Binding for Texas Instruments autoidle clock.
This binding uses the common clock binding[1]. It assumes a register mapped
clock which can be put to idle automatically by hardware based on the usage
and a configuration bit setting. Autoidle clock is never an individual
clock, it is always a derivative of some basic clock like a gate, divider,
or fixed-factor.

Required properties:
- reg : offset for the register controlling the autoidle
- ti,autoidle-shift : bit shift of the autoidle enable bit
- ti,invert-autoidle-bit : autoidle is enabled by setting the bit to 0
Examples:
dpll_core_m4_ck: dpll_core_m4_ck {
#clock-cells = <0>;
compatible = "ti,divider-clock";
clocks = <&dpll_core_x2_ck>;
ti,max-div = <31>;
ti,autoidle-shift = <8>;
reg = <0x2d38>;
ti,index-starts-at-one;
ti,invert-autoidle-bit;
};
dpll_usb_clkdcoldo_ck: dpll_usb_clkdcoldo_ck {
#clock-cells = <0>;
compatible = "ti,fixed-factor-clock";
clocks = <&dpll_usb_ck>;
ti,clock-div = <1>;
ti,autoidle-shift = <8>;
reg = <0x01b4>;
ti,clock-mult = <1>;
ti,invert-autoidle-bit;
};
