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

Required properties:
|
||
|
|
- compatible : shall be one of:
|
||
|
|
"ti,omap3-interface-clock" - basic OMAP3 interface clock
|
||
|
|
"ti,omap3-no-wait-interface-clock" - interface clock which has no hardware
|
||
|
|
capability for waiting clock to be ready
|
||
|
|
"ti,omap3-hsotgusb-interface-clock" - interface clock with USB specific HW
|
||
|
|
handling
|
||
|
|
"ti,omap3-dss-interface-clock" - interface clock with DSS specific HW handling
|
||
|
|
"ti,omap3-ssi-interface-clock" - interface clock with SSI specific HW handling
|
||
|
|
"ti,am35xx-interface-clock" - interface clock with AM35xx specific HW handling
|
||
|
|
"ti,omap2430-interface-clock" - interface clock with OMAP2430 specific HW
|
||
|
|
handling
|
||
|
|
- #clock-cells : from common clock binding; shall be set to 0
|
||
|
|
- clocks : link to phandle of parent clock
|
||
|
|
- reg : base address for the control register
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- clock-output-names : from common clock binding.
|
||
|
|
- ti,bit-shift : bit shift for the bit enabling/disabling the clock (default 0)
