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
