-Device Tree Clock bindings for arch-sunxi
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : shall be one of the following:
- "allwinner,sun4i-osc-clk" - for a gatable oscillator
- "allwinner,sun4i-pll1-clk" - for the main PLL clock
- "allwinner,sun4i-cpu-clk" - for the CPU multiplexer clock
- "allwinner,sun4i-axi-clk" - for the AXI clock
- "allwinner,sun4i-axi-gates-clk" - for the AXI gates
- "allwinner,sun4i-ahb-clk" - for the AHB clock
- "allwinner,sun4i-ahb-gates-clk" - for the AHB gates on A10
- "allwinner,sun5i-a13-ahb-gates-clk" - for the AHB gates on A13
- "allwinner,sun4i-apb0-clk" - for the APB0 clock
- "allwinner,sun4i-apb0-gates-clk" - for the APB0 gates on A10
- "allwinner,sun5i-a13-apb0-gates-clk" - for the APB0 gates on A13
- "allwinner,sun4i-apb1-clk" - for the APB1 clock
- "allwinner,sun4i-apb1-mux-clk" - for the APB1 clock muxing
- "allwinner,sun4i-apb1-gates-clk" - for the APB1 gates on A10
- "allwinner,sun5i-a13-apb1-gates-clk" - for the APB1 gates on A13
-
-Required properties for all clocks:
-- reg : shall be the control register address for the clock.
-- clocks : shall be the input parent clock(s) phandle for the clock
-- #clock-cells : from common clock binding; shall be set to 0 except for
- "allwinner,*-gates-clk" where it shall be set to 1
-
-Additionally, "allwinner,*-gates-clk" clocks require:
-- clock-output-names : the corresponding gate names that the clock controls
-
-Clock consumers should specify the desired clocks they use with a
-"clocks" phandle cell. Consumers that are using a gated clock should
-provide an additional ID in their clock property. The values of this
-ID are documented in sunxi/<soc>-gates.txt.
-
-For example:
-
-osc24M: osc24M@01c20050 {
- #clock-cells = <0>;
- compatible = "allwinner,sun4i-osc-clk";
- reg = <0x01c20050 0x4>;
- clocks = <&osc24M_fixed>;
-};
-
-pll1: pll1@01c20000 {
- #clock-cells = <0>;
- compatible = "allwinner,sun4i-pll1-clk";
- reg = <0x01c20000 0x4>;
- clocks = <&osc24M>;
-};
-
-cpu: cpu@01c20054 {
- #clock-cells = <0>;
- compatible = "allwinner,sun4i-cpu-clk";
- reg = <0x01c20054 0x4>;
- clocks = <&osc32k>, <&osc24M>, <&pll1>;
-};
