Hi,
This patch series add DT for the Crystalfontz CFA-10056 and Crystalfontz
CFA-10058.
The first patch simplifies board detection in mach-mxs.c as suggested by Thomas
Petazzoni in his review of the precedent DT additions.
The next two patches are adding the DTs.
The last patches are cleaning up the remaining boards DTs.
Changes in v4
- corrected comment for cfa-10056 and made it cfa-10037 compatible
- reordered patches
Changes in v3
- Cleaned up all the DTs for crystalfontz boards.
Changes in v2:
- took into account the review from Maxime Ripard
Thanks,
Alexandre Belloni (6):
