These touchpads use a different protocol; they have been seen on Dell

The official ALPS driver identifies them by looking for an exact match
on the E7 report: 73 03 50. Dolphin V1 returns an EC report of
73 01 xx (02 and 0d have been seen); Dolphin V2 returns an EC report of
73 02 xx (02 has been seen).
Dolphin V2 probably needs a different initialization sequence and/or

Input: synaptics - fix 1->3 contact transition reporting
Investigating the following gesture highlighted two slight implementation
errors with choosing which slots to report in which slot when multiple
contacts are present:
Action SGM AGM (MTB slot:Contact)
1. Touch contact 0 (0:0)
2. Touch contact 1 (0:0, 1:1)
3. Lift contact 0 (1:1)
4. Touch contacts 2,3 (0:2, 1:3)
In step 4, slot 1 was not being cleared first, which means the same
tracking ID was being used for reporting both the old contact 1 and the
new contact 3. This could result in "drumroll", where the old contact 1
would appear to suddenly jump to new finger 3 position.
Similarly, if contacts 2 & 3 are not detected at the same sample, step 4
is split into two:
Action SGM AGM (MTB slot:contact)
1. Touch contact 0 (0:0)
2. Touch contact 1 (0:0, 1:1)
3. Lift contact 0 (1:1)
4. Touch contact 2 (0:2, 1:1)
5. Touch contact 3 (0:2, 1:3)
In this case, there was also a bug. In step 4, when contact 1 moves from
SGM to AGM and contact 2 is first reported in SGM, slot 0 was actually
empty. So slot 0 can be used to report the new SGM (contact 0),
immediately. Since it was empty, contact 2 in slot 0 will get a new
tracking ID.

Input: atkbd - fix multi-byte scancode handling on reconnect
On resume from suspend there is a possibility for multi-byte scancodes
to be handled incorrectly. atkbd_reconnect disables the processing of
scancodes in software by calling atkbd_disable, but the keyboard may
still be active because no disconnect command was sent. Later, software
handling is re-enabled. If a multi-byte scancode sent from the keyboard
straddles the re-enable, only the latter byte(s) will be handled.
In practice, this leads to cases where multi-byte break codes (ex. "e0
4d" - break code for right-arrow) are misread as make codes ("4d" - make
code for numeric 6), leading to one or more unwanted, untyped characters
being interpreted.
The solution implemented here involves sending command f5 (reset
disable) to the keyboard prior to disabling software handling of codes.
Later, the command to re-enable the keyboard is sent only after we are
prepared to handle scancodes.

Henrik added new MT routines in release 3.7. This patch is to prepare
for the use of new MT routines.
In the newly added wacom_abs_set_axis() function, the first
if-statement assigns ABS_X/Y for number of contacts less or equal
to 2. So, it is single and 2 finger touch devices. Two finger touch
devices are processed here since they will not use the updated
input_mt_init_slots(), which does not offer benefit to those devices.
input_mt_init_slots() will take care of ABS_X/Y assignment when flags
are not zero. All touch devices with more than two contacts will use
input_mt_init_slots() with non-zero flags.
The second if-statement is for all MT devices, which include two
finger touch devices.

Input: stmpe-keypad - add support for Device Tree bindings
This patch allows the STMPE driver to be successfully probed and
initialised when Device Tree support is enabled. Besides the usual
platform data changes, we also separate the process of filling in
the 'in use' pin bitmap, as we have to extract the information from
Device Tree in the DT boot case.
