e4b88e1989 Input: stmpe-ts - enforce device tree only mode
The STMPE MFD is only used with device tree configured systems (and STMPE
MFD core depends on OF), so force the configuration to come from device
tree only.

77b071e793 Input: smtpe-ts - wait 50mS until polling for pen-up
Wait a little bit longer, 50mS instead of 20mS, until the driver starts
polling for pen-up. The problematic behavior before this patch is applied
is as follows. The behavior was observed on the STMPE610QTR controller.

Upon a physical pen-down event, the touchscreen reports one set of x-y-p
coordinates and a pen-down event. After that, the pen-up polling is
triggered and since the controller is not ready yet, the polling mistakenly
detects a pen-up event while the physical state is still such that the pen
is down on the touch surface.

The pen-up handling flushes the controller FIFO, so after that, all the
samples in the controller are discarded. The controller becomes ready
shortly after this bogus pen-up handling and does generate again a pen-down
interrupt. This time, the controller contains x-y-p samples which all read
as zero. Since pressure value is zero, this set of samples is effectively
ignored by userland.

In the end, the driver just bounces between pen-down and bogus pen-up
handling, generating no useful results. Fix this by giving the controller a
bit more time before polling it for pen-up.

3a38958d24 Input: adxl34x - add OF match support
The I2C subsystem can match devices without explicit OF support based on
the part of their compatible property after the comma. However, this
mechanism uses the first compatible value only. For adxl34x OF device
nodes the compatible property will contain the more specific
"adi,adxl345" or "adi,adxl346" value first. This prevents the device
node from being matched with the adxl34x driver.

Fix this by adding an OF match table with an "adi,adxl345" compatible
entry. There's no need to add the "adi,adxl346" entry as the ADXL346 is
backward-compatible with the ADXL345 with differences handled by runtime
detection of the device model.

Joydev is currently thinking some absolute mice are joystick, and that
messes up games in VMware guests, as the cursor typically gets stuck in
the top left corner.

Try to detect the event signature of a VMmouse input device and back off
for such devices. We're still incorrectly detecting, for example, the
VMware absolute USB mouse as a joystick, but adding an event signature
matching also that device would be considerably more risky, so defer that
to a later merge window.

72eceab743 Input: alps - fix finger jumps on lifting 2 fingers on v7 touchpad
On v7 touchpads sometimes when 2 fingers are moved down on the touchpad
until they "fall of" the touchpad, the second touch will report 0 for y
(max y really since the y axis is inverted) and max x as coordinates,
rather then reporting 0, 0 as is expected for a non touching finger.

This commit detects this and treats these touches as non touching.

4dd2657307 Input: alps - use more accurate coordinates for first touch in semi-mt mode
All alps semi-mt touchpads give us the following data when 2 (or more)
fingers are touching: 1 more or less accurate touch for the first finger
down, and a bitmap with columns and rows in which 1 or more fingers are
seen resulting in a crude (low res) bounding box.

So far for v3, rushmore and v4 touchpads we've been reporting the
coordinates of 2 opposite corners of the box when 2 fingers are touching.
Ignoring the much better resolution data given in the normal position
packet.

This commit actually uses this data for the first touch, figures out which
corner of the bounding box is closest to the first touch, and reports the
coordinates of the opposite corner for the second touch, resulting in
much better data for the first touch and for the single touch
pointer-emulation events.

This approach is similar to the one in alps_process_bitmap_dolphin, that
function takes the single accurate touch info, calculates the distance to
the center of the bounding box, and then puts the 2nd touch mirrored to
the center. The downside of that approach is that if both touches move
slowly in the same direction, the bounding box will stay the same for a
while (as it is low res) and the second touch will thus been seen moving
in the opposite direction until the bounding box actually changes, and
then the second touch snaps to its new position resulting in a saw tooth
pattern in the coordinates for the second touch, hence this new approach.

This commit fixes 2 finger scrolling being choppy / jumpy on these
touchpads.

a839cd579b Input: alps - only set fields that are actually present
Pinnacle / Rushmore packets contain either position info, or bitmap info,
never both. So far we've in essence been storing garbage in the position /
bitmap fields of the fields struct when decoding a bitmap / pos packet.

We've been relying on the following sequence to get away with this:

1) Decode bitmap packet
2) Process bitmap packet
3) Decode position packet
4) Use position / button info

This patch allows us to change this sequence, which will allow using the
position info when processing the bitmap for more accurate results.

0 - INT cleared when FIFO empty,
1 - INT cleared after host read. In this mode, I2C should read

So, if we set this flag, we have to read FIFO until it becomes empty. But
in interrupt we read FIFO just once.  This lead to "keyboard" hang until
reboot, if we press several keys, because of interrupt handler read just
one "press" from FIFO and clear interrupt.

c615dcb6d1 Input: adp5589-keys - fix event count mask
The event mask was specified as 0xF (4 bits) when in reality is 0x1F (5
bits) in order to be capable of representing all FIFO length values from
0 to 16.

This caused a problem: when the keypad reported 16 pending events the
driver took it as 0, and did nothing. This in turn caused the keypad to
re-issue the interrupt over and over again.

Guido Martínez
195e610bf7 Input: adp5589-keys - fix pull mask setting
The pull mask is created by looping each row (column) and building an
8-bit integer with the configuration. It is written byte-by-byte, when
we reach the end of the rows (columns) or we're at the 3rd line (which
finishes the first byte, since each pin is 2bits on the mask).

However, this only works if we have at most 8 pins (2 bytes), which is
not the case for the ADP5589. So, write the byte at each boundary (every
4 rows/columns).

429b474990 tty: remove buf parameter from tty_name()
tty_name no longer uses the buf parameter, so remove it along with all
the 64 byte stack buffers that used to be passed in.

Mostly generated by the coccinelle script

@depends on patch@
identifier buf;
constant C;
expression tty;
@@
- char buf[C];
  <+...
- tty_name(tty, buf)
+ tty_name(tty)
  ...+>

allmodconfig compiles, so I'm fairly confident the stack buffers
weren't used for other purposes as well.

TOUCHSCREEN_SUR40 selects VIDEOBUF2_DMA_SG, which bypasses its

this.

36a8032d77 platform/chrome: Updates for v4.1
Here's a set of updates to the Chrome OS platform drivers for this merge window.
 
 Main new things this cycle is:
 
 - Driver changes to expose the lightbar to users. With this, you can make your
   own blinkenlights on Chromebook Pixels.
 - Changes in the way that the atmel_mxt trackpads are probed. The laptop driver
   is trying to be smart and not instantiate the devices that don't answer to
   probe. For the trackpad that can come up in two modes (bootloader or regular),
   this gets complicated since the driver already knows how to handle the two
   modes including the actual addresses used. So now the laptop driver needs to
   know more too, instantiating the regular address even if the bootloader one
   is the probe that passed.
 - mfd driver improvements by Javier Martines Canillas, and a few bugfixes
   from him, kbuild and myself.

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