Binding for TI fixed factor rate clock sources.
This binding uses the common clock binding[1], and also uses the autoidle
support from TI autoidle clock [2].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
[2] Documentation/devicetree/bindings/clock/ti/autoidle.txt
Required properties:
- compatible : shall be "ti,fixed-factor-clock".
- #clock-cells : from common clock binding; shall be set to 0.
- ti,clock-div: fixed divider.
- ti,clock-mult: fixed multiplier.
- clocks: parent clock.
Optional properties:
- clock-output-names : from common clock binding.
- ti,autoidle-shift: bit shift of the autoidle enable bit for the clock,
see [2]
- reg: offset for the autoidle register of this clock, see [2]
- ti,invert-autoidle-bit: autoidle is enabled by setting the bit to 0, see [2]
- ti,set-rate-parent: clk_set_rate is propagated to parent
Example:
clock {
compatible = "ti,fixed-factor-clock";
clocks = <&parentclk>;
#clock-cells = <0>;
ti,clock-div = <2>;
ti,clock-mult = <1>;
};
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;
};
