Broadcom Cygnus device tree bindings
|
||||||
|
------------------------------------
|
||||||
|
|
||||||
|
|
||||||
|
Boards with Cygnus SoCs shall have the following properties:
|
||||||
|
|
||||||
|
Required root node property:
|
||||||
|
|
||||||
|
BCM11300
|
||||||
|
compatible = "brcm,bcm11300", "brcm,cygnus";
|
||||||
|
|
||||||
|
BCM11320
|
||||||
|
compatible = "brcm,bcm11320", "brcm,cygnus";
|
||||||
|
|
||||||
|
BCM11350
|
||||||
|
compatible = "brcm,bcm11350", "brcm,cygnus";
|

Broadcom Cygnus Clocks
|
||||||
|
|
||||||
|
This binding uses the common clock binding:
|
||||||
|
Documentation/devicetree/bindings/clock/clock-bindings.txt
|
||||||
|
|
||||||
|
Currently various "fixed" clocks are declared for peripheral drivers that use
|
||||||
|
the common clock framework to reference their core clocks. Proper support of
|
||||||
|
these clocks will be added later
|
||||||
|
|
||||||
|
Device tree example:
|
||||||
|
|
||||||
|
clocks {
|
||||||
|
#address-cells = <1>;
|
||||||
|
#size-cells = <1>;
|
||||||
|
ranges;
|
||||||
|
|
||||||
|
osc: oscillator {
|
||||||
|
compatible = "fixed-clock";
|
||||||
|
#clock-cells = <1>;
|
||||||
|
clock-frequency = <25000000>;
|
||||||
|
};
|
||||||
|
|
||||||
|
apb_clk: apb_clk {
|
||||||
|
compatible = "fixed-clock";
|
||||||
|
#clock-cells = <0>;
|
||||||
|
clock-frequency = <1000000000>;
|
||||||
|
};
|
||||||
|
|
||||||
|
periph_clk: periph_clk {
|
||||||
|
compatible = "fixed-clock";
|
||||||
|
#clock-cells = <0>;
|
||||||
|
clock-frequency = <500000000>;
|
||||||
|
};
|
||||||
|
};
