mainlining shenanigans
The driver doesn't set an initial video format until s_input is called: $ v4l2-ctl -d /dev/v4l-touch0 --get-input Video input : 0 (Normalized 16-Bit Image: ok) $ v4l2-ctl -d /dev/v4l-touch0 --get-fmt-video Width/Height : 0/0 Pixel Format : '' [...] $ v4l2-ctl -d /dev/v4l-touch0 --set-input 0 Video input set to 0 (Normalized 16-Bit Image: Touch, ok) $ v4l2-ctl -d /dev/v4l-touch0 --get-fmt-video Width/Height : 71/40 Pixel Format : 'TD16' [...] To fix this, initialize the video format to input 0 during probe.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
