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].

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";
|
||
|
|
};
