Does the DRIF IP block present on the M3-N (r8a77965) function without support for this register in the driver? If not then I think that: 1) This patch should be updated to note that renesas,rcar-gen3-drif can only be used with H3 (r8a7795) and M3-W (r8a77995). 2) A driver patch is required 3) The DT patch, 2/2 of this series, should be updated to i) Not use renesas,rcar-gen3-drif ii) Extend the register aperture from 0x64 to 0x84. > --- > Documentation/devicetree/bindings/media/renesas,drif.txt | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/Documentation/devicetree/bindings/media/renesas,drif.txt b/Documentation/devicetree/bindings/media/renesas,drif.txt > index 0d8974a..16cdee3 100644 > --- a/Documentation/devicetree/bindings/media/renesas,drif.txt > +++ b/Documentation/devicetree/bindings/media/renesas,drif.txt > @@ -41,6 +41,7 @@ Required properties of an internal channel: > ------------------------------------------- > - compatible: "renesas,r8a7795-drif" if DRIF controller is a part of R8A7795 SoC. > "renesas,r8a7796-drif" if DRIF controller is a part of R8A7796 SoC. > + "renesas,r8a77965-drif" if DRIF controller is a part of R8A77965 SoC. > "renesas,rcar-gen3-drif" for a generic R-Car Gen3 compatible device. > > When compatible with the generic version, nodes must list the > -- > 2.7.4 >
