| Generic SYSCON mapped register reset driver |
| |
| This is a generic reset driver using syscon to map the reset register. |
| The reset is generally performed with a write to the reset register |
| defined by the register map pointed by syscon reference plus the offset |
| with the value and mask defined in the reboot node. |
| |
| Required properties: |
| - compatible: should contain "syscon-reboot" |
| - regmap: this is phandle to the register map node |
| - offset: offset in the register map for the reboot register (in bytes) |
| - value: the reset value written to the reboot register (32 bit access) |
| |
| Optional properties: |
| - mask: update only the register bits defined by the mask (32 bit) |
| |
| Legacy usage: |
| If a node doesn't contain a value property but contains a mask property, the |
| mask property is used as the value. |
| |
| Default will be little endian mode, 32 bit access only. |
| |
| Examples: |
| |
| reboot { |
| compatible = "syscon-reboot"; |
| regmap = <®mapnode>; |
| offset = <0x0>; |
| mask = <0x1>; |
| }; |
