Binding for a Clockgen hardware block found on
certain STMicroelectronics consumer electronics SoC devices.
A Clockgen node can contain pll, diviser or multiplexer nodes.
We will find only the base address of the Clockgen, this base
address is common of all subnode.
clockgen_node {
reg = <>;
pll_node {
...
};
quadfs_node {
...
};
mux_node {
...
};
flexgen_node {
...
};
...
};
This binding uses the common clock binding[1].
Each subnode should use the binding described in [2]..[7]
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
[3] Documentation/devicetree/bindings/clock/st/st,clkgen-mux.txt
[4] Documentation/devicetree/bindings/clock/st/st,clkgen-pll.txt
[7] Documentation/devicetree/bindings/clock/st/st,quadfs.txt
[8] Documentation/devicetree/bindings/clock/st/st,flexgen.txt
Required properties:
- reg : A Base address and length of the register set.
Example:
clockgen-a@90ff000 {
compatible = "st,clkgen-c32";
reg = <0x90ff000 0x1000>;
clk_s_a0_pll: clk-s-a0-pll {
#clock-cells = <1>;
compatible = "st,clkgen-pll0";
clocks = <&clk_sysin>;
clock-output-names = "clk-s-a0-pll-ofd-0";
};
clk_s_a0_flexgen: clk-s-a0-flexgen {
compatible = "st,flexgen";
#clock-cells = <1>;
clocks = <&clk_s_a0_pll 0>,
<&clk_sysin>;
clock-output-names = "clk-ic-lmi0";
};
};
