Improve the binding example by removing all the leading zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"` Some unnecessary changes were manually fixed.

Allwinner sun9i USB PHY
|
|
-----------------------
|
|
|
|
Required properties:
|
|
- compatible : should be one of
|
|
* allwinner,sun9i-a80-usb-phy
|
|
- reg : a list of offset + length pairs
|
|
- #phy-cells : from the generic phy bindings, must be 0
|
|
- phy_type : "hsic" for HSIC usage;
|
|
other values or absence of this property indicates normal USB
|
|
- clocks : phandle + clock specifier for the phy clocks
|
|
- clock-names : depending on the "phy_type" property,
|
|
* "phy" for normal USB
|
|
* "hsic_480M", "hsic_12M" for HSIC
|
|
- resets : a list of phandle + reset specifier pairs
|
|
- reset-names : depending on the "phy_type" property,
|
|
* "phy" for normal USB
|
|
* "hsic" for HSIC
|
|
|
|
Optional Properties:
|
|
- phy-supply : from the generic phy bindings, a phandle to a regulator that
|
|
provides power to VBUS.
|
|
|
|
It is recommended to list all clocks and resets available.
|
|
The driver will only use those matching the phy_type.
|
|
|
|
Example:
|
|
usbphy1: phy@a01800 {
|
|
compatible = "allwinner,sun9i-a80-usb-phy";
|
|
reg = <0x00a01800 0x4>;
|
|
clocks = <&usb_phy_clk 2>, <&usb_phy_clk 10>,
|
|
<&usb_phy_clk 3>;
|
|
clock-names = "hsic_480M", "hsic_12M", "phy";
|
|
resets = <&usb_phy_clk 18>, <&usb_phy_clk 19>;
|
|
reset-names = "hsic", "phy";
|
|
#phy-cells = <0>;
|
|
};
