[PATCH v2] v4l: vsp1: Report device model and rev through media device information

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of hardcoding the media device model and hardware revision to
"VSP1" and 0 respectively, report the actual hardware device model and
IP version number.
