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.

[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
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;
|
|
};
