There are also lots of new drivers, pimarily gadget, but others as well. We deleted a staging driver, which was nice, and finally dropped the obsolete usbfs code, which will make Al happy to never have to touch that again.

2012-05-12usb/net: rndis: merge media type definitionsLinus Walleij
Let's have a unified table of RNDIS media. We used to have a similar table with NDIS_* prefix from the gadget driver, but since we're only using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows- internal network drivers so what do we care) let's prefix everything with RNDIS. Some of the definitions were conflicting, in one of the defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took the majority vote. Two definition of medium 0x09 calls it "wireless WAN" but one vote for "wireless LAN" but in this case I am sticking with the minority, "Wide Area Network" does not make much sense in this case as far as I can tell. NOTE: latin singular and plural is so screwed up in these defines that it makes my eyes bleed. But I will not attempt to submit a patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED is most probably (erroneously) referring to a singular, unless it can return an array of connected media. I suspect these erroneous plurals are used in documentation and such so I don't want to mess around with things for no functional change.

2012-05-11usb: gadget: ci13xxx: don't use "advance" feature when setting addressAlexander Shishkin
Newer versions of the chipidea controller support the "advance" setting of usb address, which means instead of setting it immediately, deferring it till the status completion. Unfortunately, older versions of the controller don't have this feature, so in order to support those too, we simply don't use it. It's about 4 lines of extra code, and isn't in any way critical to performance. While at it, change the return value of the hw_usb_set_address() to void, since it can't fail in any measurable way. With this patch, ci13xxx_udc driver works with the chipidea controller in kirkwood (feroceon SoC), as found in, for example, sheevaplug.

2012-05-09usb-gadget: Initial merge of target module for UASP + BOTSebastian Andrzej Siewior
This fabric uses the target framework to provide a usb gadget device. This gadget supports the USB Attached SCSI Protocol (UASP) and Bulk Only Transfers (BOT or BBB). BOT is the primary interface, UAS is the alternative interface. It has been tested with dummy_hcd on HS and SS. On SS USB3 are supported. I also took my omap device and tried it there against WindowsXP. UAS implements basic command passing (i.e. read/write requests) and TASK MANAGEMENT functions are missing. I had to add a little of error recovery to BOT because Windows was issuing some strange commands and it does not complain after the gadget responded with CSW.status=1.

This reference will have to go in order to allow us to have more than one chipidea udc in the system. Thus, replace custom macros with dev_{err,warn,info} using the platform device where possible.

2012-05-08usb: gadget: ci13xxx: rename register layoutsAlexander Shishkin
Currently, the register prefixes in the driver seem to be mixed: the capability registers are the ones that contain capability information, such as number of hardware endpoints, while the registers that are used to program the controller are called operational registers. Normally, capability registers start at 0x100 offset of the register window and are followed by operational registers. In some versions, however, capability registers start at 0x0 offset. This patch renames the register and adjusts their offsets appropriately, leaving the possibility of having a non-standard capability offset. I couldn't find any mentions of the TESTMODE register anywhere, so I suspect it might only be enabled in chipidea internal versions of the controller and I'm really inclined to remove it from the driver or at least hiding it behind a config option.

2012-05-07Merge tag 'gadget-for-v3.5' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: gadget: patches for v3.5 This pull request is quite big, but mainly because there's a giant rework of the s3c_hsotg.c driver to make it friendlier for other users. Samsung Exynos platforms use the DesignWare Core USB2 IP from Synopsys so it's a bit unfair to have the driver work for Samsung platforms only. In short, the big rework is in preparation to make the driver more reusable. Another big rework in this pull request came from Ido, where he's removing the redundant pointer for the endpoint descriptor from the controller driver's own endpoint representation. The same pointer is available through the generic struct usb_ep structure. Also on this pull request is the conversion of a few extra controller drivers to the new style registration, which allows multiple controllers to be available on the same platform and helps remove global pointers from those drivers. Together with those big changes, there's the usual fixes and cleanups to gadget drivers. Nothing major.

I previously cleaned up the err() call usage in this driver, but it really was calling this macro instead. To remove future confusion, just delete this unused macro now. Ideally, the warn() and info() macros should also be removed, and the "real" dev_warn() and dev_info() calls should be used instead.
