I still can not parse this note. The MAINTAINERS entry for watchdog devices
includes
F: Documentation/devicetree/bindings/watchdog/
F: drivers/watchdog/
which should cover both the old and the new bindings as well as the driver.
Please explain.

I don't mind placing you and Wim into the yaml DT maintainer section if
that's OK with you ?

Ah, you mean the _yaml_ Maintainer entry. Just add me; I can not make
the call for Wim.

Yes, that entry. That's what I was wondering about.
I'll wait a bit before sending V3.

Where do you get that Cc: list from anyway ? get_maintainer.pl on both the
mainline kernel and on linux-next tells me
Wim Van Sebroeck <wim@linux-watchdog.org> (maintainer:WATCHDOG DEVICE DRIVERS)
Guenter Roeck <linux@roeck-us.net> (maintainer:WATCHDOG DEVICE DRIVERS)
Rob Herring <robh+dt@kernel.org> (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
Krzysztof Kozlowski <krzysztof.kozlowski+dt@linaro.org> (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)

devicetree@vger.kernel.org (open list:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
linux-kernel@vger.kernel.org (open list)
Why don't you copy Krzysztof ?

Convert the gpio-wdt bindings from text to YAML ones, to permit DT validation.

V2: - Add missing required: properties
- Drop quotes around ref: referenced schema file name

NOTE: The Maintainer entry should likely be changed, although it seems
like this driver and its matching bindings are now unmaintained.

-* GPIO-controlled Watchdog
-
-Required Properties:
-- compatible: Should contain "linux,wdt-gpio".
-- gpios: From common gpio binding; gpio connection to WDT reset pin.
-- hw_algo: The algorithm used by the driver. Should be one of the
- following values:
- - toggle: Either a high-to-low or a low-to-high transition clears
- the WDT counter. The watchdog timer is disabled when GPIO is
- left floating or connected to a three-state buffer.
- - level: Low or high level starts counting WDT timeout,
- the opposite level disables the WDT. Active level is determined
- by the GPIO flags.
-- hw_margin_ms: Maximum time to reset watchdog circuit (milliseconds).
-
-Optional Properties:
-- always-running: If the watchdog timer cannot be disabled, add this flag to
- have the driver keep toggling the signal without a client. It will only cease
- to toggle the signal when the device is open and the timeout elapsed.
-
-Example:
- watchdog: watchdog {
- /* ADM706 */
- compatible = "linux,wdt-gpio";
- gpios = <&gpio3 9 GPIO_ACTIVE_LOW>;
- hw_algo = "toggle";
- hw_margin_ms = <1600>;
