Hi, all!
I have question about media subsystem. I can't configure my device.
My system based on NXP I.MX6QP cpu. I use latest stable kernel from
kernel.org. This time kernel version 5.5.11. Also I connect to I.MX MIPI
cameras from Raspberry Pi (Rev 2.1 with Sony IMX219). For IMX219 used
actual driver from [1]. Userspace based on Gentoo Linux, have
media-utils version 1.2.1, v4l2-utils version 1.18.0, gstreamer version
1.14.5 with v4l2 plugins. Also Wayland version 1.17 based graphics with
XWayland.
Camera written in DTB:
