1menu "Reset Controller Support" 2 3config DM_RESET 4 bool "Enable reset controllers using Driver Model" 5 depends on DM && OF_CONTROL 6 help 7 Enable support for the reset controller driver class. Many hardware 8 modules are equipped with a reset signal, typically driven by some 9 reset controller hardware module within the chip. In U-Boot, reset 10 controller drivers allow control over these reset signals. In some 11 cases this API is applicable to chips outside the CPU as well, 12 although driving such reset isgnals using GPIOs may be more 13 appropriate in this case. 14 15config SANDBOX_RESET 16 bool "Enable the sandbox reset test driver" 17 depends on DM_MAILBOX && SANDBOX 18 help 19 Enable support for a test reset controller implementation, which 20 simply accepts requests to reset various HW modules without actually 21 doing anything beyond a little error checking. 22 23config STI_RESET 24 bool "Enable the STi reset" 25 depends on ARCH_STI 26 help 27 Support for reset controllers on STMicroelectronics STiH407 family SoCs. 28 Say Y if you want to control reset signals provided by system config 29 block. 30 31config TEGRA_CAR_RESET 32 bool "Enable Tegra CAR-based reset driver" 33 depends on TEGRA_CAR 34 help 35 Enable support for manipulating Tegra's on-SoC reset signals via 36 direct register access to the Tegra CAR (Clock And Reset controller). 37 38config TEGRA186_RESET 39 bool "Enable Tegra186 BPMP-based reset driver" 40 depends on TEGRA186_BPMP 41 help 42 Enable support for manipulating Tegra's on-SoC reset signals via IPC 43 requests to the BPMP (Boot and Power Management Processor). 44 45config RESET_UNIPHIER 46 bool "Reset controller driver for UniPhier SoCs" 47 depends on ARCH_UNIPHIER 48 default y 49 help 50 Support for reset controllers on UniPhier SoCs. 51 Say Y if you want to control reset signals provided by System Control 52 block, Media I/O block, Peripheral Block. 53 54config AST2500_RESET 55 bool "Reset controller driver for AST2500 SoCs" 56 depends on DM_RESET && WDT_ASPEED 57 default y if ASPEED_AST2500 58 help 59 Support for reset controller on AST2500 SoC. This controller uses 60 watchdog to reset different peripherals and thus only supports 61 resets that are supported by watchdog. The main limitation though 62 is that some reset signals, like I2C or MISC reset multiple devices. 63 64endmenu 65
