2011-12-13usb: renesas_usbhs: care pipe sequenceKuninori Morimoto
driver has to re-use the limited pipe for each device/endpoint when it is USB host hub mode, since number of pipe has limitation. Then, each pipe should care own pipe sequence for next packet.

2011-12-13usb: renesas_usbhs: modify device attach methodKuninori Morimoto
Current renesas_usbhs had been assigning udev to each urb. It was executed even though it was device0. For this reason, the device0 had to set the new device address which has still not been assigned. (it will be assigned on next step). Current renesas_usbhs used fixed address for it. but it is not good for USB hub support. This patch modifies this issue.

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.
