This driver parse the reboot commands like "reboot loader" and "reboot recovery" to get a boot mode described in the device tree , then call the corresponding write interfae to store the boot mode in some place like special register or ram , which can be read by the bootloader after system reboot. This is commonly done on Android based devices, in order to reboot the device into fastboot or recovery mode. Changes in v3: - descirbe all reboot mode as properity instead of subnode - add mask value for some platform which only use some bits of the register to store boot mode magic value - add rk3036 support Changes in v2: - move to dir drivers/power/reset/ - make syscon-reboot-mode a generic driver - make this node as a subnode of PMU - make this node as a subnode of pmugrf Changes in v1: - fix the embarrassed compile warning - correct the maskrom magic number - check for the normal reboot - correct the maskrom magic number - use macro defined in rockchip_boot-mode.h for reboot-mode DT node Andy Yan (4): dt-bindings: power: reset: add document for reboot-mode driver power: reset: add reboot mode driver ARM: dts: rockchip: add syscon-reboot-mode node ARM64: dts: rockchip: add syscon-reboot-mode DT node .../bindings/power/reset/reboot-mode.txt | 26 +++++ .../bindings/power/reset/syscon-reboot-mode.txt | 36 +++++++ arch/arm/boot/dts/rk3036.dtsi | 10 +- arch/arm/boot/dts/rk3288.dtsi | 11 +++ arch/arm/boot/dts/rk3xxx.dtsi | 13 ++- arch/arm64/boot/dts/rockchip/rk3368.dtsi | 14 ++- drivers/power/reset/Kconfig | 16 ++++ drivers/power/reset/Makefile | 2 + drivers/power/reset/reboot-mode.c | 105 +++++++++++++++++++++ drivers/power/reset/reboot-mode.h | 6 ++ drivers/power/reset/syscon-reboot-mode.c | 64 +++++++++++++ include/dt-bindings/soc/rockchip_boot-mode.h | 30 ++++++ 12 files changed, 330 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/power/reset/reboot-mode.txt create mode 100644 Documentation/devicetree/bindings/power/reset/syscon-reboot-mode.txt create mode 100644 drivers/power/reset/reboot-mode.c create mode 100644 drivers/power/reset/reboot-mode.h create mode 100644 drivers/power/reset/syscon-reboot-mode.c create mode 100644 include/dt-bindings/soc/rockchip_boot-mode.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
