power: reset: Add QEMU virt-ctrl driver

2026-04-13T10:16:10+00:00

Add a new driver for the 'virt-ctrl' device found on QEMU virt machines (e.g. m68k). This device provides a simple interface for system reset and power off [1]. This driver utilizes the modern system-off API to register callbacks for both system restart and power off. It also registers a reboot notifier to catch SYS_HALT events, ensuring that LINUX_REBOOT_CMD_HALT is properly handled. It is designed to be generic and can be reused by other architectures utilizing this QEMU device.

power: reset: drop unneeded dependencies on OF_GPIO

2026-04-02T22:40:09+00:00

OF_GPIO is selected automatically on all OF systems. Any symbols it controls also provide stubs so there's really no reason to select it explicitly. For Kconfig entries that have no other dependencies: convert it to requiring OF to avoid new symbols popping up for everyone in make config, for others just drop it altogether.
