Xiaoliang Yang da4918acb8 watchdog: imx: add config to disable wdog reset
Add Kconfig option WATCHDOG_RESET_DISABLE to disable watchdog reset
in imx_watchdog driver, so that the watchdog will not be fed in
u-boot if CONFIG_WATCHDOG_RESET_DISABLE is enabled.

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 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 TANGIER_WATCHDOG
bool "Intel Tangier watchdog"
depends on INTEL_MID
select HW_WATCHDOG
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 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
help
Enable driver model for watchdog timer. At the moment the API
is very simple and only supports four operations:
start, restart, stop and reset (expire immediately).
What exactly happens when the timer expires is up to a particular
device/driver.
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_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_BCM6345
bool "BCM6345 watchdog timer support"
depends on WDT && ARCH_BMIPS
help
Select this to enable watchdog timer for BCM6345 SoCs.
The watchdog timer is stopped when initialized.
It performs full SoC reset.

bool "Orion watchdog timer support"
depends on WDT
help
Select this to enable Orion watchdog timer, which can be found on some
Marvell Armada chips.
config WDT_CDNS
bool "Cadence watchdog timer support"
depends on WDT
