Hi Christoph
I guess you can merge this patch from your tree. I hope it is not too
late in this release cycle.
Have a great week!

The timing is perfectly fine, I haven't even started the dma-mapping tree
for v5.13 yet.
Thanks, with all the reviews in I've applied the series to the
dma-mapping tree for 5.13.
This will eventually become a stable baseline branch for the v4l work
and the mips drm driver that needs dma_mmap_pages, but I'd like to wait
a bit for any issues to pop up in linux-next first.
I've applied this to the dma-mapping tree with a more useful commit
log.

When the IOMMU is disabled, the driver still enumerates and initialises
the hardware in order to turn it off. Because IRQ remapping setup is
done early, the irqdomain is set up opportunistically.

This patch dumps all active mapping entries from pagetable
