-* Amlogic GXBB Clock and Reset Unit
-
-The Amlogic GXBB clock controller generates and supplies clock to various
-controllers within the SoC.
-
-Required Properties:
-
-- compatible: should be:
- "amlogic,gxbb-clkc" for GXBB SoC,
- "amlogic,gxl-clkc" for GXL and GXM SoC,
- "amlogic,axg-clkc" for AXG SoC.
- "amlogic,g12a-clkc" for G12A SoC.
- "amlogic,g12b-clkc" for G12B SoC.
- "amlogic,sm1-clkc" for SM1 SoC.
-- clocks : list of clock phandle, one for each entry clock-names.
-- clock-names : should contain the following:
- * "xtal": the platform xtal
-
-- #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-clkc.h header and can be
-used in device tree sources.
-
-Parent node should have the following properties :
-- compatible: "syscon", "simple-mfd, and "amlogic,meson-gx-hhi-sysctrl" or
- "amlogic,meson-axg-hhi-sysctrl"
-- reg: base address and size of the HHI system control register space.
-
-Example: Clock controller node:
-
-sysctrl: system-controller@0 {
- compatible = "amlogic,meson-gx-hhi-sysctrl", "syscon", "simple-mfd";
- reg = <0 0 0 0x400>;
-
- clkc: clock-controller {
- #clock-cells = <1>;
- compatible = "amlogic,gxbb-clkc";
- clocks = <&xtal>;
- clock-names = "xtal";
- };
-};
-
-Example: UART controller node that consumes the clock generated by the clock
- controller:
-
- uart_AO: serial@c81004c0 {
- compatible = "amlogic,meson-uart";
- reg = <0xc81004c0 0x14>;
- interrupts = <0 90 1>;
- clocks = <&clkc CLKID_CLK81>;
- };
