I would like to merge as soon as they can becase most of them
Some fixes, However the patch 2/7 has a dependency on an iommu
Patch and if it is no merged first the compilation will be broken.
So maybe they can be marged as soon as iommu patches are merged.

That looks like double work, having the revert now to merge after. If
Someone needs tidspbridge withouts those patche, they can go back to
A previous commit. The issues will be fixed as soon as the dependencies
Are merged.
