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].

12Required properties:
13- compatible : shall be:
14 "st,stih416-quadfs216", "st,quadfs"
15 "st,stih416-quadfs432", "st,quadfs"
16 "st,stih416-quadfs660-E", "st,quadfs"
17 "st,stih416-quadfs660-F", "st,quadfs"
18 "st,stih407-quadfs660-C", "st,quadfs"
19 "st,stih407-quadfs660-D", "st,quadfs"

21
22- #clock-cells : from common clock binding; shall be set to 1.
23
24- reg : A Base address and length of the register set.
25
26- clocks : from common clock binding
27
28- clock-output-names : From common clock binding. The block has 4
29 clock outputs but not all of them in a specific instance
30 have to be used in the SoC. If a clock name is left as
31 an empty string then no clock will be created for the
32 output associated with that string index. If fewer than
33 4 strings are provided then no clocks will be created
34 for the remaining outputs.

36Example:
37
38 clockgen_e: clockgen-e@fd3208bc {
39 #clock-cells = <1>;
40 compatible = "st,stih416-quadfs660-E", "st,quadfs";
41 reg = <0xfd3208bc 0xB0>;
42
43 clocks = <&clk_sysin>;
44 clock-output-names = "clk-m-pix-mdtp-0",
45 "clk-m-pix-mdtp-1",
46 "clk-m-pix-mdtp-2",
47 "clk-m-mpelpc";
48 };
