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

12 Required properties:
13 - compatible : shall be one of:
14 "ti,omap3-interface-clock" - basic OMAP3 interface clock
15 "ti,omap3-no-wait-interface-clock" - interface clock which has no hardware
16 capability for waiting clock to be ready
17 "ti,omap3-hsotgusb-interface-clock" - interface clock with USB specific HW
18 handling
19 "ti,omap3-dss-interface-clock" - interface clock with DSS specific HW handling
20 "ti,omap3-ssi-interface-clock" - interface clock with SSI specific HW handling
21 "ti,am35xx-interface-clock" - interface clock with AM35xx specific HW handling
22 "ti,omap2430-interface-clock" - interface clock with OMAP2430 specific HW
23 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
28 Optional properties:
29 - clock-output-names : from common clock binding.
30 - ti,bit-shift : bit shift for the bit enabling/disabling the clock (default 0)
