Several TI SoC clock bindings were marked as work-in-progress / unstable
between 2013-2016, for example in commit f60b1ea5ea ("CLK: TI: add
support for gate clock"). It was enough of time to consider them stable
and expect usual ABI rules.

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;
|
|
};
