Colin Ian King ea38f06e02 Input: sentelic - fix error return when fsp_reg_write fails 
Currently when the call to fsp_reg_write fails -EIO is not being returned
because the count is being returned instead of the return value in retval.
Fix this by returning the value in retval instead of count.

Jingle Wu 04d5ce620f Input: elan_i2c - add support for high resolution reports 
Newer controllers (identified as "pattern" version 2) send higher
resolution reports, with 16-bit X and Y coordinates (previous generations
used 12-bit values). These new high resolution reports use report ID of
0x60.

SMbus controllers use the same buffer size for both the new and old
reports, and because of that high resolution reports no longer carry
area of contact data with SMbus.

Jingle Wu fc7c882aa9 Input: elan_i2c - make fetching IC type of older controllers more robust 
On older controllers IC type is reported in the 2nd byte of
ETP_I2C_OSM_VERSION_CMD, however if controller's firmware is not flashed
correctly it may return incorrect data. Fortunately there is also
ETP_I2C_IAP_VERSION_P0_CMD command that can be used when controller in
either normal or IAP mode, and which is guaranteed to return accurate data,
so let's use it.

Derek Basehore 966334dfc4 Input: elan_i2c - only increment wakeup count on touch 
This moves the wakeup increment for elan devices to the touch report.
This prevents the drivers from incorrectly reporting a wakeup when the
resume callback resets then device, which causes an interrupt to
occur.
