| 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; |
| }; |
