+Renesas R-Car Gen3 RPC-IF MFD Device Tree Bindings
+--------------------------------------------------
+
+Required properties:
+- compatible: should be an SoC-specific compatible value, followed by
+ "renesas,rcar-gen3-rpc" as a fallback.
+ supported SoC-specific values are:
+ "renesas,r8a77995-rpc" (R-Car D3)
+- reg: should contain three register areas:
+ first for the base address of RPC-IF registers,
+ second for the direct mapping read mode and
+ third for the write buffer area.
+- reg-names: should contain "regs", "dirmap" and "wbuf"
+- clocks: should contain 1 entries for the module's clock
+- clock-names: should contain "rpc"
+- #address-cells: should be 1
+- #size-cells: should be 0
+
+Example:
+
+ rpc: rpc-if@ee200000 {
+ compatible = "renesas,r8a77995-rpc", "renesas,rcar-gen3-rpc";
+ reg = <0 0xee200000 0 0x200>, <0 0x08000000 0 0x4000000>,
+ <0 0xee208000 0 0x100>;
+ reg-names = "regs", "dirmap", "wbuf";
+ clocks = <&cpg CPG_MOD 917>;
+ clock-names = "rpc";
+ power-domains = <&sysc R8A77995_PD_ALWAYS_ON>;
+ resets = <&cpg 917>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ flash@0 {
+ compatible = "jedec,spi-nor";
+ reg = <0>;
+ spi-max-frequency = <40000000>;
+ spi-tx-bus-width = <1>;
+ spi-rx-bus-width = <1>;
+ };
+ };
