menu "Reset Controller Support" config DM_RESET bool "Enable reset controllers using Driver Model" depends on DM && OF_CONTROL help Enable support for the reset controller driver class. Many hardware modules are equipped with a reset signal, typically driven by some reset controller hardware module within the chip. In U-Boot, reset controller drivers allow control over these reset signals. In some cases this API is applicable to chips outside the CPU as well, although driving such reset isgnals using GPIOs may be more appropriate in this case. config SANDBOX_RESET bool "Enable the sandbox reset test driver" depends on DM_MAILBOX && SANDBOX help Enable support for a test reset controller implementation, which simply accepts requests to reset various HW modules without actually doing anything beyond a little error checking. config TEGRA_CAR_RESET bool "Enable Tegra CAR-based reset driver" depends on TEGRA_CAR help Enable support for manipulating Tegra's on-SoC reset signals via direct register access to the Tegra CAR (Clock And Reset controller). config TEGRA186_RESET bool "Enable Tegra186 BPMP-based reset driver" depends on TEGRA186_BPMP help Enable support for manipulating Tegra's on-SoC reset signals via IPC requests to the BPMP (Boot and Power Management Processor). endmenu
