1 Ingenic SoC CGU binding
3 The CGU in an Ingenic SoC provides all the clocks generated on-chip. It
4 typically includes a variety of PLLs, multiplexers, dividers & gates in order
5 to provide many different clock signals derived from only 2 external source
9 - compatible : Should be one of:
14 - reg : The address & length of the CGU registers.
15 - clocks : List of phandle & clock specifiers for clocks external to the CGU.
16 Two such external clocks should be specified - first the external crystal
17 "ext" and second the RTC clock source "rtc".
18 - clock-names : List of name strings for the external clocks.
19 - #clock-cells: Should be 1.
20 Clock consumers specify this argument to identify a clock. The valid values
21 may be found in <dt-bindings/clock/<soctype>-cgu.h>.
23 Example SoC include file:
27 compatible = "ingenic,jz4740-cgu";
28 reg = <0x10000000 0x100>;
32 uart0: serial@10030000 {
33 clocks = <&cgu JZ4740_CLK_UART0>;
41 compatible = "fixed-clock";
43 clock-frequency = <12000000>;
47 compatible = "fixed-clock";
49 clock-frequency = <32768>;
53 clocks = <&ext> <&rtc>;
54 clock-names: "ext", "rtc";
