1* Sigma Designs Tango4 Clock Generator
2
3The Tango4 clock generator outputs cpu_clk and sys_clk (the latter is used
4for RAM and various peripheral devices). The clock binding described here
5is applicable to all Tango4 SoCs.
6
7Required Properties:
8
9- compatible: should be "sigma,tango4-clkgen".
10- reg: physical base address of the device and length of memory mapped region.
11- clocks: phandle of the input clock (crystal oscillator).
12- clock-output-names: should be "cpuclk" and "sysclk".
13- #clock-cells: should be set to 1.
14
15Example:
16
17	clkgen: clkgen@10000 {
18		compatible = "sigma,tango4-clkgen";
19		reg = <0x10000 0x40>;
20		clocks = <&xtal>;
21		clock-output-names = "cpuclk", "sysclk";
22		#clock-cells = <1>;
23	};
