1Binding for a type of quad channel digital frequency synthesizer found on 2certain STMicroelectronics consumer electronics SoC devices. 3 4This version contains a programmable PLL which can generate up to 216, 432 5or 660MHz (from a 30MHz oscillator input) as the input to the digital 6synthesizers. 7 8This binding uses the common clock binding[1]. 9 10[1] Documentation/devicetree/bindings/clock/clock-bindings.txt 11 12Required properties: 13- compatible : shall be: 14 "st,quadfs" 15 "st,quadfs-pll" 16 17 18- #clock-cells : from common clock binding; shall be set to 1. 19 20- reg : A Base address and length of the register set. 21 22- clocks : from common clock binding 23 24- clock-output-names : From common clock binding. The block has 4 25 clock outputs but not all of them in a specific instance 26 have to be used in the SoC. If a clock name is left as 27 an empty string then no clock will be created for the 28 output associated with that string index. If fewer than 29 4 strings are provided then no clocks will be created 30 for the remaining outputs. 31 32Example: 33 34 clk_s_c0_quadfs: clk-s-c0-quadfs@9103000 { 35 #clock-cells = <1>; 36 compatible = "st,quadfs-pll"; 37 reg = <0x9103000 0x1000>; 38 39 clocks = <&clk_sysin>; 40 41 clock-output-names = "clk-s-c0-fs0-ch0", 42 "clk-s-c0-fs0-ch1", 43 "clk-s-c0-fs0-ch2", 44 "clk-s-c0-fs0-ch3"; 45 }; 46
