2012-08-10drivers/usb/host/ehci-vt8500.c: use devm_ functionsJulia Lawall
The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function.

2012-07-09EHCI: centralize controller initializationAlan Stern
This patch (as1564c) converts the EHCI platform drivers to use the central ehci_setup() routine for generic controller initialization rather than each having its own idiosyncratic approach. The major point of difficulty lies in ehci-pci's many vendor- and device-specific workarounds. Some of them have to be applied before calling ehci_setup() and some after, which necessitates a fair amount of code motion. The other platform drivers require much smaller changes. One point not addressed by the patch is whether ports should be powered on or off following initialization. The different drivers appear to handle this pretty much at random. In fact it shouldn't matter, because the hub driver turns on power to all ports when it binds to the root hub. Straightening that out will be left for another day.

2011-12-08usb: Remove ehci_reset call from ehci_runGeoff Levand
Remove the ehci_reset() call done in the ehci_run() routine of the USB EHCI host controller driver and add an ehci_reset() call to the probe processing of all EHCI platform drivers that do not already call ehci_reset(). The call to ehci_reset() from ehci_run() was problematic for several platform drivers, and unnecessary for others. This change moves the decision to call ehci_reset() at driver startup to the platform driver code. Signed-off-by: Geoff Levand <geoff@infradead.org> Acked-by: Alan Stern <stern@rowland.harvard.edu>

2011-05-03USB: EHCI: Support controllers with big endian capability regsJan Andersson
The two first HC capability registers (CAPLENGTH and HCIVERSION) are defined as one 8-bit and one 16-bit register. Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.

2010-11-11usb: Add support for VIA VT8500 and compatibles in EHCI HCDAlexey Charkov
VIA and WonderMedia Systems-on-Chip feature a standard EHCI host controller. This adds necessary glue to use the standard driver with these systems. Signed-off-by: Alexey Charkov <alchark@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
