Subject: [PATCH] dt-bindings: pinctrl: Convert marvell,armada-3710-(sb|nb)-pinctrl to DT schema
Date: Wed, 24 Sep 2025 17:35:24 -0500	[thread overview]
Message-ID: <20250924223528.2956771-1-robh@kernel.org> (raw)

Convert the marvell,armada3710-(sb|nb)-pinctrl binding to DT schema
format. The binding includes the "marvell,armada-3700-xtal-clock"
subnode which is simple enough to include here.

-* Xtal Clock bindings for Marvell Armada 37xx SoCs
-
-Marvell Armada 37xx SoCs allow to determine the xtal clock frequencies by
-reading the gpio latch register.
-
-This node must be a subnode of the node exposing the register address
-of the GPIO block where the gpio latch is located.
-See Documentation/devicetree/bindings/pinctrl/marvell,armada-37xx-pinctrl.txt
-
-Required properties:
-- compatible : shall be one of the following:
-	"marvell,armada-3700-xtal-clock"
-- #clock-cells : from common clock binding; shall be set to 0
-
-Optional properties:
-- clock-output-names : from common clock binding; allows overwrite default clock
-	output names ("xtal")
-
-Example:
-pinctrl_nb: pinctrl-nb@13800 {
-	compatible = "armada3710-nb-pinctrl", "syscon", "simple-mfd";
-	reg = <0x13800 0x100>, <0x13C00 0x20>;
-
-	xtalclk: xtal-clk {
-		compatible = "marvell,armada-3700-xtal-clock";
-		clock-output-names = "xtal";
-		#clock-cells = <0>;
-	};
