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.

[2] Documentation/devicetree/bindings/clock/gate-clock.txt
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:
- ti,bit-shift : bit shift for the bit enabling/disabling the clock (default 0)
Examples:
aes1_ick: aes1_ick@48004a14 {
#clock-cells = <0>;
compatible = "ti,omap3-interface-clock";
clocks = <&security_l4_ick2>;
reg = <0x48004a14 0x4>;
ti,bit-shift = <3>;
};
cam_ick: cam_ick@48004f10 {
#clock-cells = <0>;
compatible = "ti,omap3-no-wait-interface-clock";
clocks = <&l4_ick>;
reg = <0x48004f10 0x4>;
ti,bit-shift = <0>;
};
ssi_ick_3430es2: ssi_ick_3430es2@48004a10 {
#clock-cells = <0>;
compatible = "ti,omap3-ssi-interface-clock";
clocks = <&ssi_l4_ick>;
reg = <0x48004a10 0x4>;
ti,bit-shift = <0>;
};
