1*4882a593SmuzhiyunStatus: Unstable - ABI compatibility may be broken in the future
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunBinding for Keystone gate control driver which uses PSC controller IP.
4*4882a593Smuzhiyun
5*4882a593SmuzhiyunThis binding uses the common clock binding[1].

8*4882a593Smuzhiyun
9*4882a593SmuzhiyunRequired properties:
10*4882a593Smuzhiyun- compatible : shall be "ti,keystone,psc-clock".
11*4882a593Smuzhiyun- #clock-cells : from common clock binding; shall be set to 0.
12*4882a593Smuzhiyun- clocks : parent clock phandle
13*4882a593Smuzhiyun- reg :	psc control and domain address address space
14*4882a593Smuzhiyun- reg-names : psc control and domain registers
15*4882a593Smuzhiyun- domain-id : psc domain id needed to check the transition state register
16*4882a593Smuzhiyun
17*4882a593SmuzhiyunOptional properties:
18*4882a593Smuzhiyun- clock-output-names : From common clock binding to override the
19*4882a593Smuzhiyun			default output clock name
20*4882a593SmuzhiyunExample:
21*4882a593Smuzhiyun	clkusb: clkusb {
22*4882a593Smuzhiyun		#clock-cells = <0>;
23*4882a593Smuzhiyun		compatible = "ti,keystone,psc-clock";
24*4882a593Smuzhiyun		clocks = <&chipclk16>;
25*4882a593Smuzhiyun		clock-output-names = "usb";
26*4882a593Smuzhiyun		reg = <0x02350008 0xb00>, <0x02350000 0x400>;
27*4882a593Smuzhiyun		reg-names = "control", "domain";
28*4882a593Smuzhiyun		domain-id = <0>;
