HID: wacom: Fix sensor outbounds and redefine as offsets from each edge
Many of Wacom's display tablets include an "outbound" area where pen digitizing is possible but outside of the display area. To ensure that pen coordinates are mapped to the correct on-screen location, the driver sets the minimum and maximum axis values of X and Y to those coordinates which coincide with the screen edge. These values are simply the hardware minimum/maximum plus/minus the outbound size for a particular edge. When outbound support was added/updated inac414da
,fa77034
, andecd618d
, we decided to have the wacom_features structs store the desired minimum and maximum values directly. In hindsight, this was perhaps not the best choice since it has allowed minor errors to crop up unnoticed. Some tablets have had their coordinates over-corrected (e.g. most of the devices "fixed" inecd618d
were already adjusted inac414da
), while others never had a correction applied (e.g. the ISDv5 325, whose declared maximum the hardware maximum instead of the outbound maximum). A less error-prone method of handling the outbound is to let the driver calculate the correct minimum/maximum values by providing it with both the actual hardware maximums and the size of the outbound on each edge. These values are more easy to verify as correct since the values can be trivially compared against specifications. This patch reverts the declared maximum values to the actual hardware maximums, e.g. as declared prior toac414da
(values for these and other display tablets that were subsuquently introduced have been verified against specs). Per-edge outbound sizes are stored in the wacom_features struct as offset_{left,right,top,bottom} and used in combination with the hardware ranges to calculate effective axis ranges for ABS_X and ABS_Y.
