2009-07-28USB: xhci: Scratchpad buffer allocationJohn Youn
Allocates and initializes the scratchpad buffer array (XHCI 4.20). This is an array of 64-bit DMA addresses to scratch pages that the controller may use during operation. The number of pages is specified in the "Max Scratchpad Buffers" field of HCSPARAMS2. The DMA address of this array is written into slot 0 of the DCBAA.

2009-07-28USB: Fix parsing of SuperSpeed Endpoint Companion descriptor.Sarah Sharp
usb_parse_ss_endpoint_companion() was supposed to allocate a structure to hold the SuperSpeed Endpoint Companion descriptor, and either copy the values the device returned, or fill in default values if the device descriptor did not include the companion descriptor. However, the previous code would miss the last endpoint in a configuration with no descriptors after it. Make usb_parse_endpoint() allocate the SS endpoint companion descriptor and fill it with default values, even if we've run out of buffer space in this configuration descriptor.

2009-07-28USB: xhci: Setup HW retries correctly.Sarah Sharp
The xHCI host controller can be programmed to retry a transfer a certain number of times per endpoint before it passes back an error condition to the host controller driver. The xHC will return an error code when the error count transitions from 1 to 0. Programming an error count of 3 means the xHC tries the transfer 3 times, programming it with a 1 means it tries to transfer once, and programming it with 0 means the HW tries the transfer infinitely. We want isochronous transfers to only be tried once, so set the error count to one. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-07-28USB: xhci: Correct Event Handler Busy flag usage.Sarah Sharp
The Event Handler Busy bit in the event ring dequeue pointer is write 1 to clear. Fix the interrupt service routine to clear that bit after the event handler has run. xhci_set_hc_event_deq() is designed to update the event ring dequeue pointer without changing any of the four reserved bits in the lower nibble. The event handler busy (EHB) bit is write one to clear, so the new value must always contain a zero in that bit in order to preserve the EHB value.

2009-07-28USB: xhci: Handle short control packets correctly.Sarah Sharp
When there is a short packet on a control transfer, the xHCI host controller hardware will generate two events. The first event will be for the data stage TD with a completion code for a short packet. The second event will be for the status stage with a successful completion code. Before this patch, the xHCI driver would giveback the short control URB when it received the event for the data stage TD. Then it would become confused when it saw a status stage event for the endpoint for an URB it had already finished processing. Change the xHCI host controller driver to wait for the status stage event when it receives a short transfer completion code for a data stage TD.

2009-07-28USB: xhci: Represent 64-bit addresses with one u64.Sarah Sharp
There are several xHCI data structures that use two 32-bit fields to represent a 64-bit address. Since some architectures don't support 64-bit PCI writes, the fields need to be written in two 32-bit writes. The xHCI specification says that if a platform is incapable of generating 64-bit writes, software must write the low 32-bits first, then the high 32-bits. Hardware that supports 64-bit addressing will wait for the high 32-bit write before reading the revised value, and hardware that only supports 32-bit writes will ignore the high 32-bit write. Previous xHCI code represented 64-bit addresses with two u32 values. This lead to buggy code that would write the 32-bits in the wrong order, or forget to write the upper 32-bits. Change the two u32s to one u64 and create a function call to write all 64-bit addresses in the proper order. This new function could be modified in the future if all platforms support 64-bit writes.

2009-07-28USB: xhci: Use GFP_ATOMIC while holding spinlocks.Sarah Sharp
The xHCI functions to queue an URB onto the hardware rings must be called with the xhci spinlock held. Those functions will allocate memory, and take a gfp_t memory flags argument. We must pass them the GFP_ATOMIC flag, since we don't want the memory allocation to attempt to sleep while waiting for more memory to become available.

2009-07-28USB: xhci: Deal with stalled endpoints.Sarah Sharp
When an endpoint on a device under an xHCI host controller stalls, the host controller driver must let the hardware know that the USB core has successfully cleared the halt condition. The HCD submits a Reset Endpoint Command, which will clear the toggle bit for USB 2.0 devices, and set the sequence number to zero for USB 3.0 devices. The xHCI urb_enqueue will accept new URBs while the endpoint is halted, and will queue them to the hardware rings. However, the endpoint doorbell will not be rung until the Reset Endpoint Command completes. Don't queue a reset endpoint command for root hubs. khubd clears halt conditions on the roothub during the initialization process, but the roothub isn't a real device, so the xHCI host controller doesn't need to know about the cleared halt.

2009-07-28USB: xhci: Set TD size in transfer TRB.Sarah Sharp
The 0.95 xHCI specification requires software to set the "TD size" field in each transaction request block (TRB). This field gives the host controller an indication of how much data is remaining in the TD (including the buffer in the current TRB).

Currently the default register access mode is set to FLAT_MODE thus INDEX register is not getting set properly with musb_ep_select() which is just a nop operation in FLAT_MODE.This invalid register read is causing module reinset failure.

2009-07-28USB: aten uc2324 is really a moschip 7840Russell Lang
I've opened up the case, and the chips in the ATEN UC2324 are: Moschip MCS7840CV-AA 69507-6B1 0650 (USB to 4-port serial) (logo with AF kerned together) 0748 24BC02 SINGLP (unknown 8-pin chip) (logo looks like 3 or Z in circle) ZT3243LEEA 0752 B7A16420.T (4 chips, so this will be RS232 line driver) (Probably equivalent of Sipex SP3243) So the ATEN 2324 (aten2011.c driver), is definitely the Moschip 7840, and should use the mos7840.c driver. I expect you will remove the aten2011.c driver from the staging area. From the aten2011.c source code, the device ID for the UC2322 (2 port serial) is 0x7820, just like the Moschip evaluation board. This value should be added to the device id table of mos7840.c. Here's a patch that adds these devices to the driver.

2009-07-28USB: storage: raise timeout in usb_stor_Bulk_max_lunGiacomo Lozito
Requests to get max LUN, for certain USB storage devices, require a longer timeout before a correct reply is returned. This happens for a Realtek USB Card Reader (0bda:0152), which has a max LUN of 3 but is set to 0, thus losing functionality, because of the timeout occurring too quickly. Raising the timeout value fixes the issue and might help other devices to return a correct max LUN value as well.
