| Binding for a type of quad channel digital frequency synthesizer found on | |
| certain STMicroelectronics consumer electronics SoC devices. | |
| This version contains a programmable PLL which can generate up to 216, 432 | |
| or 660MHz (from a 30MHz oscillator input) as the input to the digital | |
| synthesizers. | |
| This binding uses the common clock binding[1]. | |
| [1] Documentation/devicetree/bindings/clock/clock-bindings.txt | |
| Required properties: | |
| - compatible : shall be: | |
| "st,quadfs" | |
| "st,quadfs-pll" | |
| - #clock-cells : from common clock binding; shall be set to 1. | |
| - reg : A Base address and length of the register set. | |
| - clocks : from common clock binding | |
| - clock-output-names : From common clock binding. The block has 4 | |
| clock outputs but not all of them in a specific instance | |
| have to be used in the SoC. If a clock name is left as | |
| an empty string then no clock will be created for the | |
| output associated with that string index. If fewer than | |
| 4 strings are provided then no clocks will be created | |
| for the remaining outputs. | |
| Example: | |
| clk_s_c0_quadfs: clk-s-c0-quadfs@9103000 { | |
| #clock-cells = <1>; | |
| compatible = "st,quadfs-pll"; | |
| reg = <0x9103000 0x1000>; | |
| clocks = <&clk_sysin>; | |
| clock-output-names = "clk-s-c0-fs0-ch0", | |
| "clk-s-c0-fs0-ch1", | |
| "clk-s-c0-fs0-ch2", | |
| "clk-s-c0-fs0-ch3"; | |
| }; |
