As per my response to you at #3715 (comment)

Mainline 5.9 release includes a significant rework to VCHI which stops vcsm-cma (a dependency of bcm2835-codec and bcm2835-isp) from working.
It's being worked on, and I'll be making sure that everything is supported on 5.9 when done.

Closing as the 5.9 and subsequent branches all have the bcm2835-isp driver now (and have had for a while).
