Subject: [PATCH v1 0/7] Initial Kontron SMARC-sAM67 support

Now that the PMIC support is there, we can finally, upstream the
support for this board. Besides the usual device tree, this
patchset contains the support for the on-board house keeping MCU. It
make extensive reuse of the drivers for the former SMARC-sAL28
board. Besides different hwmon sensors, all the dt binding patches
will just add a board specific compatible (in addition to the old
sl28 compatible) to make any future board specific quirks possible.

I'm aware that there is a patch [1] which moves the sl28cpld MFD
schema to a different directory. Once that patch is merged, I'll
repost this series. But I already want to get some early feedback.
