Subject: [PATCH v5 0/9] Output raw touch data via V4L2
Date: Wed, 22 Jun 2016 23:08:24 +0100 [thread overview]
Message-ID: <1466633313-15339-1-git-send-email-nick.dyer@itdev.co.uk> (raw)
This is a series of patches to add output of raw touch diagnostic data via V4L2
to the Atmel maXTouch and Synaptics RMI4 drivers.
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.
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/v4l-touch-2016-06-22
Changes in v5 (Hans Verkuil review):
- Update v4l2-core:
- Add VFL_TYPE_TOUCH, V4L2_BUF_TYPE_TOUCH_CAPTURE and V4L2_CAP_TOUCH
- Change V4L2_INPUT_TYPE_TOUCH_SENSOR to V4L2_INPUT_TYPE_TOUCH
- Improve DocBook documentation
- Add FMT definitions for touch data
- Note this will need the latest version of the heatmap util
- Synaptics RMI4 driver:
- Remove some less important non full frame report types
- Switch report type names to const char * array
- Move a static array to inside context struct
- Split sur40 changes to a separate commit
Changes in v4:
- Address nits from the input side in atmel_mxt_ts patches (Dmitry Torokhov)
- Add Synaptics RMI4 F54 support patch
Changes in v3:
- Address V4L2 review comments from Hans Verkuil
- Run v4l-compliance and fix all issues - needs minor patch here:
https://github.com/ndyer/v4l-utils/commit/cf50469773f
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
