1*4882a593Smuzhiyun* Sigma Designs Tango4 Clock Generator
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe Tango4 clock generator outputs cpu_clk and sys_clk (the latter is used
4*4882a593Smuzhiyunfor RAM and various peripheral devices). The clock binding described here
5*4882a593Smuzhiyunis applicable to all Tango4 SoCs.
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunRequired Properties:
8*4882a593Smuzhiyun
9*4882a593Smuzhiyun- compatible: should be "sigma,tango4-clkgen".
10*4882a593Smuzhiyun- reg: physical base address of the device and length of memory mapped region.
11*4882a593Smuzhiyun- clocks: phandle of the input clock (crystal oscillator).
12*4882a593Smuzhiyun- clock-output-names: should be "cpuclk" and "sysclk".
13*4882a593Smuzhiyun- #clock-cells: should be set to 1.

15*4882a593SmuzhiyunExample:
16*4882a593Smuzhiyun
17*4882a593Smuzhiyun	clkgen: clkgen@10000 {
18*4882a593Smuzhiyun		compatible = "sigma,tango4-clkgen";
19*4882a593Smuzhiyun		reg = <0x10000 0x40>;
20*4882a593Smuzhiyun		clocks = <&xtal>;
21*4882a593Smuzhiyun		clock-output-names = "cpuclk", "sysclk";
22*4882a593Smuzhiyun		#clock-cells = <1>;
23*4882a593Smuzhiyun	};
