Above works with this series in U-Boot and also in mainline linux. Not sure the RK3588 bifurcation part of driver have been verified on real HW, rk3588 boards available for testing have typicality not used bifurcation.
Upstream kernel bifurcation code looks ok to me. It's quite different from Rockchip vendor implementation, which might have confused Kever. I also missed this when having a quick look initially. As you said Rock 5A, Rock 5B and EVB1 do not use bifurcation, so no testing happened on our side.
my Bananapi R2Pro (rk3568) uses bifurcation and it is working in mainline Linux, but not yet in uboot.
posted my test-results here: https://patchwork.ozlabs.org/project/uboot/patch/20230918173624.31464-1-linu...
