Generic MTK RGU mapped register reset driver
|
|
|
|
This is a reset driver using toprgu to map its non-volatile register.
|
|
The reset is generally performed with a write to the non-volatile register
|
|
defined by the register map pointed by toprgu reference plus the offset
|
|
with the mask defined in the reboot-mode node.
|
|
|
|
Required properties:
|
|
- compatible: should contain "toprgu-reboot-mode"
|
|
- regmap: this is phandle to the register map node
|
|
- offset: offset in the register map for the reboot-mode register (in bytes)
|
|
- mask: the reset value written to the reboot register (32 bit access)
|
|
|
|
Examples:
|
|
reboot-mode {
|
|
compatible = "toprgu-reboot-mode";
|
|
regmap = <&toprgu>;
|
|
offset = <0x24>;
|
|
mask = <0xF>;
|
|
};
|
|
|
|
Optional properties - reboot mode value that will keep in toprgu nonrst RG:
|
|
- mode-charger = <BOOT_CHARGER>;
|
|
- mode-recovery = <BOOT_RECOVERY>;
|
|
- mode-bootloader = <BOOT_BOOTLOADER>;
|
|
- mode-dm-verity-dev-corrupt = <BOOT_DM_VERITY>;
|
|
- mode-kpoc = <BOOT_KPOC>;
|
|
- mode-ddr-reserve = <BOOT_DDR_RSVD>;
|
|
- mode-meta = <BOOT_META>;
|
|
- mode-rpmbpk = <BOOT_RPMBPK>; |
