Merge tag 'devicetree-for-6.2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull more devicetree updates from Rob Herring:
 "This is mostly a treewide clean-up from Krzysztof. There's also a
  couple of fixes and things that fell thru the cracks.

  I must say this has been a nice merge window without bindings dumped
  in at the last minute introducing warnings.

  Summary:

   - Treewide dropping of redundant 'binding' or 'schema' from schema
     titles. This will be followed up with a automated check to catch
     these.

   - Re-sort vendor-prefies

   - Convert GPIO based watchdog to schema

   - Handle all the variations for clocks, resets, power domains in i.MX
     PCIe binding

   - Document missing 'power-domains' property in mxsfb

   - Fix error with path references in Tegra XUSB example

   - Honor CONFIG_CMDLINE* even without /chosen node"

-* 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>;
-	};
