The enable bit and transform offset of cluster windows should be
cleared when it work at linear mode, or we may have a iommu fault
issue.

I guess same here?
Fixes: 604be85547ce ("drm/rockchip: Add VOP2 driver")
I'm not sure if we need a Fixes tag here, in fact this issue never happens on
rk3566/8 , because the cluster windows of rk356x only support afbc format,
they don't have a chance to switch between afbc and linear mode.
Of course, the lack support of linear mode of rk356x cluster windows is a
thoughtless
of IC design, if it really support both afbc and linear format, we indeed need
this fix.
The situation is the same as patch 03/12.
So I hope follow your advice, if it need a Fixes tag here.
