[fedora-arm] Raspberry Pi hardware accelerated media support

Hey folks,

I was just looking up Fedora's hardware support for the Raspberry Pi
platform vs the Raspberry Pi OS, and I noticed in the FAQ that we
indicate that the camera and accelerated media stuff doesn't work in
Fedora[1].

I know that previously this depended on weird blobs and a fork of the
OpenMAX libraries, but it seems today that Raspberry Pi OS' kernel
uses v4l2 for this and has some staging drivers that seem suitable for
upstream[2]. Taking a look at the latest in Linus' tree yields that
most of it isn't staged there yet[3], and searching linux-arm-kernel@
doesn't *seem* to yield any recent patch submission for them[4].

All of this to ask: does anyone know what the plan around this stuff
is and when we might see this in Fedora Linux? Am I missing something
in particular that would make this clearer, like a tracker of some
kind or something?

Thanks in advance and best regards!
