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";
};
