Benjamin Tissoires 3cb83157e8 Input: Revert "wacom - testing result shows get_report is unnecessary."
This reverts commit 1b2faaf7e2.

The Intuos4 series presents a bug in which it hangs if it receives
a set feature command while switching to the enhanced mode.
This bug is triggered when plugging an Intuos 4 while having
a gnome user session up and running.

Jason Gerecke d51ddb2bf6 Input: wacom - add support for three new ISDv4 sensors
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).

Jason Gerecke e9fc413f4a Input: wacom - override 'pressure_max' with value from HID_USAGE_PRESSURE
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.

Jason Gerecke 5866d9e3b7 Input: wacom - use full 32-bit HID Usage value in switch statement
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.

Issue is not seen a lot because 1) it doesn't need to retry for
a lot of tablets and 2) a lot of failures that need a retry are
from an -ETIMEDOUT and hopefully buffer is not touched in this case.

At least one user has shown logs with buffer being modified during

Jason Gerecke aea2bf6a57 Input: wacom - handle split-sensor devices with internal hubs
Like our other pen-and-touch products, the Cintiq 24HD touch needs data
to be shared between its two sensors to facilitate proximity-based palm
rejection.

Unlike other tablets that report sensor data through separate interfaces
of the same USB device, the Cintiq 24HD touch has separate USB devices
that are connected to an internal USB hub.

This patch makes it possible to designate the USB VID/PID of the other
device so that the two may share data.  To ensure we don't accidentally
link to a sensor from a physically separate device (if several have been
plugged in), we limit the search to siblings (i.e., devices directly
connected to the same hub).

Jason Gerecke 115d5e12a7 Input: wacom - introduce wacom_fix_phy_from_hid
The Cintiq 24HD touch cannot use wacom_set_phy_from_res to determine
the physical size of the touch sensor since the pen and touch are
on separate USB devices. The physical size is, however, provided in
the HID descriptor, just scaled to a unit we don't use.

This patch introduces the function wacom_fix_phy_from_hid to let
us make use of the unit and exponent data provided by HID to set
the [xy]_phy variables to an appropriate value. This function
relies on a trimmed-down version of hidinput_calc_abs_res from
the hid-input.c.

gone away.  This patch removes it from being used in the
driver and uses dev_err() instead.

Jason Gerecke ae584ca473 Input: wacom - add Intuos5 multitouch sensor support
Intuos5 tablets with PTH-* model numbers include a multitouch sensor
which use the same touch reports as the 3rd-generation Bamboo. No
useful information is in the HID descriptor for the touch interface
so hardcoded values are used during setup.

Jason Gerecke 9b5b95dd51 Input: wacom - add Intuos5 Touch Ring LED support
The Touch Ring LEDs on Intuos5 tablets use a different report
format which supports only 4 levels of brightness. We remap
the 7-bit value obtained from sysfs to an appropriate value
for the tablet. Control of the crop mark LEDs (new to the I5)
is left for a later patch.
