Many hardware 889c1e2daSStephen Warren modules are equipped with a reset signal, typically driven by some 989c1e2daSStephen Warren reset controller hardware module within the chip. In U-Boot, reset 1089c1e2daSStephen Warren controller drivers allow control over these reset signals. In some 1189c1e2daSStephen Warren cases this API is applicable to chips outside the CPU as well, 1289c1e2daSStephen Warren although driving such reset isgnals using GPIOs may be more 1389c1e2daSStephen Warren appropriate in this case. 1489c1e2daSStephen Warren 154581b717SStephen Warrenconfig SANDBOX_RESET 164581b717SStephen Warren bool "Enable the sandbox reset test driver" 174581b717SStephen Warren depends on DM_MAILBOX && SANDBOX 184581b717SStephen Warren help 194581b717SStephen Warren Enable support for a test reset controller implementation, which 204581b717SStephen Warren simply accepts requests to reset various HW modules without actually 214581b717SStephen Warren doing anything beyond a little error checking. 224581b717SStephen Warren 23584861ffSPatrice Chotardconfig STI_RESET 24584861ffSPatrice Chotard bool "Enable the STi reset" 25584861ffSPatrice Chotard depends on ARCH_STI 26584861ffSPatrice Chotard help 27584861ffSPatrice Chotard Support for reset controllers on STMicroelectronics STiH407 family SoCs. 28584861ffSPatrice Chotard Say Y if you want to control reset signals provided by system config 29584861ffSPatrice Chotard block. 30584861ffSPatrice Chotard 31fe60f06dSStephen Warrenconfig TEGRA_CAR_RESET 32fe60f06dSStephen Warren bool "Enable Tegra CAR-based reset driver" 33fe60f06dSStephen Warren depends on TEGRA_CAR 34fe60f06dSStephen Warren help 35fe60f06dSStephen Warren Enable support for manipulating Tegra's on-SoC reset signals via 36fe60f06dSStephen Warren direct register access to the Tegra CAR (Clock And Reset controller). 37fe60f06dSStephen Warren 384dd99d14SStephen Warrenconfig TEGRA186_RESET 394dd99d14SStephen Warren bool "Enable Tegra186 BPMP-based reset driver" 404dd99d14SStephen Warren depends on TEGRA186_BPMP 414dd99d14SStephen Warren help 424dd99d14SStephen Warren Enable support for manipulating Tegra's on-SoC reset signals via IPC 434dd99d14SStephen Warren requests to the BPMP (Boot and Power Management Processor). 444dd99d14SStephen Warren 454fb96c48SMasahiro Yamadaconfig RESET_UNIPHIER 464fb96c48SMasahiro Yamada bool "Reset controller driver for UniPhier SoCs" 474fb96c48SMasahiro Yamada depends on ARCH_UNIPHIER 484fb96c48SMasahiro Yamada default y 494fb96c48SMasahiro Yamada help 504fb96c48SMasahiro Yamada Support for reset controllers on UniPhier SoCs. 514fb96c48SMasahiro Yamada Say Y if you want to control reset signals provided by System Control 524fb96c48SMasahiro Yamada block, Media I/O block, Peripheral Block. 534fb96c48SMasahiro Yamada 54*858d4976Smaxims@google.comconfig AST2500_RESET 55*858d4976Smaxims@google.com bool "Reset controller driver for AST2500 SoCs" 56*858d4976Smaxims@google.com depends on DM_RESET && WDT_ASPEED 57*858d4976Smaxims@google.com default y if ASPEED_AST2500 58*858d4976Smaxims@google.com help 59*858d4976Smaxims@google.com Support for reset controller on AST2500 SoC.
