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 Changes in v8: - Split out docs changes, rework in RST/Sphinx, and rebase against docs-next - Update for changes to vb2_queue alloc_ctxs - Rebase against git://linuxtv.org/media_tree.git and re-test Changes in v7: - Tested by Andrew Duggan and Chris Healy. - Update bus_info to add "rmi4:" bus. - Fix code style issues in sur40 changes. Changes in v6: - Remove BUF_TYPE_TOUCH_CAPTURE, as discussed with Hans V touch devices will use BUF_TYPE_VIDEO_CAPTURE. - Touch devices should now register CAP_VIDEO_CAPTURE: CAP_TOUCH just says that this is a touch device, not a video device, but otherwise it acts the same. - Add some code to v4l_s_fmt() to set sensible default values for fields not used by touch. - Improve naming/doc of RMI4 F54 report types. - Various minor DocBook fixes, and split to separate patch. - Update my email address. - Rework sur40 changes so that PIX_FMT_GREY is supported for backward compatibility. Florian is it possible for you to test? 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
