+* Socionext Synquacer HS-SPI bindings
+
+Required Properties:
+- compatible: should be "socionext,synquacer-spi"
+- reg: physical base address of the controller and length of memory mapped
+       region.
+- clocks: Must contain an entry for rate source clock(s).
+- clock-names: Shall be "iHCLK" or "iPCLK". iHCLK is preferred over iPCLK
+
+Optional Properties:
+- num-cs: total number of chipselects
+- socionext,use-rtm: boolean, if required to use "retimed clock" for RX
+- socionext,set-aces: boolean, if same active clock edges field to be set.
+
+Example:
+
+	spi0: spi@ff110000 {
+		compatible = "socionext,synquacer-spi";
+		reg = <0xff110000 0x1000>;
+		clocks = <&clk_fip006_spi>;
+		clock-names = "iHCLK";
+		socionext,use-rtm;
+		socionext,set-aces;
