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_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_MSM bool "Qualcomm MSM power-off driver" depends on POWER_RESET && ARCH_MSM help Power off and restart support for Qualcomm boards. 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_VEXPRESS bool "ARM Versatile Express power-off and reset driver" depends on ARM || ARM64 depends on POWER_RESET 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.
