Hi Geert, 
 
Thanks for your review!

Will fix it as 

+Renesas R-Car Gen3 RPC-IF controller 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,r8a77980-rpc"          (R-Car 
V3H)
+                                "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 the clock phandle/specifier pair for the module 
clock.
+- clock-names: should contain "rpc"
+- power-domains: should contain the power domain phandle/secifier pair.
+- resets: should contain the reset controller phandle/specifier pair.
+- #address-cells: should be 1
+- #size-cells: should be 0
+
+  flash: should be represented by a subnode of the RPC-IF node, 
+  which "compatible" property contains "jedec,spi-nor", it presents SPI 
is used.
+
+Example:
+
+                rpc: spi@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>;
+                                };
+                };

Is it OK ?

thanks & best regards,
Mason
