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.

2011-12-09USB: cdc-acm: Fix potential deadlock (lockdep warning)Havard Skinnemoen
Rework the locking and lifecycle management in the cdc-acm driver. Instead of using a global mutex to prevent the 'acm' object from being freed, use the tty_port kref to keep the device alive when either the USB side or TTY side is still active. This allows us to use the global mutex purely for protecting the acm_table, while use acm->mutex to guard against disconnect during TTY port activation and shutdown. The USB-side kref is taken during port initialization in probe(), and released at the end of disconnect(). The TTY-side kref is taken in install() and released in cleanup(). On disconnect, tty_vhangup() is called instead of tty_hangup() to ensure the TTY hangup processing is completed before the USB device is taken down. The TTY open and close handlers have been gutted and replaced with tty_port_open() and tty_port_close() respectively. The driver-specific code which used to be there was spread across install(), activate() and shutdown().

PS3 EHCI HC errata fix 244. The SCC EHCI HC will not correctly perform QH reads that occur near or span a micro-frame boundry. This is due to a problem in the Nak Count Reload Control logic (EHCI Specification 1.0 Section 4.9.1). The work-around for this problem is for the HC driver to set I=1 (inactive) for QHs with H=1 (list head).

The EHCI USB controller of the Cell Super Companion Chip used in the PS3 will stop the root hub after all root hub ports are suspended. When in this condition the ehci-hcd handshake routine will return -ETIMEDOUT and the USB runtime suspend sequence will fail. The STS_HLT bit will not be set, so inspection of the frame index is used to test for the condition. Add a new routine handshake_for_broken_root_hub() that is called after an unsuccessful -ETIMEDOUT handshake. On PS3 handshake_for_broken_root_hub() will test for the condition, and if found will return success to allow the USB suspend to complete. For all other platforms handshake_for_broken_root_hub() will return -ETIMEDOUT Signed-off-by: Geoff Levand <geoff@infradead.org> Signed-off-by: Alan Stern <stern@rowland.harvard.edu>
