Revert "staging: nvec: ps2: change serio type to passthrough"

2016-11-24T15:23:45+00:00

commit 17c1c9ba15b238ef79b51cf40d855c05b58d5934 upstream.

This reverts commit 36b30d6138f4677514aca35ab76c20c1604baaad.

This is necessary to detect paz00 (ac100) touchpad properly as one
speaking ETPS/2 protocol. Without it X.org's synaptics driver doesn't
work as the touchpad is detected as an ImPS/2 mouse instead.

Commit ec6184b1c717b8768122e25fe6d312f609cc1bb4 changed the way
auto-detection is performed on ports marked as pass through and made the
issue apparent.

A pass through port is an additional PS/2 port used to connect a slave
device to a master device that is using PS/2 to communicate with the
host (so slave's PS/2 communication is tunneled over master's PS/2
link). "Synaptics PS/2 TouchPad Interfacing Guide" describes such a
setup (PS/2 PASS-THROUGH OPTION section).

Since paz00's embedded controller is not connected to a PS/2 port
itself, the PS/2 interface it exposes is not a pass-through one.

drivers: staging: nvec: remove bogus reset command for PS/2 interface

2016-11-24T15:23:44+00:00

commit d8f8a74d5fece355d2234e1731231d1aebc66b38 upstream.

This command was sent behind serio's back and the answer to it was
confusing atkbd probe function which lead to the elantech touchpad
getting detected as a keyboard.

To prevent this from happening just let every party do its part of the
job.

staging: nvec: re-enable the clock on resume

2013-07-29T18:29:37+00:00

On resume the slave controller is reinitialized. The tegra i2c master
controller disables the clock at the end of the initialiation, propably
to save some power, and enables it again on each transfer. We don't
do this yet and also forgot to enable the clock on resume. Fix this
copy-paste error by not disabling the clock after initialization.

This didn't striked us yet because suspend/resume hasn't landed in mainline
yet, but will soon.
