Subject: Applied "dt-bindings: spi: Document Renesas R-Car Gen3 RPC-IF controller bindings" to the spi tree

The patch

   dt-bindings: spi: Document Renesas R-Car Gen3 RPC-IF controller bindings

has been applied to the spi tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

+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,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@...00000 {
+		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>;
+		};
+	};
