The ft5x06 is unreliable in sending touch up events, so some touch IDs can become stuck in the detected state. Ensure that IDs that are unreported by the controller are released. Signed-off-by: Dave Stevenson <[email protected]>
Whilst all the datasheets describe FT5x06 as supporting "up to 10 points of absolution X and Y coordinates", the driver implementation for the compatible string "edt,edt-ft5x06" only allows for 5. Switch to the "edt,edt-ft5506" compatible string which allows for 10 points with no other differences. Signed-off-by: Dave Stevenson <[email protected]>
