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.

749c9aae9d drivers: watchdog: add a DM driver for the MPC8xx watchdog
This patch adds a DM driver for the MPC8xx watchdog.
Basically, the watchdog is enabled by default from the start and
SYPCR register has to be writen once to set the timeout and/or
deactivate the watchdog. Once written, it cannot be written again.

It means that wdt_stop() can be called before wdt_start() to stop the
watchdog, but cannot be called if wdt_start() has been called.

2b69a67389 watchdog: Add support for Armada 37xx CPU watchdog
This adds support for the CPU watchdog found on Marvell Armada 37xx
SoCs.

There are 4 counters which can be set as CPU watchdog counters.
This driver uses the second counter (ID 1, counting from 0)
(Marvell's Linux also uses second counter by default).
In the future it could be adapted to use other counters, with
definition in the device tree.

2ab7704a6d orion_wdt: Support for the Orion Watchdog
The Orion watchdog can be found on some Marvell Armada chips.

This driver is based on the code by Tomas Hlavacek in the CZ.NIC
turris-omnia-uboot repository, which can be found at
https://gitlab.labs.nic.cz/turris/turris-omnia-uboot, and that
one is based on code by Sylver Bruneau. His code is already in
mainline Linux kernel.

The code uses the new driver model API.

it is currently only enabled by default on AM33XX, so keep that logic
