Input: wacom - add support for three new ISDv4 sensors

2014-05-15T01:47:09+00:00

This patch adds support for the 0x4004, 0x5000, and 0x5002 sensors found
on what should be the Motion R12, Fujitsu Q704, and Fujitsu T904. These
tablets use a new report ID (3) for their touch packets and a slightly
different HID descriptor format, but are otherwise largely identical in
protocol to the "MTTPC" tablets.

Note:
 * The R12 uses its 0x4004 sensor for touch input only. A pen interface
   is not present in its HID descriptor, though its possible a 0x4004
   may be used for pen input by other tablet PCs in the future.

 * The 0x5002 sensor appears to use a new report ID (8) for its pen
   packets. The other sensors continue to use the traditional report
   ID (2).

Input: wacom - use unaligned access where necessary

2014-05-15T01:47:08+00:00

A few cases of incorrectly using 'le16_to_cpup' instead of
'get_unaligned_le16' have been noticed and fixed.

Merge tag 'v3.15-rc5' into next

Merge with Linux 3.15-rc5 to sync up Wacom and other changes.

Input: wacom - add support for 0x116 sensor on Win8 Panasonic CF-H2

2014-05-14T23:40:07+00:00

The Win8 version of the Panasonic CF-H2 includes a new Wacom device.
The pen interface appears to use the same protocol as before, but the
touch interface has been tweaked to send Win8-compatible reports.

Input: wacom - handle 1024 pressure levels in wacom_tpc_pen

2014-04-19T20:57:35+00:00

Some tablet PC sensors (e.g. the 0xEC found in the Thinkpad Yoga) report
more than 256 pressure levels and will experience wraparound unless the
full range is read.

Input: wacom - references to 'wacom->data' should use 'unsigned char*'

2014-04-19T20:57:35+00:00

'wacom->data' contains raw binary data and can lead to unexpected behavior
if a byte under examination happens to have its MSB set.

Input: wacom - override 'pressure_max' with value from HID_USAGE_PRESSURE

2014-04-19T20:57:34+00:00

The 0xEC sensor is used in multiple tablet PCs and curiously has versions
that report 256 levels of pressure (Samsung Slate 7) as well as versions
that report 1024 levels (Lenovo Thinkpad Yoga).  To allow both versions to
work properly, we allow the value of HID_USAGE_PRESSURE reported to
override pressure_max.

Input: wacom - use full 32-bit HID Usage value in switch statement

2014-04-19T20:57:34+00:00

A HID Usage is a 32-bit value: an upper 16-bit "page" and a lower 16-bit
ID. While the two halves are normally reported seperately, only the
combination uniquely idenfifes a particular HID Usage.

The existing code performs the comparison in two steps, first performing a
switch on the ID and then verifying the page within each case. While this
works fine, it is very akward to handle two Usages that share a single ID,
such as HID_USAGE_PRESSURE and HID_USAGE_X because the case statement can
only have a single identifier.

To work around this, we now check the full 32-bit HID Usage directly rather
than first checking the ID and then the page.  This allows the switch
statement to have distinct cases for e.g. HID_USAGE_PRESSURE and
HID_USAGE_X.
