1 Binding for Texas Instruments gate clock.
3 This binding uses the common clock binding[1]. This clock is
4 quite much similar to the basic gate-clock [2], however,
6 is provided for this clock, the code assumes that a clockdomain
7 will be controlled instead and the corresponding hw-ops for

15 - compatible : shall be one of:
16   "ti,gate-clock" - basic gate clock
17   "ti,wait-gate-clock" - gate clock which waits until clock is active before
19   "ti,dss-gate-clock" - gate clock with DSS specific hardware handling
20   "ti,am35xx-gate-clock" - gate clock with AM35xx specific hardware handling
21   "ti,clkdm-gate-clock" - clockdomain gate clock, which derives its functional
22 			  clock directly from a clockdomain, see [3] how
24   "ti,hsdiv-gate-clock" - gate clock with OMAP36xx specific hardware handling,
26   "ti,composite-gate-clock" - composite gate clock, to be part of composite
27 			      clock
28   "ti,composite-no-wait-gate-clock" - composite gate clock that does not wait
29 				      for clock to be active before returning
31 - #clock-cells : from common clock binding; shall be set to 0
32 - clocks : link to phandle of parent clock
33 - reg : offset for register controlling adjustable gate, not needed for
34 	ti,clkdm-gate-clock type
37 - clock-output-names : from common clock binding.
38 - ti,bit-shift : bit shift for programming the clock gate, invalid for
39 		 ti,clkdm-gate-clock type
40 - ti,set-bit-to-disable : inverts default gate programming. Setting the bit
41   gates the clock and clearing the bit ungates the clock.
