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]

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";
