| SYSCON reboot mode driver |
| |
| This driver gets reboot mode magic value form reboot-mode driver |
| and stores it in a SYSCON mapped register. Then the bootloader |
| can read it and take different action according to the magic |
| value stored. |
| |
| This DT node should be represented as a sub-node of a "syscon", "simple-mfd" |
| node. |
| |
| Required properties: |
| - compatible: should be "syscon-reboot-mode" |
| - offset: offset in the register map for the storage register (in bytes) |
| |
| Optional property: |
| - mask: bits mask of the bits in the register to store the reboot mode magic value, |
| default set to 0xffffffff if missing. |
| |
| The rest of the properties should follow the generic reboot-mode description |
| found in reboot-mode.txt |
| |
| Example: |
| pmu: pmu@20004000 { |
| compatible = "rockchip,rk3066-pmu", "syscon", "simple-mfd"; |
| reg = <0x20004000 0x100>; |
| |
| reboot-mode { |
| compatible = "syscon-reboot-mode"; |
| offset = <0x40>; |
| mode-normal = <BOOT_NORMAL>; |
| mode-recovery = <BOOT_RECOVERY>; |
| mode-bootloader = <BOOT_FASTBOOT>; |
| mode-loader = <BOOT_BL_DOWNLOAD>; |
| }; |
| }; |
