2011-05-29x86 idle floppy: deprecate disable_hlt()Len Brown
Plan to remove floppy_disable_hlt in 2012, an ancient workaround with comments that it should be removed. This allows us to remove clutter and a run-time branch from the idle code.

2011-05-29x86 idle: clarify AMD erratum 400 workaroundLen Brown
The workaround for AMD erratum 400 uses the term "c1e" falsely suggesting: 1. Intel C1E is somehow involved 2. All AMD processors with C1E are involved Use the string "amd_c1e" instead of simply "c1e" to clarify that this workaround is specific to AMD's version of C1E. Use the string "e400" to clarify that the workaround is specific to AMD processors with Erratum 400.

2011-05-29ACPI: Add D3 cold stateLin Ming
_SxW returns an Integer containing the lowest D-state supported in state Sx. If OSPM has not indicated that it supports _PR3, then the value “3” corresponds to D3. If it has indicated _PR3 support, the value “3” represents D3hot and the value “4” represents D3cold. Linux does set _OSC._PR3, so we should fix it to expect that _SxW can return 4.

2011-05-29ACPI: processor: fix processor_physically_present in UP kernelLin Ming
Usually, there are multiple processors defined in ACPI table, for example Scope (_PR) { Processor (CPU0, 0x00, 0x00000410, 0x06) {} Processor (CPU1, 0x01, 0x00000410, 0x06) {} Processor (CPU2, 0x02, 0x00000410, 0x06) {} Processor (CPU3, 0x03, 0x00000410, 0x06) {} } processor_physically_present(...) will be called to check whether those processors are physically present. Currently we have below codes in processor_physically_present, cpuid = acpi_get_cpuid(...); if ((cpuid == -1) && (num_possible_cpus() > 1)) return false; return true; In UP kernel, acpi_get_cpuid(...) always return -1 and num_possible_cpus() always return 1, so processor_physically_present(...) always returns true for all passed in processor handles. This is wrong for UP processor or SMP processor running UP kernel. This patch removes the !SMP version of acpi_get_cpuid(), so both UP and SMP kernel use the same acpi_get_cpuid function. And for UP kernel, only processor 0 is valid. https://bugzilla.kernel.org/show_bug.cgi?id=16548 https://bugzilla.kernel.org/show_bug.cgi?id=16357 Tested-by: Anton Kochkov <anton.kochkov@gmail.com> Tested-by: Ambroz Bizjak <ambrop7@gmail.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2011-05-27Intel xhci: Limit number of active endpoints to 64.Sarah Sharp
The Panther Point chipset has an xHCI host controller that has a limit to the number of active endpoints it can handle. Ideally, it would signal that it can't handle anymore endpoints by returning a Resource Error for the Configure Endpoint command, but they don't. Instead it needs software to keep track of the number of active endpoints, across configure endpoint commands, reset device commands, disable slot commands, and address device commands. Add a new endpoint context counter, xhci_hcd->num_active_eps, and use it to track the number of endpoints the xHC has active. This gets a little tricky, because commands to change the number of active endpoints can fail. This patch adds a new xHCI quirk for these Intel hosts, and the new code should not have any effect on other xHCI host controllers. Fail a new device allocation if we don't have room for the new default control endpoint. Use the endpoint ring pointers to determine what endpoints were active before a Reset Device command or a Disable Slot command, and drop those once the command completes. Fail a configure endpoint command if it would add too many new endpoints. We have to be a bit over zealous here, and only count the number of new endpoints to be added, without subtracting the number of dropped endpoints. That's because a second configure endpoint command for a different device could sneak in before we know if the first command is completed. If the first command dropped resources, the host controller fails the command for some reason, and we're nearing the limit of endpoints, we could end up oversubscribing the host. To fix this race condition, when evaluating whether a configure endpoint command will fix in our bandwidth budget, only add the new endpoints to xhci->num_active_eps, and don't subtract the dropped endpoints. Ignore changed endpoints (ones that are dropped and then re-added), as that shouldn't effect the host's endpoint resources. When the configure endpoint command completes, subtract off the dropped endpoints. This may mean some configuration changes may temporarily fail, but it's always better to under-subscribe than over-subscribe resources. (Originally my plan had been to push the resource allocation down into the ring allocation functions. However, that would cause us to allocate unnecessary resources when endpoints were changed, because the xHCI driver allocates a new ring for the changed endpoint, and only deletes the old ring once the Configure Endpoint command succeeds. A further complication would have been dealing with the per-device endpoint ring cache.) Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
