Hi,
This is the 6th version of the patchset aiming to rework ci13xxx
driver. With this patchset, the driver also supports an older version
of chipidea found in Marvell's Feroceon SoC, that is, it works with
sheevaplug (provided you can find or make a USB A-to-A cable).
This patchset fixes several bugs in the udc driver and addresses
some of the style issues. This patchset also includes conversion to
platform_device, which in case if msm is only compile-tested. While
at it, I have also converted "choice" of UDC controllers into a menu,
since we can probably have more than one UDC in the system, at least
theoretically.
It also converts ci13xxx_udc to the "new style", so that we can finally
get rid of the global _udc pointer and theoretically can now have as
many chipidea gadgets in the system as we please.
Then, it proceeds to move the driver to drivers/usb/chipidea and turn
it into a dual-role controller driver, complete with role switching
(manual and ID-pin based) and both device and host roles. Tested on
both sheevaplug and penwell. The former requires modifications to the
platform code in arch/arm, which are not part of these series. The
latter just works.
Finally, it removes langwell_udc driver, as it is now covered by the
reworked chipidea driver too and adds a new entry in MAINTAINERS.
New since the previous version:
* moved platform data of the pci driver to driver_data in pci_id
tables as Felipe suggested,
* split "new style" conversion into two patches, first of which moves
endpoint initialization from start() to probe(), per Felipe's request,
* fixed deferred address setting per Felipe's comment,
* minor fixes here and there per Felipe's comments,
* removed langwell_udc,
* added a MAINTAINERS entry
