings/graph.txt. > > + The number of ports and their assignment are model-dependent.
