1*4882a593SmuzhiyunBinding for Texas Instruments FAPLL clock.
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]. It assumes a
6*4882a593Smuzhiyunregister-mapped FAPLL with usually two selectable input clocks
7*4882a593Smuzhiyun(reference clock and bypass clock), and one or more child
8*4882a593Smuzhiyunsyntesizers.

11*4882a593Smuzhiyun
12*4882a593SmuzhiyunRequired properties:
13*4882a593Smuzhiyun- compatible : shall be "ti,dm816-fapll-clock"
14*4882a593Smuzhiyun- #clock-cells : from common clock binding; shall be set to 0.
15*4882a593Smuzhiyun- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
16*4882a593Smuzhiyun- reg : address and length of the register set for controlling the FAPLL.
