Subject: [PATCH] xhci-platform: Change compatible string from xhci-platform to
generic-xhci
This brings the xhci-platform bindings in sync with what we've done for
the ohci- and ehci-platform drivers. As discussed there using platform as a
postfix is a bit weird as the platform bus is a Linux specific thing and
the bindings are supposed to be OS agnostic.
Note that the old xhci-platform compatible string is kept around for, well,
compatibility reasons.

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";
+ compatible = "generic-xhci";
reg = <0xf0931000 0x8c8>;
interrupts = <0x0 0x4e 0x0>;
};