2011-05-27Intel xhci: Ignore spurious successful event.Sarah Sharp
The xHCI host controller in the Panther Point chipset sometimes produces spurious events on the event ring. If it receives a short packet, it first puts a Transfer Event with a short transfer completion code on the event ring. Then it puts a Transfer Event with a successful completion code on the ring for the same TD. The xHCI driver correctly processes the short transfer completion code, gives the URB back to the driver, and then prints a warning in dmesg about the spurious event. These warning messages really fill up dmesg when an HD webcam is plugged into xHCI. This spurious successful event behavior isn't technically disallowed by the xHCI specification, so make the xHCI driver just ignore the spurious completion event. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
2011-05-27Intel xhci: Support EHCI/xHCI port switching.Sarah Sharp
The Intel Panther Point chipsets contain an EHCI and xHCI host controller that shares some number of skew-dependent ports. These ports can be switched from the EHCI to the xHCI host (and vice versa) by a hardware MUX that is controlled by registers in the xHCI PCI configuration space. The USB 3.0 SuperSpeed terminations on the xHCI ports can be controlled separately from the USB 2.0 data wires. This switchover mechanism is there to support users who do a custom install of certain non-Linux operating systems that don't have official USB 3.0 support. By default, the ports are under EHCI, SuperSpeed terminations are off, and USB 3.0 devices will show up under the EHCI controller at reduced speeds. (This was more palatable for the marketing folks than having completely dead USB 3.0 ports if no xHCI drivers are available.) Users should be able to turn on xHCI by default through a BIOS option, but users are happiest when they don't have to change random BIOS settings. This patch introduces a driver method to switchover the ports from EHCI to xHCI before the EHCI driver finishes PCI enumeration. We want to switch the ports over before the USB core has the chance to enumerate devices under EHCI, or boot from USB mass storage will fail if the boot device connects under EHCI first, and then gets disconnected when the port switches over to xHCI. Add code to the xHCI PCI quirk to switch the ports from EHCI to xHCI. The PCI quirks code will run before any other PCI probe function is called, so this avoids the issue with boot devices. Another issue is with BIOS behavior during system resume from hibernate. If the BIOS doesn't support xHCI, it may switch the devices under EHCI to allow use of the USB keyboard, mice, and mass storage devices. It's supposed to remember the value of the port routing registers and switch them back when the OS attempts to take control of the xHCI host controller, but we all know not to trust BIOS writers. Make both the xHCI driver and the EHCI driver attempt to switchover the ports in their PCI resume functions. We can't guarantee which PCI device will be resumed first, so this avoids any race conditions. Writing a '1' to an already set port switchover bit or a '0' to a cleared port switchover bit should have no effect. The xHCI PCI configuration registers will be documented in the EDS-level chipset spec, which is not public yet. I have permission from legal and the Intel chipset group to release this patch early to allow good Linux support at product launch. I've tried to document the registers as much as possible, so please let me know if anything is unclear. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

2011-05-27USB: TWL6025 allow different regulator nameGraeme Gregory
The twl6025 uses a different regulator for USB than the 6030 so select the correct regulator name depending on the subclass of device. Since V1 Use features passed via platform data instead of global variable.

2011-05-27REGULATOR: TWL6025: add support to twl-regulatorGraeme Gregory
Adding support for the twl6025. Major difference in the twl6025 is the group functionality has been removed from the chip so this affects how regulators are enabled and disabled. The names of the regulators also changed. The DCDCs of the 6025 are software controllable as well. Since V1 Use the features variable passed via platform data instead of calling global function. Change the very switch like if statements to be a more readable switch statement. Since V2 twl6025 doesn't use remap so remove it from the macros. Since V3 enable/disable functions for 4030/6030 were seperated upstream so rebase on top of this. Change DCDC reference to SMPS as this is used in TRM. Change list_voltage slightly to have less code.
