sorry, took a bit longer to find time for a test-run.
Except the missing EXPORT_SYMBOL already pointed out in patch1,
my displays are still working on modern (with iommu) and the older
(without iommu) Rockchip socs, so
On rk3188, rk3288, rk3328 and rk3399
Tested-by: Heiko Stuebner <heiko@sntech.de>
and in general
