Subject: [PATCH v6 0/2] add support for the Samsung S6SY761 touchscreen

Hi,

This patchset adds support for the Samsung s6sy761 touchscreen.

Thanks,
Andi

v5 - v6
 - make a clear logical split between hw initialization and
   resume.
 - fix an inconsistency when applying the maximum x and y
   coordinates (as discussed with Dmitry[*]).

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()'
