      HID: wacom: Expect 'touch_max' touches if HID_DG_CONTACTCOUNT not present · df707938
      由 Jason Gerecke 提交于 
      When introduced in commit 1b5d514a, the check 'if (hid_data->cc_index >= 0)'
in 'wacom_wac_finger_pre_report' was intended to switch where the driver
got the expected number of contacts from: HID_DG_CONTACTCOUNT if the usage
was present, or 'touch_max' otherwise. Unfortunately, an oversight worthy
of a brown paper bag (specifically, that 'cc_index' could never be negative)
meant that the latter 'else' clause would never be entered.

The patch prior to this one introduced a way for 'cc_index' to be negative,
but only if HID_DG_CONTACTCOUNT is present in some report _other_ than the
one being processed. To ensure the 'else' clause is also entered for devices
which don't have HID_DG_CONTACTCOUNT on _any_ report, we add the additional
constraint that 'cc_report' be non-zero (which is true only if the usage is
present in some report).

      HID: wacom: Tie cached HID_DG_CONTACTCOUNT indices to report ID · 499522c8
      由 Jason Gerecke 提交于 
      The cached indicies 'cc_index' and 'cc_value_index' introduced in 1b5d514a
are only valid for a single report ID. If a touchscreen has multiple
reports with a HID_DG_CONTACTCOUNT usage, its possible that the values
will not be correct for the report we're handling, resulting in an
incorrect value for 'num_expected'. This has been observed with the Cintiq
Companion 2.

To address this, we store the ID of the report those indicies are valid
for in a new  'cc_report' variable. Before using them to get the expected
contact count, we first check if the ID of the report we're processing
matches 'cc_report'. If it doesn't, we update the indicies to point to
the HID_DG_CONTACTCOUNT usage of the current report (if it has one).

      HID: wacom: Report full pressure range for Intuos, Cintiq 13HD Touch · 8d515fda
      由 Jason Gerecke 提交于 
      The new Intuos tablets added in eda01dab and the Cintiq 13HD Touch added
in b4bf2120 are capable of reporting 2048 levels of pressure. Although the
kernel reports the correct range to userspace, an oversight has resulted
in the driver ingoring the 11th pressure bit and only sending pressures
of 0 through 1023.

We could fix this issue by expanding the type check to include these
devices, but it makes much more sense to just have the driver look at
the device's maximum pressure when determining if it should read the
11th bit.

      HID: wacom: Add support for Cintiq Companion 2 · f7acb55c
      由 Jason Gerecke 提交于 
      Adds support for the EMR (pen+pad) and touchscreen devices used by the
Wacom Cintiq Companion 2. This applies both to using the device as a
standalone system, as well as when operating in "Cintiq mode" (where
the EMR/touchscreen are simply exposed as USB devices to the system
its connected to).
