Hi,

This mostly looks good, with a couple of comments below.

This is slightly odd since you're defining the node just above, you could just
add the regulators right there.

No rk808 node? Or adding that once the driver is sorted out?

I'd recommend doing all of these with &-references instead to avoid having to
revisit this if/when the tree topography changes w.r.t. the 'soc' node. Also,
the gpio-keys should be on the top level.
