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.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments.

Not sure, if this needs an IB anyway or if the DTS can be pulled by the corresponding SoC subsys and the DT binding can go through another tree in the same cycle. If not, I can certainly split the device tree (to my knowledge, it was said that it should be a complete description :). I'd expect that Lee is picking up the first 6 patches after they got an ACK. Please correct me if I'm wrong, Lee. In any case, I'd give this v1 some time to get some feedback on the patches. -michael
