This set obviously does not apply as it has this dependency. The dependency had
issues, and I just asked it to be rebased on the MT8189 series, which include
the refactoring needed and common to both. Please coordinate, the faster I get
an update for MT8189, the faster these two MT8196 will be picked.

regards,
Nicolas
