1*4882a593SmuzhiyunBinding for Texas Instruments clockdomain.
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunBinding status: Unstable - ABI compatibility may be broken in the future
4*4882a593Smuzhiyun
5*4882a593SmuzhiyunThis binding uses the common clock binding[1] in consumer role.
6*4882a593SmuzhiyunEvery clock on TI SoC belongs to one clockdomain, but software
7*4882a593Smuzhiyunonly needs this information for specific clocks which require
8*4882a593Smuzhiyuntheir parent clockdomain to be controlled when the clock is
9*4882a593Smuzhiyunenabled/disabled. This binding doesn't define a new clock
10*4882a593Smuzhiyunbinding type, it is used to group existing clock nodes under
11*4882a593Smuzhiyunhardware hierarchy.

14*4882a593Smuzhiyun
15*4882a593SmuzhiyunRequired properties:
16*4882a593Smuzhiyun- compatible : shall be "ti,clockdomain"
17*4882a593Smuzhiyun- #clock-cells : from common clock binding; shall be set to 0.
18*4882a593Smuzhiyun- clocks : link phandles of clocks within this domain
19*4882a593Smuzhiyun
20*4882a593SmuzhiyunExamples:
21*4882a593Smuzhiyun	dss_clkdm: dss_clkdm {
22*4882a593Smuzhiyun		compatible = "ti,clockdomain";
23*4882a593Smuzhiyun		clocks = <&dss1_alwon_fck_3430es2>, <&dss_ick_3430es2>;
