Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 3 | This binding uses the common clock binding[1], and also uses the autoidle |
| 4 | support from TI autoidle clock [2]. |

| 9 | Required properties: |
| 10 | - compatible : shall be "ti,fixed-factor-clock". |
| 11 | - #clock-cells : from common clock binding; shall be set to 0. |
| 12 | - ti,clock-div: fixed divider. |
| 13 | - ti,clock-mult: fixed multiplier. |
| 14 | - clocks: parent clock. |
| 15 | |
| 16 | Optional properties: |
| 17 | - clock-output-names : from common clock binding. |
| 18 | - ti,autoidle-shift: bit shift of the autoidle enable bit for the clock, |
| 19 | see [2] |
| 20 | - reg: offset for the autoidle register of this clock, see [2] |
| 21 | - ti,invert-autoidle-bit: autoidle is enabled by setting the bit to 0, see [2] |
| 22 | - ti,set-rate-parent: clk_set_rate is propagated to parent |
| 23 | |
| 24 | Example: |
| 25 | clock { |
| 26 | compatible = "ti,fixed-factor-clock"; |
| 27 | clocks = <&parentclk>; |
| 28 | #clock-cells = <0>; |
| 29 | ti,clock-div = <2>; |
| 30 | ti,clock-mult = <1>; |
| 31 | }; |
| 32 | |
| 33 | dpll_usb_clkdcoldo_ck: dpll_usb_clkdcoldo_ck { |
| 34 | #clock-cells = <0>; |
| 35 | compatible = "ti,fixed-factor-clock"; |
| 36 | clocks = <&dpll_usb_ck>; |
| 37 | ti,clock-div = <1>; |
| 38 | ti,autoidle-shift = <8>; |
| 39 | reg = <0x01b4>; |
| 40 | ti,clock-mult = <1>; |
| 41 | ti,invert-autoidle-bit; |
| 42 | }; |
