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-2016-06-17
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
