2011-02-20USB: xhci: fix couple sparse annotationsDmitry Torokhov
There is no point in casting to (void *) when setting up xhci->ir_set as it only makes us lose __iomem annotation and makes sparse unhappy. OTOH we do need to cast to (void *) when calculating xhci->dba from offset, but since it is IO memory we need to annotate it as such.

2011-02-20USB: xhci: rework xhci_print_ir_set() to get ir set from xhci itselfDmitry Torokhov
xhci->ir_set points to __iomem region, but xhci_print_ir_set accepts plain struct xhci_intr_reg * causing multiple sparse warning at call sites and inside the fucntion when we try to read that memory. Instead of adding __iomem qualifier to the argument let's rework the function so it itself gets needed register set from xhci and prints it.

2011-02-20xhci: Fix an error in count_sg_trbs_needed()Paul Zimmerman
The expression while (running_total < sg_dma_len(sg)) does not take into account that the remaining data length can be less than sg_dma_len(sg). In that case, running_total can end up being greater than the total data length, so an extra TRB is counted. Changing the expression to while (running_total < sg_dma_len(sg) && running_total < temp) fixes that. This patch should be queued for stable kernels back to 2.6.31.

2011-02-20xhci: Fix errors in the running total calculations in the TRB mathPaul Zimmerman
Calculations like running_total = TRB_MAX_BUFF_SIZE - (sg_dma_address(sg) & (TRB_MAX_BUFF_SIZE - 1)); if (running_total != 0) num_trbs++; are incorrect, because running_total can never be zero, so the if() expression will never be true. I think the intention was that running_total be in the range of 0 to TRB_MAX_BUFF_SIZE-1, not 1 to TRB_MAX_BUFF_SIZE. So adding a running_total &= TRB_MAX_BUFF_SIZE - 1; fixes the problem.

Note: This patch changes the expressions containing "((1 << TRB_MAX_BUFF_SHIFT) - 1)" to use the equivalent "(TRB_MAX_BUFF_SIZE - 1)". No change in behavior is intended for those expressions.

If we leave via the 'fail' label due to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope without having been assigned to anything, so we'll leak the memory we allocated.

2011-01-22USB: ehci-fsl: Fix 'have_sysif_regs' detectionPeter Tyser
Previously a check was done on an ID register at the base of a CPU's internal USB registers to determine if system interface regsiters were present. The check looked for an ID register that had the format ID[0:5] == ~ID[8:13] as described in the MPC5121 User's Manual to determine if a MPC5121 or MPC83xx/85xx was being used. There are two issues with this method: - The ID register is not defined on the MPC83xx/85xx CPUs, so its unclear what is being checked on them. - Newer CPUs such as the P4080 also don't document the ID register, but do share the same format as the MPC5121. Thus the previous code did not set 'have_sysif_regs' properly which results in the P4080 not properly initializing its USB ports. Using the device tree 'compatible' node is a cleaner way to determine if 'have_sysif_regs' should be set and resolves the USB initialization issue seen on the P4080. Tested on a P4080-based system and compile tested on mpc512x_defconfig with Freescale EHCI driver enabled.

This patch (as1440) fixes a bug in ehci-hcd. ehci->periodic_size is used to compute the size in a dma_alloc_coherent() call, but then it gets changed later on. As a result, the corresponding call to dma_free_coherent() passes a different size from the original allocation. Fix the problem by adjusting ehci->periodic_size before carrying out any of the memory allocations.

2011-01-14xhci: Resume bus on any port status change.Sarah Sharp
The original code that resumed the USB bus on a port status change would only do so when there was a device connected to the port. If a device was just disconnected, the event would be queued for khubd, but khubd wouldn't run. That would leave the connect status change (CSC) bit set. If a USB device was plugged into that same port, the xHCI host controller would set the current connect status (CCS) bit. But since the CSC bit was already set, it would not generate an interrupt for a port status change event. That would mean the user could "Safely Remove" a device, have the bus suspend, disconnect the device, re-plug it in, and then the device would never be enumerated. Plugging in a different device on another port would cause the bus to resume, and khubd would notice the re-connected device. Running lsusb would also resume the bus, leading users to report the problem "went away" when using diagnostic tools. The solution is to resume the bus when a port status change event is received, regardless of the port status. Thank you very much to Maddog for helping me track down this Heisenbug. This patch should be queued for the 2.6.37 stable tree.

2010-12-16USB: ehci-mxc: Setup portsc register prior to accessing OTG viewportFabio Estevam
In order to read/write to the i.MX OTG viewport register it is necessary to setup the PORTSCx register first. By default i.MX OTG port is configured for USB serial PHY. In order to use a ULPI PHY the PORTSCx register needs to be configured properly. commit 724c852 (USB: ehci/mxc: compile fix) placed the PORTSC setup after the OTG viewport is accessed and this causes ULPI read/write to fail. Revert the PORTSC setup order. Tested on a MX31PDK board with a ISP1504 transceiver: ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver mxc-ehci mxc-ehci.0: initializing i.MX USB Controller ULPI transceiver vendor/product ID 0x04cc/0x1504 Found NXP ISP1504 ULPI transceiver.

2010-12-10USB: EHCI: ASPM quirk of ISOC on AMD SB800Alex He
When ASPM PM Feature is enabled on UMI link, devices that use ISOC stream of data transfer may be exposed to longer latency causing less than optimal per- formance of the device. The longer latencies are normal and are due to link wake time coming out of low power state which happens frequently to save power when the link is not active. The following code will make exception for certain features of ASPM to be by passed and keep the logic normal state only when the ISOC device is connected and active. This change will allow the device to run at optimal performance yet minimize the impact on overall power savings.

2010-12-09xhci: Fix issue with port array setup and buggy hosts.Sarah Sharp
Fix two bugs with the port array setup. The first bug will only show up with broken xHCI hosts with Extended Capabilities registers that have duplicate port speed entries for the same port. The idea with the original code was to set the port_array entry to -1 if the duplicate port speed entry said the port was a different speed than the original port speed entry. That would mean that later, the port would not be exposed to the USB core. Unfortunately, I forgot a continue statement, and the port_array entry would just be overwritten in the next line. The second bug would happen if there are conflicting port speed registers (so that some entry in port_array is -1), or one of the hardware port registers was not described in the port speed registers (so that some entry in port_array is 0). The code that sets up the usb2_ports array would accidentally claim those ports. That wouldn't really cause any user-visible issues, but it is a bug. This patch should go into the stable trees that have the port array and USB 3.0 port disabling prevention patches. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@kernel.org
