     Binding for Texas Instruments autoidle clock.
     
     Binding status: Unstable - ABI compatibility may be broken in the future
     
     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;
            };
