1 Binding for a type of quad channel digital frequency synthesizer found on
2 certain STMicroelectronics consumer electronics SoC devices.
3
4 This version contains a programmable PLL which can generate up to 216, 432
5 or 660MHz (from a 30MHz oscillator input) as the input to the digital
6 synthesizers.
7
8 This binding uses the common clock binding[1].

12 Required 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
19 - #clock-cells : from common clock binding; shall be set to 1.
20
21 - reg : A Base address and length of the register set.
22
23 - clocks : from common clock binding
24
25 - clock-output-names : From common clock binding. The block has 4
26                        clock outputs but not all of them in a specific instance
27                        have to be used in the SoC. If a clock name is left as
28                        an empty string then no clock will be created for the
29                        output associated with that string index. If fewer than
30                        4 strings are provided then no clocks will be created
31                        for the remaining outputs.

33 Example:
34
35         CLOCKGEN_E: CLOCKGEN_E {
36                 #clock-cells = <1>;
37                 compatible = "st,stih416-quadfs660-E", "st,quadfs";
38                 reg = <0xfd3208bc 0xB0>;
39
40                 clocks = <&CLK_SYSIN>;
41                 clock-output-names = "CLK_M_PIX_MDTP_0",
42                                         "CLK_M_PIX_MDTP_1",
43                                         "CLK_M_PIX_MDTP_2",
44                                         "CLK_M_MPELPC";
