Socionext UniPhier Regulator Controller
|
||||
|
||||
This describes the devicetree bindings for regulator controller implemented
|
||||
on Socionext UniPhier SoCs.
|
||||
|
||||
USB3 Controller
|
||||
---------------
|
||||
|
||||
This regulator controls VBUS and belongs to USB3 glue layer. Before using
|
||||
the regulator, it is necessary to control the clocks and resets to enable
|
||||
this layer. These clocks and resets should be described in each property.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be
|
||||
"socionext,uniphier-pro4-usb3-regulator" - for Pro4 SoC
|
||||
"socionext,uniphier-pro5-usb3-regulator" - for Pro5 SoC
|
||||
"socionext,uniphier-pxs2-usb3-regulator" - for PXs2 SoC
|
||||
"socionext,uniphier-ld20-usb3-regulator" - for LD20 SoC
|
||||
"socionext,uniphier-pxs3-usb3-regulator" - for PXs3 SoC
|
||||
- reg: Specifies offset and length of the register set for the device.
|
||||
- clocks: A list of phandles to the clock gate for USB3 glue layer.
|
||||
According to the clock-names, appropriate clocks are required.
|
||||
- clock-names: Should contain
|
||||
"gio", "link" - for Pro4 and Pro5 SoCs
|
||||
"link" - for others
|
||||
- resets: A list of phandles to the reset control for USB3 glue layer.
|
||||
According to the reset-names, appropriate resets are required.
|
||||
- reset-names: Should contain
|
||||
"gio", "link" - for Pro4 and Pro5 SoCs
|
||||
"link" - for others
|
||||
|
||||
See Documentation/devicetree/bindings/regulator/regulator.txt
|
||||
for more details about the regulator properties.
|
||||
|
||||
Example:
|
||||
|
||||
usb-glue@65b00000 {
|
||||
compatible = "socionext,uniphier-ld20-dwc3-glue",
|
||||
"simple-mfd";
|
||||
#address-cells = <1>;
|
||||
#size-cells = <1>;
|
||||
ranges = <0 0x65b00000 0x400>;
|
||||
|
||||
usb_vbus0: regulators@100 {
|
||||
compatible = "socionext,uniphier-ld20-usb3-regulator";
|
||||
reg = <0x100 0x10>;
|
||||
clock-names = "link";
|
||||
clocks = <&sys_clk 14>;
|
||||
reset-names = "link";
|
||||
resets = <&sys_rst 14>;
|
||||
};
|
||||
|
||||
phy {
|
||||
...
|
||||
phy-supply = <&usb_vbus0>;
|
||||
};
|
||||
...
|
||||
};
