Subject: [PATCH 0/8] Input: atmel_mxt_ts - output raw touch diagnostic data via V4L
Date: Thu, 21 Apr 2016 10:31:33 +0100	[thread overview]
Message-ID: <1461231101-1237-1-git-send-email-nick.dyer@itdev.co.uk> (raw)

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:
	https://github.com/ndyer/heatmap/commits/heatmap-v4l

These patches are also available from
	https://github.com/ndyer/linux/commits/diagnostic-v4l

Any feedback appreciated.
