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.

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

There is a demand from driver's writers to use managed devices framework
for their drivers. Unfortunately up to this moment input devices did not
provide support for managed devices and that lead to mixing two styles
of resource management which usually introduced more bugs, such as
manually unregistering input device but relying in devres to free
interrupt handler which (unless device is properly shut off) can cause
ISR to reference already freed memory.

This change introduces devm_input_allocate_device() that will allocate
managed instance of input device so that driver writers who prefer
using devm_* framework do not have to mix 2 styles.
