2012-10-31USB: EHCI: remove unused Link Power Management codeAlan Stern
This patch (as1622) removes the USB-2.1 Link Power Management code from the ehci-hcd driver. This code was never integrated with usbcore, it is full of bugs, and it was not getting used by anybody. However, the debugging code for dumping the LPM-related fields in the EHCI registers is left in place. In theory it might be useful to see these values, even though we don't use them. This essentially amounts to a partial revert of commit aa4d8342988d0c1a79ff19b2ede1e81dfbb16ea5 (USB: EHCI: EHCI 1.1 addendum: preparation) and an almost full revert of commit 48f24970144479c29b8cee6d2e1dbedf6dcf9cfb (USB: EHCI: EHCI 1.1 addendum: Basic LPM feature support) plus its follow-ons.

2012-10-31USB: remove iteration limit in hub_tt_work()Alan Stern
This patch (as1621) removes the limit on the number of loops allowed in hub_tt_work(). The value is arbitrary, and it's silly to have a limit in the first place -- anything beyond the limit would not get handled. Besides, it's most unlikely that we'll ever need to clear more than a couple of TT buffers at any time.

2012-10-31usb: musb: Perform only write access on MUSB_INTRTXESebastian Andrzej Siewior
This is part of the workaround for AM35x advisory Advisory 1.1.20. The advisory says that the IPSS bridge can't handle 8 & 16 bit read access. An 16bit read access to MUSB_INTRTXE results in an 32bit read access which also reads INTRRX and therefore may lose interrupts. This patch uses a shadow register of MUSB_INTRTXE so we only perform write access to it. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>

2012-10-31usb: gadget: dummy_hcd: remove global the_controller variableSebastian Andrzej Siewior
The one thing that makes two UDCs+HCDs impossible is the global the_controller variable. This patch changes this. After device allocation we allocate the "the_controller" variable and pass it as platform_data to the UDC and its companion. We can have now multiple instances dummy hcd and therefore I change the limit from one to two.

Instead of calling usb_string_id() multiple times I replace it with one usb_string_ids_tab(). The NULL pointer in struct usb_string with "" and are not overwritten in fail or unbind case. The conditional assignment remains because some gadgets recycle the string ID because the same descriptor (and string ID) is used if we have more than one config descriptor.

2012-10-31usb: gadget: always update HS/SS descriptors and create a copy of themSebastian Andrzej Siewior
HS and SS descriptors are staticaly created. They are updated during the bind process with the endpoint address, string id or interface numbers. After that, the descriptor chain is linked to struct usb_function which is used by composite in order to serve the GET_DESCRIPTOR requests, number of available configs and so on. There is no need to assign the HS descriptor only if the UDC supports HS speed because composite won't report those to the host if HS support has not been reached. The same reasoning is valid for SS. This patch makes sure each function updates HS/SS descriptors unconditionally and uses the newly introduced helper function to create a copy the descriptors for the speed which is supported by the UDC. While at that, also rename f->descriptors to f->fs_descriptors in order to make it more explicit what that means.

2012-10-31usb: gadget: uvc: fix error path in uvc_function_bind()Sebastian Andrzej Siewior
The "video->minor = -1" assigment is done in V4L2 by video_register_device() so it is removed here. Now. uvc_function_bind() calls in error case uvc_function_unbind() for cleanup. The problem is that uvc_function_unbind() frees the uvc struct and uvc_bind_config() does as well in error case of usb_add_function(). Removing kfree() in usb_add_function() would make the patch smaller but it would look odd because the new allocated memory is not cleaned up. However it is not guaranteed that if we call usb_add_function() we also get to the bind function. Therefore the patch extracts the conditional cleanup from uvc_function_unbind() applies to uvc_function_bind(). uvc_function_unbind() now contains only the complete cleanup which is required once everything has been registrated.

commit 65b3d52d02a558fbfe08e43688e15390c5ab3067 (usb: musb: add musb_ida for multi instance support) used musbid in ux500_remove() but nerver declared it. I found this in x86_64 platform, but not sure whether this is a error on the correct ARCH. $ make drivers/usb/musb/ux500.o make[1]: Nothing to be done for `all'. make[1]: Nothing to be done for `relocs'.
