| DT bindings for the Renesas Advanced Power Management Unit |
| |
| Renesas R-Car line of 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,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>; |
| }; |
