2014-09-24gpio / ACPI: Use pin index and bit lengthSrinivas Pandruvada1-1/+4
Fix code when the operation region callback is for an gpio, which is not at index 0 and for partial pins in a GPIO definition. For example: Name (GMOD, ResourceTemplate () { //3 Outputs that define the Power mode of the device GpioIo (Exclusive, PullDown, , , , "\\_SB.GPI2") {10, 11, 12} }) } If opregion callback calls is for: - Set pin 10, then address = 0 and bit length = 1 - Set pin 11, then address = 1 and bit length = 1 - Set for both pin 11 and pin 12, then address = 1, bit length = 2 This change requires updated ACPICA gpio operation handler code to send the pin index and bit length.

2014-09-24ACPICA: Update to GPIO region handler interface.Bob Moore6-16/+104
Changes to correct several GPIO issues: 1) The update_rule in a GPIO field definition is now ignored; a read-modify-write operation is never performed for GPIO fields. (Internally, this means that the field assembly/disassembly code is completely bypassed for GPIO.) 2) The Address parameter passed to a GPIO region handler is now the bit offset of the field from a previous Connection() operator. Thus, it becomes a "Pin Number Index" into the Connection() resource descriptor. 3) The bit_width parameter passed to a GPIO region handler is now the exact bit width of the GPIO field. Thus, it can be interpreted as "number of pins". Overall, we can now say that the region handler interface to GPIO handlers is a raw "bit/pin" addressed interface, not a byte-addressed interface like the system_memory handler interface.

2014-09-24ACPI / platform / LPSS: disable async suspend/resume of LPSS devicesFu Zhonghui1-1/+0
On some systems (Asus T100 in particular) there are strict ordering dependencies between LPSS devices with respect to power management that break if they suspend/resume asynchronously. In theory it should be possible to follow those dependencies in the async suspend/resume case too (the ACPI tables tell as that the dependencies are there), but since we're missing infrastructure for that at the moment, disable async suspend/resume for all of the LPSS devices for the time being.

But the flag is only set in the cpufreq_suspend() for cpufreq drivers which have target or target_index callback. This skips intel_pstate driver.

2014-09-21ACPI / hotplug: Generate online uevents for ACPI containersRafael J. Wysocki3-0/+12
Commit 46394fd01 (ACPI / hotplug: Move container-specific code out of the core) removed the generation of "online" uevents for containers, because "add" uevents are now generated for them automatically when container system devices are registered. However, there are user space tools that need to be notified when the container and all of its children have been enumerated, which doesn't happen any more. For this reason, add a mechanism allowing "online" uevents to be generated for ACPI containers after enumerating the container along with all of its children.

2014-09-19USB: storage: Add quirks for Entrega/Xircom USB to SCSI convertersMark1-0/+20
This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB- SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

2014-09-19USB: storage: Add quirk for Ariston Technologies iConnect USB to SCSI adapterMark1-0/+6
Hi, The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g. iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM Microsystems chips. Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use.

2014-09-19USB: EHCI: unlink QHs even after the controller has stoppedAlan Stern1-2/+0
Old code in ehci-hcd tries to expedite disabling endpoints after the controller has stopped, by destroying the endpoint's associated QH without first unlinking the QH. This was necessary back when the driver wasn't so careful about keeping track of the controller's state. But now we are careful about it, and the driver knows that when the controller isn't running, no unlinking delay is needed. Furthermore, skipping the unlink step will trigger a BUG() in qh_destroy() when the preceding QH is released, because the link pointer will be non-NULL. Removing the lines that skip the unlinking step and go directly to QH_STATE_IDLE fixes the problem.

When ending a bi-directionional SCSI request, blk_finish_request() cleans up and frees the request, but scsi_release_bidi_buffers() tries to indirect through the request to find it's data buffers. This causes a panic due to a null pointer dereference. Move the call to scsi_release_bidi_buffers() before the call to blk_finish_request().
