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 STI_RESET
bool "Enable the STi reset"
depends on ARCH_STI
help
Support for reset controllers on STMicroelectronics STiH407 family SoCs.
Say Y if you want to control reset signals provided by system config
block.
config STM32_RESET
bool "Enable the STM32 reset"
depends on ARCH_STM32 || ARCH_STM32MP
help
Support for reset controllers on STMicroelectronics STM32 family SoCs.
This reset driver is compatible with STM32 F4/F7 and H7 SoCs.
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).
config RESET_TI_SCI
bool "TI System Control Interface (TI SCI) reset driver"
depends on DM_RESET && TI_SCI_PROTOCOL
help
This enables the reset driver support over TI System Control Interface
available on some new TI's SoCs. If you wish to use reset resources
managed by the TI System Controller, say Y here. Otherwise, say N.
config RESET_BCM6345
bool "Reset controller driver for BCM6345"
depends on DM_RESET && ARCH_BMIPS
help
Support reset controller on BCM6345.
config RESET_UNIPHIER
bool "Reset controller driver for UniPhier SoCs"
depends on ARCH_UNIPHIER
default y
help
Support for reset controllers on UniPhier SoCs.
Say Y if you want to control reset signals provided by System Control
block, Media I/O block, Peripheral Block.
config AST2500_RESET
bool "Reset controller driver for AST2500 SoCs"
depends on DM_RESET && WDT_ASPEED
default y if ASPEED_AST2500
help
Support for reset controller on AST2500 SoC. This controller uses
watchdog to reset different peripherals and thus only supports
resets that are supported by watchdog. The main limitation though
is that some reset signals, like I2C or MISC reset multiple devices.
config RESET_ROCKCHIP
bool "Reset controller driver for Rockchip SoCs"
depends on DM_RESET && ARCH_ROCKCHIP && CLK
default y
help
Support for reset controller on rockchip SoC. The main limitation
though is that some reset signals, like I2C or MISC reset multiple
devices.
config RESET_HSDK
bool "Synopsys HSDK Reset Driver"
depends on DM_RESET && TARGET_HSDK
default y
help
This enables the reset controller driver for HSDK board.
config RESET_MESON
bool "Reset controller driver for Amlogic Meson SoCs"
depends on DM_RESET && ARCH_MESON
imply REGMAP
default y
help
Support for reset controller on Amlogic Meson SoC.
config RESET_SOCFPGA
bool "Reset controller driver for SoCFPGA"
depends on DM_RESET && ARCH_SOCFPGA
default y
help
Support for reset controller on SoCFPGA platform.
config RESET_MEDIATEK
bool "Reset controller driver for MediaTek SoCs"
depends on DM_RESET && ARCH_MEDIATEK && CLK
default y
help
Support for reset controller on MediaTek SoCs.
config RESET_MTMIPS
bool "Reset controller driver for MediaTek MIPS platform"
depends on DM_RESET && ARCH_MTMIPS
default y
help
Support for reset controller on MediaTek MIPS platform.
config RESET_SUNXI
bool "RESET support for Allwinner SoCs"
depends on DM_RESET && ARCH_SUNXI
default y
help
This enables support for common reset driver for
Allwinner SoCs.
config RESET_HISILICON
bool "Reset controller driver for HiSilicon SoCs"
depends on DM_RESET
help
Support for reset controller on HiSilicon SoCs.
config RESET_IMX7
bool "i.MX7/8 Reset Driver"
depends on DM_RESET && (ARCH_MX7 || ARCH_IMX8M)
default y
help
Support for reset controller on i.MX7/8 SoCs.
config RESET_SIFIVE
bool "Reset Driver for SiFive SoC's"
depends on DM_RESET && CLK_SIFIVE_FU540_PRCI && TARGET_SIFIVE_FU540
default y
help
PRCI module within SiFive SoC's provides mechanism to reset
different hw blocks like DDR, gemgxl. With this driver we leverage
U-Boot's reset framework to reset these hardware blocks.
config RESET_SYSCON
bool "Enable generic syscon reset driver support"
depends on DM_RESET
help
Support generic syscon mapped register reset devices.
config RESET_RASPBERRYPI
bool "Raspberry Pi 4 Firmware Reset Controller Driver"
depends on DM_RESET && ARCH_BCM283X
default USB_XHCI_PCI
help
Raspberry Pi 4's co-processor controls some of the board's HW
initialization process, but it's up to Linux to trigger it when
relevant. This driver provides a reset controller capable of
interfacing with RPi4's co-processor and model these firmware
initialization routines as reset lines.
