A few comments, mainly about your documentation on the Variscite
website.  Specifically the schematics.  Please tell your hardware
people to be consistent in your naming conventions for pins.

MPP_GPIO/PM_GPIO appear to be interchangeable.  And it's usually
best to split out the PMIC pins from the non-pmic.  That's my 2
cents at least.

Schematics show this to be a Home button.  If so this needs to be
updated to reflect that.

qcom isnt making this board.  Please use something like "variscite,dart",
"qcom,apq8016"

Can you try removing the echi and using the chipidea instead.  Take a
look at the current db410c in -next.  Try it out and see if that works
for you.  If it does, modify your nodes to match up.

Same here, I think some things changed here.  Need to update.
switch-gpio went away.
