menu "Watchdog Timer Support"
config WATCHDOG
bool "Enable U-Boot watchdog reset"
help
This option enables U-Boot watchdog support where U-Boot is using
watchdog_reset function to service watchdog device in U-Boot. Enable
this option if you want to service enabled watchdog by U-Boot. Disable
this option if you want U-Boot to start watchdog but never service it.
config HW_WATCHDOG
bool
config WATCHDOG_RESET_DISABLE
bool "Disable reset watchdog"
help
Disable reset watchdog, which can let WATCHDOG_RESET invalid, so
that the watchdog will not be fed in u-boot.
config BCM2835_WDT
bool "Enable BCM2835/2836 watchdog driver"
select HW_WATCHDOG
help
Say Y here to enable the BCM2835/2836 watchdog
This provides basic infrastructure to support BCM2835/2836 watchdog
hardware, with a max timeout of ~15secs.
config IMX_WATCHDOG
bool "Enable Watchdog Timer support for IMX and LSCH2 of NXP"
select HW_WATCHDOG if !WDT
help
Select this to enable the IMX and LSCH2 of Layerscape watchdog
driver.
config OMAP_WATCHDOG
bool "TI OMAP watchdog driver"
depends on ARCH_OMAP2PLUS
select HW_WATCHDOG
default y if AM33XX
help
Say Y here to enable the OMAP3+ watchdog driver.
config ULP_WATCHDOG
bool "i.MX7ULP watchdog"
help
Say Y here to enable i.MX7ULP watchdog driver.
config WDT
bool "Enable driver model for watchdog timer drivers"
depends on DM
imply WATCHDOG
help
Enable driver model for watchdog timer. At the moment the API
is very simple and only supports four operations:
start, stop, reset and expire_now (expire immediately).
What exactly happens when the timer expires is up to a particular
device/driver.
config WDT_ARMADA_37XX
bool "Marvell Armada 37xx watchdog timer support"
depends on WDT && ARMADA_3700
help
Enable this to support Watchdog Timer on Marvell Armada 37xx SoC.
There are 4 possible clocks which can be used on these SoCs. This
driver uses the second clock (ID 1), assuming that so will also
Linux's driver.
config WDT_ASPEED
bool "Aspeed ast2400/ast2500 watchdog timer support"
depends on WDT
default y if ARCH_ASPEED
help
Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices.
The watchdog timer is stopped when initialized. It performs reset, either
full SoC reset or CPU or just some peripherals, based on the flags.
It currently does not support Boot Flash Addressing Mode Detection or
Second Boot.
config WDT_AT91
bool "AT91 watchdog timer support"
depends on WDT
help
Select this to enable Microchip watchdog timer, which can be found on
some AT91 devices.
config WDT_BCM6345
bool "BCM6345 watchdog timer support"
depends on WDT && (ARCH_BMIPS || ARCH_BCM6858 || ARCH_BCM63158)
help
Select this to enable watchdog timer for BCM6345 SoCs.
The watchdog timer is stopped when initialized.
It performs full SoC reset.
config WDT_CDNS
bool "Cadence watchdog timer support"
depends on WDT
imply WATCHDOG
help
Select this to enable Cadence watchdog timer, which can be found on some
Xilinx Microzed Platform.
config WDT_MPC8xx
bool "MPC8xx watchdog timer support"
depends on WDT && MPC8xx
select CONFIG_MPC8xx_WATCHDOG
help
Select this to enable mpc8xx watchdog timer
config WDT_MT7621
bool "MediaTek MT7621 watchdog timer support"
depends on WDT && SOC_MT7628
help
Select this to enable Ralink / Mediatek watchdog timer,
which can be found on some MediaTek chips.
config WDT_MTK
bool "MediaTek watchdog timer support"
depends on WDT && ARCH_MEDIATEK
help
Select this to enable watchdog timer for MediaTek SoCs.
The watchdog timer is stopped when initialized.
It performs full SoC reset.
config WDT_ORION
bool "Orion watchdog timer support"
depends on WDT
select CLK
help
Select this to enable Orion watchdog timer, which can be found on some
Marvell Armada chips.
config WDT_SANDBOX
bool "Enable Watchdog Timer support for Sandbox"
depends on SANDBOX && WDT
help
Enable Watchdog Timer support in Sandbox. This is a dummy device that
can be probed and supports all of the methods of WDT, but does not
really do anything.
config WDT_SP805
bool "SP805 watchdog timer support"
depends on WDT
help
Select this to enable SP805 watchdog timer, which can be found on some
nxp layerscape chips.
config WDT_STM32MP
bool "IWDG watchdog driver for STM32 MP's family"
depends on WDT
imply WATCHDOG
help
Enable the STM32 watchdog (IWDG) driver. Enable support to
configure STM32's on-SoC watchdog.
config XILINX_TB_WATCHDOG
bool "Xilinx Axi watchdog timer support"
depends on WDT
imply WATCHDOG
help
Select this to enable Xilinx Axi watchdog timer, which can be found on some
Xilinx Microblaze Platforms.
config WDT_TANGIER
bool "Intel Tangier watchdog timer support"
depends on WDT && INTEL_MID
help
This enables support for watchdog controller available on
Intel Tangier SoC. If you're using a board with Intel Tangier
SoC, say Y here.
config SPL_WDT
bool "Enable driver model for watchdog timer drivers in SPL"
depends on SPL_DM
help
Enable driver model for watchdog timer in SPL.
This is similar to CONFIG_WDT in U-Boot.
