This is a series of patches to add diagnostic data support to the Atmel
maXTouch driver. It's a rewrite of the previous implementation which output via
debugfs: it now uses a V4L2 device in a similar way to the sur40 driver.

There are significant performance advantages to putting this code into the
driver. The algorithm for retrieving the data has been fairly consistent across
a range of chips, with the exception of the mXT1386 series (see patch).

We have a utility which can read the data and display it in a useful format:

These patches are also available from

Any feedback appreciated.
