+* Renesas R-Car SATA
+
+Required properties:
+- compatible : should contain one or more of the following:
+ - "renesas,sata-r8a7779" for R-Car H1
+ - "renesas,sata-r8a7790-es1" for R-Car H2 ES1
+ - "renesas,sata-r8a7790" for R-Car H2 other than ES1
+ - "renesas,sata-r8a7791" for R-Car M2-W
+ - "renesas,sata-r8a7793" for R-Car M2-N
+ - "renesas,sata-r8a7795" for R-Car H3
+ - "renesas,sata-r8a77965" for R-Car M3-N
+ - "renesas,rcar-gen2-sata" for a generic R-Car Gen2 compatible device
+ - "renesas,rcar-gen3-sata" for a generic R-Car Gen3 compatible device
+ - "renesas,rcar-sata" is deprecated
+
+ When compatible with the generic version nodes
+ must list the SoC-specific version corresponding
+ to the platform first followed by the generic
+ version.
+
+- reg : address and length of the SATA registers;
+- interrupts : must consist of one interrupt specifier.
+- clocks : must contain a reference to the functional clock.
+
+Example:
+
+sata0: sata@ee300000 {
+ compatible = "renesas,sata-r8a7791", "renesas,rcar-gen2-sata";
+ reg = <0 0xee300000 0 0x2000>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 105 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp8_clks R8A7791_CLK_SATA0>;
+};
