USB EHCI controllers
Required properties:
- - compatible : should be "usb-ehci".
+ - compatible : should be "generic-ehci".
- reg : should contain at least address and length of the standard EHCI
register set for the device. Optional platform-dependent registers
(debug-port or other) can be also specified here, but only after
definition of standard EHCI registers.
- interrupts : one EHCI interrupt should be described here.
-If device registers are implemented in big endian mode, the device
-node should have "big-endian-regs" property.
-If controller implementation operates with big endian descriptors,
-"big-endian-desc" property should be specified.
-If both big endian registers and descriptors are used by the controller
-implementation, "big-endian" property can be specified instead of having
-both "big-endian-regs" and "big-endian-desc".
+
+Optional properties:
+ - big-endian-regs : boolean, set this for hcds with big-endian registers
+ - big-endian-desc : boolean, set this for hcds with big-endian descriptors
+ - big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
+ - clocks : a list of phandle + clock specifier pairs
+ - phys : phandle + phy specifier pair
+ - phy-names : "usb"
Example (Sequoia 440EPx):
ehci@e0000300 {
reg = <0 e0000300 90 0 e0000390 70>;
big-endian;
};
+
+Example (Allwinner sun4i A10 SoC):
+ ehci0: usb@01c14000 {
+ compatible = "allwinner,sun4i-a10-ehci", "generic-ehci";
+ reg = <0x01c14000 0x100>;
+ interrupts = <39>;
+ clocks = <&ahb_gates 1>;
+ phys = <&usbphy 1>;
+ phy-names = "usb";

+USB OHCI controllers
+
+Required properties:
+- compatible : "generic-ohci"
+- reg : ohci controller register range (address and length)
+- interrupts : ohci controller interrupt
+
+Optional properties:
+- big-endian-regs : boolean, set this for hcds with big-endian registers
+- big-endian-desc : boolean, set this for hcds with big-endian descriptors
+- big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
+- clocks : a list of phandle + clock specifier pairs
+- phys : phandle + phy specifier pair
+- phy-names : "usb"
+
+Example:
+
+ ohci0: usb@01c14400 {
+ compatible = "allwinner,sun4i-a10-ohci", "generic-ohci";
+ reg = <0x01c14400 0x100>;

Required properties:
-- compatible : "platform-uhci"
+- compatible : "generic-uhci" (deprecated: "platform-uhci")
- reg : Should contain 1 register ranges(address and length)
- interrupts : UHCI controller interrupt
Example:

- compatible = "platform-uhci";
+ compatible = "generic-uhci";
reg = <0xd8007b00 0x200>;
interrupts = <43>;

USB xHCI controllers
Required properties:
- - compatible: should be "xhci-platform".
+ - compatible: should be "generic-xhci" (deprecated: "xhci-platform").
- reg: should contain address and length of the standard XHCI
register set for the device.
- interrupts: one XHCI interrupt should be described here.
Example:
usb@f0931000 {
- compatible = "xhci-platform";
