linux.git/drivers/input/mouse, branch v4.0-rc2

Input: psmouse - use IS_ENABLED instead of homegrown code

2015-02-16T00:08:35+00:00

Instead of having various protocols provide _supported()
functions, let's use IS_ENABLED() macro that works well in "if" statements.

Merge bfin_rotary driver changes from Sonic Zhang.

Input: ALPS - move v7 packet info to Documentation and v6 packet info

2015-02-16T00:04:23+00:00

This patch move all packet info from driver source code to documentation
and adds info about v6 packet format (from driver source code).

Input: ALPS - fix confusing comment in protocol data

2015-02-16T00:04:23+00:00

The comment about suspicions entry 0x20, 0x02, 0x0e has over time drifted
away and it become hard to figure out what it meant. Let's move it back so
it is clear.

Input: ALPS - do not mix trackstick and external PS/2 mouse data

2015-02-15T23:44:19+00:00

Previously dev2 device was used for both external PS/2 mouse and internal
trackstick device (if available). This change introduces dev3 device which
is used for external PS/2 mouse data and dev2 is now used only for
trackstick.

In case that trackstick is not present dev2 is not created, so userspace
does not see non existent device in system.

Because laptops with ALPS devices often do not use i8042 active
multiplexing all data (from touchpad, trackstick and external PS/2 mouse)
come to one port.  So it is not possible to know if external PS/2 mouse is
connected or not. In most cases external PS/2 mouse is not connected so
driver will create dev3 input device after first bare PS/2 packet will be
received. So there will not be "ghost" input device.

This change also helps in identifying possible problems in future if driver
decides to report 6-bytes trackstick packets as 3-bytes bare PS/2 (data
will be reported to dev3 instead dev2).

Input: ALPS - fix trackstick detection on some Dell Latitudes

2015-02-15T23:44:18+00:00

On some Dell Latitudes we fail to identify presence of trackstick unless we
reset the device. The issue is quite benign as we do perform reset in
alps_init(), so the trackstick ends up working, but mouse name reported to
userspace is not accurate.

In order to fix the issue while avoiding the additional lengthy reset we
move the resrt to alps_detect() and keep the discovered state to be used
later in alps_init().

Input: ALPS - consolidate setting protocol parameters

2015-02-15T23:44:18+00:00

Move setting of all protocol properties into alps_set_protocol (former
alps_set_defaults) instead of having it split between several functions.

Input: ALPS - split protocol data from model info

2015-02-15T23:44:17+00:00

In preparation of reworking the way we set protocol parameters let's
split certain protocol items from alps_model_info into a separate
structure.

Input: ALPS - make Rushmore a separate protocol

2015-02-15T23:44:17+00:00

Even though Rushmore is very close to V3 protocol it is sufficiently
different to warrant it's own protocol name.

Input: ALPS - renumber protocol numbers

2015-02-15T23:44:16+00:00

In order to accommodate new protocol number for Rushmore touchpads
let's shift protocol numbers by 8 bits (i.e. 1 -> 0x100) - this way
we keep protocol version reported in input device id the same as it
was, but add some holes in numbering.
