Subject: [PATCH v2 0/8] Input: atmel_mxt_ts - output raw touch diagnostic data via V4L
Date: Wed, 4 May 2016 18:07:10 +0100 [thread overview]
Message-ID: <1462381638-7818-1-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
Changes in v2:
- Split pixfmt changes into separate commit and add DocBook
- Introduce VFL_TYPE_TOUCH_SENSOR and /dev/v4l-touch
- Remove "single node" support for now, it may be better to treat it as metadata later
- Explicitly set VFL_DIR_RX
- Fix Kconfig
