Subject: [PATCH] dt-bindings: clock: Convert marvell,mvebu-core-clock to DT schema
Date: Wed, 21 May 2025 16:08:43 -0500 [thread overview]
Message-ID: <20250521210844.62613-1-robh@kernel.org> (raw)
Convert the Marvell SoC core clock binding to DT schema format. It's a
straight forward conversion.

-- reg : shall be the register address of the Sample-At-Reset (SAR) register
-- #clock-cells : from common clock binding; shall be set to 1
-
-Optional properties:
-- clock-output-names : from common clock binding; allows overwrite default clock
- output names ("tclk", "cpuclk", "l2clk", "ddrclk")
-
-Example:
-
-core_clk: core-clocks@d0214 {
- compatible = "marvell,dove-core-clock";
- reg = <0xd0214 0x4>;
- #clock-cells = <1>;
-};
-
-spi0: spi@10600 {
- compatible = "marvell,orion-spi";
- /* ... */
- /* get tclk from core clock provider */
- clocks = <&core_clk 0>;
-};
