+Subject: [PATCH V2] usb: xhci: make USB_XHCI_PLATFORM selectable
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Right now xhci-plat-hcd can be built when using one of platform specific
+drivers only (mvebu/rcar). There shouldn't be such limitation as some
+platforms may not require any quirks and may want to just use a generic
+driver ("generic-xhci" / "xhci-hcd").

+Greg/Mathias: I'm not sure if it's more like USB subsystem stuff or xHCI
+Could you decide which one of you could pick that, please?
+
+V2: Drop useless "default n", thanks Sergei :)
