Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

2015-04-21T19:54:08+00:00

Pull more input subsystem updates from Dmitry Torokhov:

 - an update to Atmel MXT driver that makes it functional on Google
   Pixel 2 boxes (both touchpad and touchscreen)

 - a new VMware VMMouse driver that should allow us drop X vmmouse
   driver that requires root privileges (since it accesses ioports)

 - XBox One controllers now support force feedback (rumble)

  Input: lm8333 - fix broken email address
  Input: cyapa - fix setting suspend scan rate
  Input: elan_i2c - fix calculating number of x and y traces.
  Input: elan_i2c - report hovering contacts
  Input: elants_i2c - zero-extend hardware ID in firmware name

Merge branch 'drm-next-merged' of git://people.freedesktop.org/~airlied/linux into v4l_for_linus

2015-04-21T12:44:55+00:00

* 'drm-next-merged' of git://people.freedesktop.org/~airlied/linux: (9717 commits)
  media-bus: Fixup RGB444_1X12, RGB565_1X16, and YUV8_1X24 media bus format
  hexdump: avoid warning in test function
  fs: take i_mutex during prepare_binprm for set[ug]id executables
  smp: Fix error case handling in smp_call_function_*()
  iommu-common: Fix PARISC compile-time warnings
  sparc: Make LDC use common iommu poll management functions
  sparc: Make sparc64 use scalable lib/iommu-common.c functions
  Break up monolithic iommu table/lock into finer graularity pools and lock
  sparc: Revert generic IOMMU allocator.
  tools/power turbostat: correct dumped pkg-cstate-limit value
  tools/power turbostat: calculate TSC frequency from CPUID(0x15) on SKL
  tools/power turbostat: correct DRAM RAPL units on recent Xeon processors
  tools/power turbostat: Initial Skylake support
  tools/power turbostat: Use $(CURDIR) instead of $(PWD) and add support for O= option in Makefile
  tools/power turbostat: modprobe msr, if needed
  tools/power turbostat: dump MSR_TURBO_RATIO_LIMIT2
  tools/power turbostat: use new MSR_TURBO_RATIO_LIMIT names
  Bluetooth: hidp: Fix regression with older userspace and flags validation
  config: Enable NEED_DMA_MAP_STATE by default when SWIOTLB is selected
  perf/x86/intel/pt: Fix and clean up error handling in pt_event_add()
  ...

That solves several merge conflicts:
	Documentation/DocBook/media/v4l/subdev-formats.xml
	Documentation/devicetree/bindings/vendor-prefixes.txt
	drivers/staging/media/mn88473/mn88473.c
	include/linux/kconfig.h
	include/uapi/linux/media-bus-format.h

The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.

Input: elants_i2c - zero-extend hardware ID in firmware name

2015-04-20T17:28:21+00:00

Let's zero-extend hardware id number when forming firmware file name,
to avoid kernel requesting firmware like "elants_i2c_   0.bin", which
is quite unexpected.

Input: atmel_mxt_ts - add support for Google Pixel 2

2015-04-15T17:52:48+00:00

This change allows atmel_mxt_ts to bind to ACPI-enumerated devices in
Google Pixel 2 (2015).

While newer version of ACPI standard allow use of device-tree-like
properties in device descriptions, the version of ACPI implemented in
Google BIOS does not support them, and we have to resort to DMI data to
specify exact characteristics of the devices (touchpad vs. touchscreen,
GPIO to button mapping, etc).

Pixel 1 continues to use i2c devices and platform data created by
chromeos-laptop driver, since ACPI does not enumerate them.

[media] sur40: fix occasional hard freeze due to buffer queue underrun

2015-04-08T09:28:56+00:00

This patch fixes a kernel panic which occurs when buf_list is empty. This can
happen occasionally when user space is under heavy load (e.g. due to image
processing on the CPU) and new buffers aren't re-queued fast enough. In that
case, vb2_start_streaming_called can return true, but when the spinlock
is taken and sur40_poll attempts to fetch the next buffer from buf_list, the
list is in fact empty.

This patch needs to be applied on top of the queued one adding V4L2 support
to the sur40 driver.

Input: atmel_mxt_ts - split out touchpad initialisation logic

2015-04-06T20:37:32+00:00

If the "linux,gpio-keymap" DT property is defined, the T19 keys are
configured and the device is setup as a touchpad rather than a touchscreen.
The logic is part of the input device initialization routine but it can be
factored out to its own function to simplify the former.

Input: atmel_mxt_ts - implement support for T100 touch object

2015-04-06T20:37:31+00:00

Add support for the new T100 object which replaces the previous T9
multitouch touchscreen object in recent maXTouch devices. T100 provides
improved reporting with selectable auxiliary information, and a type field
for hover/stylus/glove reporting.

The hovering finger support was based on Chung-Yih's work in the ChromiumOS
downstream kernel:

[media] add raw video stream support for Samsung SUR40

2015-04-03T00:16:03+00:00

This patch adds raw video support for the Samsung SUR40 using vbuf2-dma-sg.
All tests from v4l2-compliance pass. Support for VB2_USERPTR is currently
disabled due to unexpected interference with dma-sg buffer sizes.

input_register_device already sets the EV_SYN event since all devices can
generate them.

Remove the redundant affectation.
