On a side note, we consider this platform deprecated we should either

It's all about degrees, I think we are fine to support the existing
feature set and commit to keeping that working, but I'm not sure we
should be enabling new features for the platform, in particular when the
patches in question cause us to have to diverge from the upstream for a
particular driver.

I'm afraid to say that even without these 2 patches (#10 and #11) we already diverge from upstream (> 3.19)... They reworked a big part of the code (mostly P2M handling) in this version.
