1 * Amlogic GXBB AO Clock and Reset Unit
3 The Amlogic GXBB AO clock controller generates and supplies clock to various
4 controllers within the Always-On part of the SoC.
8 - compatible: value should be different for each SoC family as :
9 	- GXBB (S905) : "amlogic,meson-gxbb-aoclkc"
10 	- GXL (S905X, S905D) : "amlogic,meson-gxl-aoclkc"
11 	- GXM (S912) : "amlogic,meson-gxm-aoclkc"
12 	- AXG (A113D, A113X) : "amlogic,meson-axg-aoclkc"
13 	- G12A (S905X2, S905D2, S905Y2) : "amlogic,meson-g12a-aoclkc"
14 	followed by the common "amlogic,meson-gx-aoclkc"
15 - clocks: list of clock phandle, one for each entry clock-names.
16 - clock-names: should contain the following:
17   * "xtal"     : the platform xtal
18   * "mpeg-clk" : the main clock controller mother clock (aka clk81)
19   * "ext-32k-0"  : external 32kHz reference #0 if any (optional)
20   * "ext-32k-1"  : external 32kHz reference #1 if any (optional - gx only)
21   * "ext-32k-2"  : external 32kHz reference #2 if any (optional - gx only)
23 - #clock-cells: should be 1.
25 Each clock is assigned an identifier and client nodes can use this identifier
26 to specify the clock which they consume. All available clocks are defined as
27 preprocessor macros in the dt-bindings/clock/gxbb-aoclkc.h header and can be
30 - #reset-cells: should be 1.
34 preprocessor macros in the dt-bindings/reset/gxbb-aoclkc.h header and can be
38 - compatible: "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd"
39 - reg: base address and size of the AO system control register space.
41 Example: AO Clock controller node:
43 ao_sysctrl: sys-ctrl@0 {
44 	compatible = "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd";
47 	clkc_AO: clock-controller {
48 		compatible = "amlogic,meson-gxbb-aoclkc", "amlogic,meson-gx-aoclkc";
49 		#clock-cells = <1>;
50 		#reset-cells = <1>;
51 		clocks = <&xtal>, <&clkc CLKID_CLK81>;
52 		clock-names = "xtal", "mpeg-clk";
55 Example: UART controller node that consumes the clock and reset generated
56   by the clock controller:
59 		compatible = "amlogic,meson-uart";
