Subject: [PATCH] dt-bindings: watchdog: Convert marvell,armada-3700-wdt to DT schema
Date: Tue, 12 Aug 2025 15:32:57 -0500 [thread overview]
Message-ID: <20250812203301.726374-1-robh@kernel.org> (raw)
Convert the Marvell Armada 3700 watchdog binding to DT schema format.
It's a straight-forward conversion.

-* Armada 37xx CPU Watchdog Timer Controller
-
-Required properties:
-- compatible : must be "marvell,armada-3700-wdt"
-- reg : base physical address of the controller and length of memory mapped
- region.
-- clocks : the clock feeding the watchdog timer. See clock-bindings.txt
-- marvell,system-controller : reference to syscon node for the CPU Miscellaneous
- Registers
-
-Example:
-
- cpu_misc: system-controller@d000 {

- reg = <0xd000 0x1000>;

- reg = <0x8300 0x40>;
- marvell,system-controller = <&cpu_misc>;
- clocks = <&xtalclk>;
