It all started in the pxa device-tree submission here : https://lkml.org/lkml/2016/2/25/965
Last submission was a RFC in here: http://www.gossamer-threads.com/lists/linux/kernel/2446863
It will be maintained in : git fetch https://github.com/rjarzmik/linux.git work/ac97
The driving ideas are still the same, and I put them in [1] for memory. This is the first post RFC submission. In order to make a full demonstration of the framework, wm97xx was converted to an MFD, see [2] for the "why".
As this serie is a complete wm9713 change towards the new AC97 bus, here is the patch organization : - 1/9, 2/9, 3/9 and 5/9: the new AC97 bus, for Mark and Takashi to review - 4/9: wm9713 conversion, this one has ugly #ifdefs, should be reviewed more carefully - 6/9: prerequisite for final 9/9, for Marek and Sebastian to approve => this one is independent and can flow through Sebastian's tree in this next-cycle if accepted - 7/9: prerequisite for final 9/9, for Mark/Dmitry => this one is also independent and can flow in this cycle if accepted - 8/9: prerequisite for final 9/9, for Lee to review => this one has a dependency on 2/9, so it probably can't fit in this next-cycle - 9/9: this last one depends on all the patches before, so it can't fit in this next-cycle
As a sum-up, I'd like to push for review for this -next cycle at least the patches 1, 2, 3, 5, 6 and 9.
Happy review.
