This should allow using ohci-platform from devicetree in various cases. Specifically after this commit it can be used for the ohci controller found on Allwinner sunxi SoCs.

OHCI controller always uses MMIO, and likewise EHCI. You don't need to
specifically mention it.
+ +Required properties: +- compatible : "mmio-ohci"
Likewise, it's not a good name. Why not call it "platform-ohci"?
+- reg : ohci controller register range (address and length)
+- interrupts : ohci controller interrupt
+
+Optional properties:
+- clocks : a list of phandle + clock specifier pairs
+- phys : phandle + phy specifier pair
+- phy-names : "usb"
+
+Example:
+
+ ohci0: ohci at 0x01c14400 {
+ compatible = "mmio-ohci";
+ reg = <0x01c14400 0x100>;
+ interrupts = <64>;
+ clocks = <&usb_clk 6>, <&ahb_gates 2>;
+ phys = <&usbphy 1>;
+ phy-names = "usb";
