2011-12-12usb: dwc3: host: remove unused includesSebastian Andrzej Siewior
None of these are required atm. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-12usb: dwc3: debugfs: hold the lock in during mode changeSebastian Andrzej Siewior
The read and write operation is atomic and we need no locking around this operations. What we need however is a lock that is held which ensures that the content of the DWC3_GCTL has not been changed. With this, the conten may have been change changed after the first but before our write back.

2011-12-12usb: dwc3: add a platform device aliasSebastian Andrzej Siewior
We can have three modules here: dwc3.ko, dwc3-omap.ko and dwc3-pci.ko. The later have already ids-aliases for probing and is fine. The omap module has alias for DT but lacks alias for the "native" platform_device. Maybe we should get rid of it and stick to the DT name? Both glue modules create a new device for which the dwc3.ko module is responsible and that one lacks the platform alias.

2011-12-12usb: dwc3: ep0: handle unexpected XferNotReady eventsFelipe Balbi
Sometimes the host might be trying to initiate Data or Status phase for an older Control transfer. In such situations we must STALL that transfer and restart the state machine rather than letting such situation go through the wire. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-12usb: dwc3: debugfs: add support for changing port modeFelipe Balbi
This makes testing a lot easier when trying to switch between host and device modes. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-12usb: dwc3: ep0: SetAddress() won't be issued while ConfiguredFelipe Balbi
I have talked to USB-IF about USB30CV issuing SetAddres() with a device on Configured state and they have agreed on changing USB30CV not to do so. Adding back the STALL reply in such case and while at that, also add a debugging message for an address which is too large. Signed-off-by: Felipe Balbi <balbi@ti.com>

2011-12-12usb: dwc3: add xHCI Host supportFelipe Balbi
The Designware USB3 IP can be configured with an internal xHCI. If we're running on such a version, let's start the xHCI stack. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-12usb: dwc3: fetch mode of operation from HWFelipe Balbi
There's no need to add driver_data for something we can fetch from HW. This also makes our id_table unnecessary - at least for now -, so we also remove it on the same patch. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-12usb: dwc3: calculate number of event buffers dynamicallyFelipe Balbi
This will allow us to only allocate memory when we actually need. Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-12-12usb: dwc3: allow forcing a maximum speedFelipe Balbi
this is mainly for testing. In order to be able to test if we're enumerating correctly on all speeds, let that be controlled by a module parameter. Signed-off-by: Felipe Balbi <balbi@ti.com>

2011-12-12usb: gadget: mv_udc: refine suspend/resume functionNeil Zhang
This patch impletments system suspend/resume functions for Marvell otg controller. If OTG is enabled, OTG driver will do most of the work. If not, we will check clock gating. If clock gating is enabled, the UDC will be start/stop automatically. If not, UDC will be start/stop in suspend/resume functions.

2011-12-12usb: gadget: Use kcalloc instead of kzalloc to allocate arrayThomas Meyer
The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read.

2011-12-12usb: gadget: rename usb_gadget_driver::speed to max_speedMichal Nazarewicz
This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

2011-12-12usb: gadget: mass_storage: support multi-luns with different logic block sizeYuping Luo
With Peiyu's patch "gadget: mass_storage: adapt logic block size to bound block devices" (http://www.spinics.net/lists/linux-usb/msg50791.html), now mass storage can adjust logic block size dynamically based on real devices. Then there is one issue caused by it, if two luns have different logic block size, mass storage can't work. Let's check the current software flow: 1. get_next_command(): call received_cbw(); 2. received_cbw(): update common->lun = cbw->Lun, but common->curlen is not updated; 3. do_scsi_command(): in READ_X and WRITE_X commands, common->data_size_from_cmnd is updated by common->curlun->blkbits; 4. check_command(): update common->curlun according to common->lun As you can see, the step 3 uses wrong common->curlun, then wrong common->curlun->blkbits. If the two luns have same blkbits, there isn't issue. Otherwise, both will fail. This patch moves the common->curlun update to step 1, then make sure step 3 gets right blkbits and data_size_from_cmnd.
