rk-6.1-rkr1: captured video from IMX415 at MIPI/CSI not connected to ISP block, on rk3588s platform #164

On my rock 5a I can capture video from my IMX415 camera connected to the 4 lane CSI port if I capture data from /dev/video11. But trying to get data from /dev/video[01] (mainpath/selfpath) doesn't work. The reason seems to be related to the fact that device node /dev/v4l-subdev4 (rkcif-mipi-lvds2) is not created at boot. There seems to be no connection from rkcif to rkisp. All this worked in 5.10 but doesn't work in 6.1. I suspect it is an issue for all rk3588s platforms.
