maxims@google.com 858d497629 aspeed: Reset Driver
Add Reset Driver for ast2500 SoC. This driver uses Watchdog Timer to
perform resets and thus depends on it. The actual Watchdog device used
needs to be configured in Device Tree using "aspeed,wdt" property, which
must be WDT phandle, for example:

rst: reset-controller {
    compatible = "aspeed,ast2500-reset";
    aspeed,wdt = <&wdt1>;
}

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 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_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.
