Linus Torvalds 1aae31c830 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov:
 "The main change is that we now publish "firmware ID" for the serio
  devices to help userspace figure out the kind of touchpads it is
  dealing with: i8042 will export PS/2 port's PNP IDs as firmware IDs.

  You will also get more quirks for Synaptics touchpads in various
  Lenovo laptops, a change to elantech driver to recognize even more
  models, and fixups to wacom and couple other drivers"

Alexander Stein 2fdf4cd9a2 Input: ads7846 - fix device usage within attribute show
With commit e585c40ba (Input: ads7846 - convert to
hwmon_device_register_with_groups()) the device passed to the attribute's
show function isn't the spi device as before.
So fixup the passed device to ads7846_read12_ser.

Rafael J. Wysocki 71d821fdae PM / QoS: Add type to dev_pm_qos_add_ancestor_request() arguments
Rework dev_pm_qos_add_ancestor_request() so that device PM QoS type
is passed to it as the third argument and make it support the
DEV_PM_QOS_LATENCY_TOLERANCE device PM QoS type (in addition to
DEV_PM_QOS_RESUME_LATENCY).

That will allow the drivers of devices without latency tolerance
hardware support to use their ancestors having it as proxies for
their latency tolerance requirements.

Luis Ortega d333b6062f Input: zforce - reduce stack memory allocated to frames
A frame is a u8 array with the following structure:
[PAYLOAD_HEADER, PAYLOAD_LENGTH, ...PAYLOAD_BODY...]

PAYLOAD_BODY can be at most 255 bytes long, as it's size is represented
by PAYLOAD_LENGTH. Therefore we can reduce the stack memory allocated to
payload_buffer[] roughly by half, from 512 to 257 bytes.

Luis Ortega 5aee41a60c Input: zforce - remove unnecessary payload data checks
The function zforce_read_packet() reads 2 values (bytes) of payload
header, validates them and then proceeds to read the payload body.
The function stores all these in a u8 buffer.

The PAYLOAD_LENGTH check seems to be trying to detect an overflow error.
However, since we are just reading a u8 value from the buffer, these
checks are unnecessary and we should simply compare against zero.

Sebastian Andrzej Siewior 7e170c6e4f mfd: ti_am335x_tscadc: Don't read back REG_SE
The purpose of reg_se_cache has been defeated. It should avoid the
read-back of the register to avoid the latency and the fact that the
bits are reset to 0 after the individual conversation took place.

The reason why this is required like this to work, is that read-back of
the register removes the bits of the ADC so they do not start another
conversation after the register is re-written from the TSC side for the
update.
To avoid the not required read-back I introduce a "set once" variant which
does not update the cache mask. After the conversation completes, the
bit is removed from the SE register anyway and we don't plan a new
conversation "any time soon". The current set function is renamed to
set_cache to distinguish the two operations.
This is a small preparation for a larger sync-rework.

handle_level_irq masks the interrupt before handling it, and only
unmasks it after the handler is finished. So when a touch event
happens after threads are suspended, but before the system is fully asleep
the irq handler tries to wakeup the thread which will only happen on the
next resume, resulting in the wakeup event never being sent and the driver
not being able to wake the system from sleep due to the masked irq.

Therefore move the wakeup_event to a small non-threaded handler.

Jingoo Han c838cb3d47 Input: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead
of accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

Christian Engelmayer 4ef38351d7 Input: usbtouchscreen - separate report and transmit buffer size handling
This patch supports the separate handling of the USB transfer buffer length
and the length of the buffer used for multi packet support. For devices
supporting multiple report or diagnostic packets, the USB transfer size is now
limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the
configured report packet size as before.

This fixes an issue where event reporting can be delayed for an arbitrary
time for multi packet devices. For instance the report size for eGalax devices
is defined to the 16 byte maximum diagnostic packet size as opposed to the 5
byte report packet size. In case the driver requests 16 byte from the USB
interrupt endpoint, the USB host controller driver needs to split up the
request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte.
When the first transfer is answered by the eGalax device with not less than
the full 8 byte requested, the host controller has got no way of knowing
whether the touch controller has got additional data queued and will issue
the second transfer. If per example a liftoff event finishes at such a
wMaxPacketSize boundary, the data will not be available to the usbtouch driver
until a further event is triggered and transfered to the host. From user
perspective the BTN_TOUCH release event in this case is stuck until the next
touch down event.

We will never use packet_id before initializing it as we start with

There was a spelling mistake on TSC/ADC binding where "coordinate" was
spelled as "coordiante".

We can't simply fix the error due to DT being an ABI, the approach taken
was to first use correct spelling and if that fails, fall back to
miss-spelled version.

It's unfortunate that has creeped into the tree.
