-* Amlogic GXBB AO Clock and Reset Unit
-
-The Amlogic GXBB AO clock controller generates and supplies clock to various
-controllers within the Always-On part of the SoC.
-
-Required Properties:
-
-- compatible: value should be different for each SoC family as :
- - GXBB (S905) : "amlogic,meson-gxbb-aoclkc"
- - GXL (S905X, S905D) : "amlogic,meson-gxl-aoclkc"
- - GXM (S912) : "amlogic,meson-gxm-aoclkc"
- - AXG (A113D, A113X) : "amlogic,meson-axg-aoclkc"
- - G12A (S905X2, S905D2, S905Y2) : "amlogic,meson-g12a-aoclkc"
- followed by the common "amlogic,meson-gx-aoclkc"
-- clocks: list of clock phandle, one for each entry clock-names.
-- clock-names: should contain the following:
- * "xtal" : the platform xtal
- * "mpeg-clk" : the main clock controller mother clock (aka clk81)
- * "ext-32k-0" : external 32kHz reference #0 if any (optional)
- * "ext-32k-1" : external 32kHz reference #1 if any (optional - gx only)
- * "ext-32k-2" : external 32kHz reference #2 if any (optional - gx only)
-
-- #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/gxbb-aoclkc.h header and can be
-used in device tree sources.
-
-- #reset-cells: should be 1.
-
-Each reset is assigned an identifier and client nodes can use this identifier
-to specify the reset which they consume. All available resets are defined as
-preprocessor macros in the dt-bindings/reset/gxbb-aoclkc.h header and can be
-used in device tree sources.
-
-Parent node should have the following properties :
-- compatible: "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd"
-- reg: base address and size of the AO system control register space.
-
-Example: AO Clock controller node:
-
-ao_sysctrl: sys-ctrl@0 {
- compatible = "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd";
- reg = <0x0 0x0 0x0 0x100>;
-
- clkc_AO: clock-controller {
- compatible = "amlogic,meson-gxbb-aoclkc", "amlogic,meson-gx-aoclkc";
- #clock-cells = <1>;
- #reset-cells = <1>;
- clocks = <&xtal>, <&clkc CLKID_CLK81>;
- clock-names = "xtal", "mpeg-clk";
- };
-
-Example: UART controller node that consumes the clock and reset generated
- by the clock controller:
-
- uart_AO: serial@4c0 {
- compatible = "amlogic,meson-uart";
- reg = <0x4c0 0x14>;
- interrupts = <0 90 1>;
- clocks = <&clkc_AO CLKID_AO_UART1>;
- resets = <&clkc_AO RESET_AO_UART1>;
- };
