Required properties:
- compatible : should contain one of the following:
- "renesas,sata-r8a7779" for R-Car H1
- - "renesas,sata-r8a7790" for R-Car H2
- - "renesas,sata-r8a7791" for R-Car M2
+ ("renesas,rcar-sata" is deprecated)
+ - "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
- 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:
-sata: sata@fc600000 {
- compatible = "renesas,sata-r8a7779";
- reg = <0xfc600000 0x2000>;
+sata0: sata@ee300000 {
+ compatible = "renesas,sata-r8a7791";
+ reg = <0 0xee300000 0 0x2000>;
interrupt-parent = <&gic>;
- interrupts = <0 100 IRQ_TYPE_LEVEL_HIGH>;
+ interrupts = <0 105 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp8_clks R8A7791_CLK_SATA0>;
