Input: synaptics-rmi4 - fill initial format
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.
