Hi,

This patchset adds support for the Samsung s6sy761 touchscreen.

Thanks,
Andi

v4 - v5
- The previous patch has been split in two parts as requested
by Rob and added his ack in the dt-binding patch.
- I tried to fix all the reviews from Dmitry[*]
- other random cleanups

v3 - v4
- fixed a mismatch on the module name

v2 - v3
- added security check on an unsigned value which can (unlikely)
get a "negative" value

- in the probe function the interrupt is requested after the
input device registration in order to avoid checking in the
interrupt handler whether the input device has been registered

- removed the 'prev_pm_state' variable. Its original meaning
was to restore the state of the device when coming back from
sleep mode, but because I removed in patch v2 the low power
mode, now the device works only in two modes and therefore
'prev_pm_state' is not required any longer.

v1 - v2
- remove the low power functionality as it doesn't bring any
benefit
- use get_unaligned_be16 instead of the form 'a << 8 | b'
- use max_t instead of '? :'
- use managed 'devm_device_add_group()'
