[PATCH v2 5/6] dt-bindings: clock: add meson axg audio clock controller bindings
From: Jerome Brunet
Date: Tue May 22 2018 - 11:43:16 EST
Export the clock ids dt-bindings usable by the consumers of the clock
controller and add the documentation for the device tree bindings of
the audio clock controller of the A113 based SoCs.

+* Amlogic AXG Audio Clock Controllers
+
+The Amlogic AXG audio clock controller generates and supplies clock to the
+other elements of the audio subsystem, such as fifos, i2s, spdif and pdm
+devices.
+
+Required Properties:
+
+- compatible : should be "amlogic,axg-audio-clkc" for the A113X and A113D
+- reg : physical base address of the clock controller and length of
+ memory mapped region.
+- clocks : a list of phandle + clock-specifier pairs for the clocks listed
+ in clock-names.
+- clock-names : must contain the following:
+ * "pclk" - Main peripheral bus clock
+ may contain the following:
+ * "mst_in[0-7]" - 8 input plls to generate clock signals
+ * "slv_sclk[0-9]" - 10 slave bit clocks provided by external
+ components.
+ * "slv_lrclk[0-9]" - 10 slave sample clocks provided by external
+ components.
+- resets : phandle of the internal reset line
+- #clock-cells : should be 1.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/axg-audio-clkc.h header and can be
+used in device tree sources.
+
+Example:
+
+clkc_audio: clock-controller@0 {
+ compatible = "amlogic,axg-audio-clkc";
+ reg = <0x0 0x0 0x0 0xb4>;
+ #clock-cells = <1>;
+
+ clocks = <&clkc CLKID_AUDIO>,
+ <&clkc CLKID_MPLL0>,
+ <&clkc CLKID_MPLL1>,
+ <&clkc CLKID_MPLL2>,
+ <&clkc CLKID_MPLL3>,
+ <&clkc CLKID_HIFI_PLL>,
+ <&clkc CLKID_FCLK_DIV3>,
+ <&clkc CLKID_FCLK_DIV4>,
+ <&clkc CLKID_GP0_PLL>;
+ clock-names = "pclk",
+ "mst_in0",
+ "mst_in1",
+ "mst_in2",
+ "mst_in3",
+ "mst_in4",
+ "mst_in5",
+ "mst_in6",
+ "mst_in7";
+ resets = <&reset RESET_AUDIO>;
+};
