-DT bindings for the Renesas Advanced Power Management Unit
-
-Renesas R-Car and RZ/G1 SoCs utilize one or more APMU hardware units
-for CPU core power domain control including SMP boot and CPU Hotplug.
-
-Required properties:
-
-- compatible: Should be "renesas,<soctype>-apmu", "renesas,apmu" as fallback.
- Examples with soctypes are:
- - "renesas,r8a7743-apmu" (RZ/G1M)
- - "renesas,r8a7744-apmu" (RZ/G1N)
- - "renesas,r8a7745-apmu" (RZ/G1E)
- - "renesas,r8a77470-apmu" (RZ/G1C)
- - "renesas,r8a7790-apmu" (R-Car H2)
- - "renesas,r8a7791-apmu" (R-Car M2-W)
- - "renesas,r8a7792-apmu" (R-Car V2H)
- - "renesas,r8a7793-apmu" (R-Car M2-N)
- - "renesas,r8a7794-apmu" (R-Car E2)
-
-- reg: Base address and length of the I/O registers used by the APMU.
-
-- cpus: This node contains a list of CPU cores, which should match the order
- of CPU cores used by the WUPCR and PSTR registers in the Advanced Power
- Management Unit section of the device's datasheet.
-
-
-Example:
-
-This shows the r8a7791 APMU that can control CPU0 and CPU1.
-
- apmu@e6152000 {
- compatible = "renesas,r8a7791-apmu", "renesas,apmu";
- reg = <0 0xe6152000 0 0x188>;
- cpus = <&cpu0 &cpu1>;
- };
