1Binding for Texas Instruments interface clock.
2
3Binding status: Unstable - ABI compatibility may be broken in the future
4
5This binding uses the common clock binding[1]. This clock is
6quite much similar to the basic gate-clock [2], however,
7it supports a number of additional features, including
8companion clock finding (match corresponding functional gate
9clock) and hardware autoidle enable / disable.

14Required properties:
15- compatible : shall be one of:
16 "ti,omap3-interface-clock" - basic OMAP3 interface clock
17 "ti,omap3-no-wait-interface-clock" - interface clock which has no hardware
18 capability for waiting clock to be ready
19 "ti,omap3-hsotgusb-interface-clock" - interface clock with USB specific HW
20 handling
21 "ti,omap3-dss-interface-clock" - interface clock with DSS specific HW handling
22 "ti,omap3-ssi-interface-clock" - interface clock with SSI specific HW handling
23 "ti,am35xx-interface-clock" - interface clock with AM35xx specific HW handling
24- #clock-cells : from common clock binding; shall be set to 0
25- clocks : link to phandle of parent clock
26- reg : base address for the control register
27
28Optional properties:
29- ti,bit-shift : bit shift for the bit enabling/disabling the clock (default 0)
