Ack

I only could test on those two but I can enable it on all rk3588 devices.

I need to check if the current rockchip iommu driver will work for this
decoder. I remember that the iommu code for AV1 was a bit different, not sure
about this rkvdec.

They can be used independently, yes. I'll add rkvdec1 for rk3588 devices
(rk3588s only has 1 core)

Detlev.
