As the discussion [1] is progressing very slowly:

Jonathan: do you consider having this series as a temporary solution?

Daniel: do you consider having the fix in [2] as a temporary solution (of
course, with the adjustments suggested by Geert)?

There is also [3] for which a similar approach was proposed. From what I
understood from the discussions on [3], Bjorn is OK with the current solution.

I am taking the responsibility to do the necessary adjustments to all these
drivers once there is a resolution for [1].

Thank you,
Claudiu
