menuconfig POWER_RESET bool "Board level reset or power off" help Provides a number of drivers which either reset a complete board or shut it down, by manipulating the main power supply on the board. Say Y here to enable board reset and power off config POWER_RESET_AS3722 bool "ams AS3722 power-off driver" depends on MFD_AS3722 && POWER_RESET help This driver supports turning off board via a ams AS3722 power-off. config POWER_RESET_AXXIA bool "LSI Axxia reset driver" depends on POWER_RESET && ARCH_AXXIA help This driver supports restart for Axxia SoC. Say Y if you have an Axxia family SoC. config POWER_RESET_BRCMSTB bool "Broadcom STB reset driver" if COMPILE_TEST depends on POWER_RESET && ARM default ARCH_BRCMSTB help This driver provides restart support for ARM-based Broadcom STB boards. Say Y here if you have an ARM-based Broadcom STB board and you wish to have restart support. config POWER_RESET_GPIO bool "GPIO power-off driver" depends on OF_GPIO && POWER_RESET help This driver supports turning off your board via a GPIO line. If your board needs a GPIO high/low to power down, say Y and create a binding in your devicetree. config POWER_RESET_GPIO_RESTART bool "GPIO restart driver" depends on OF_GPIO && POWER_RESET help This driver supports restarting your board via a GPIO line. If your board needs a GPIO high/low to restart, say Y and create a binding in your devicetree. config POWER_RESET_HISI bool "Hisilicon power-off driver" depends on POWER_RESET && ARCH_HISI help Reboot support for Hisilicon boards. config POWER_RESET_MSM bool "Qualcomm MSM power-off driver" depends on POWER_RESET && ARCH_QCOM help Power off and restart support for Qualcomm boards. config POWER_RESET_LTC2952 bool "LTC2952 PowerPath power-off driver" depends on OF_GPIO && POWER_RESET help This driver supports an external powerdown trigger and board power down via the LTC2952. Bindings are made in the device tree. config POWER_RESET_QNAP bool "QNAP power-off driver" depends on OF_GPIO && POWER_RESET && PLAT_ORION help This driver supports turning off QNAP NAS devices by sending commands to the microcontroller which controls the main power. Say Y if you have a QNAP NAS. config POWER_RESET_RESTART bool "Restart power-off driver" depends on ARM help Some boards don't actually have the ability to power off. Instead they restart, and u-boot holds the SoC until the user presses a key. u-boot then boots into Linux. config POWER_RESET_SUN6I bool "Allwinner A31 SoC reset driver" depends on ARCH_SUNXI depends on POWER_RESET help Reboot support for the Allwinner A31 SoCs. config POWER_RESET_ST bool "ST restart power-off driver" depends on POWER_RESET && ARCH_STI help Power off and reset support for STMicroelectronics boards. config POWER_RESET_VEXPRESS bool "ARM Versatile Express power-off and reset driver" depends on ARM || ARM64 depends on POWER_RESET && VEXPRESS_CONFIG help Power off and reset support for the ARM Ltd. Versatile Express boards. config POWER_RESET_XGENE bool "APM SoC X-Gene reset driver" depends on ARM64 depends on POWER_RESET help Reboot support for the APM SoC X-Gene Eval boards. config POWER_RESET_KEYSTONE bool "Keystone reset driver" depends on ARCH_KEYSTONE select MFD_SYSCON help Reboot support for the KEYSTONE SoCs. config POWER_RESET_SYSCON bool "Generic SYSCON regmap reset driver" depends on POWER_RESET && OF select MFD_SYSCON help Reboot support for generic SYSCON mapped register reset.
