1*4882a593SmuzhiyunBinding for Imagination Technologies MIPS Boston clock sources.
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThis binding uses the common clock binding[1].

6*4882a593Smuzhiyun
7*4882a593SmuzhiyunThe device node must be a child node of the syscon node corresponding to the
8*4882a593SmuzhiyunBoston system's platform registers.
9*4882a593Smuzhiyun
10*4882a593SmuzhiyunRequired properties:
11*4882a593Smuzhiyun- compatible : Should be "img,boston-clock".
12*4882a593Smuzhiyun- #clock-cells : Should be set to 1.
13*4882a593Smuzhiyun  Values available for clock consumers can be found in the header file:
14*4882a593Smuzhiyun    <dt-bindings/clock/boston-clock.h>
