* Renesas R-Car SATA
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
- reg : address and length of the SATA registers;
- interrupts : must consist of one interrupt specifier.
Example:
sata: sata@fc600000 {
compatible = "renesas,sata-r8a7779";
reg = <0xfc600000 0x2000>;
interrupt-parent = <&gic>;
interrupts = <0 100 IRQ_TYPE_LEVEL_HIGH>;
};
