| Generic SYSCON mapped register poweroff driver |
| |
| This is a generic poweroff driver using syscon to map the poweroff register. |
| The poweroff is generally performed with a write to the poweroff register |
| defined by the register map pointed by syscon reference plus the offset |
| with the mask defined in the poweroff node. |
| |
| Required properties: |
| - compatible: should contain "syscon-poweroff" |
| - regmap: this is phandle to the register map node |
| - offset: offset in the register map for the poweroff register (in bytes) |
| - mask: the poweroff value written to the poweroff register (32 bit access) |
| |
| Default will be little endian mode, 32 bit access only. |
| |
| Examples: |
| |
| poweroff { |
| compatible = "syscon-poweroff"; |
| regmap = <®mapnode>; |
| offset = <0x0>; |
| mask = <0x7a>; |
| }; |
