[PATCH] xhci: Add BayTrail to list of Intel switchable hosts

2013-05-20 Thread Heikki Krogerus
From: "Chew, Chiau Ee" Like the xHCI controller on Intel Panther Point and Lynx Point chipsets, the xHCI controller on Intel BayTrail has also ports that can be switched between the EHCI host controller. This patch should be backported to stable kernels as old as 3.0, that contain commit 69e848c

At this point the port switchover quirk is getting unwieldy. I know of at least two more platforms that will need the switchover quirk, and it's silly to keep adding them to the list. Heikki, can you change the code to always try to switchover the ports from EHCI to xHCI if an Intel xHCI host is
