Yep thanks.

Thanks.

Where does "<9000>" come from in the above comment? It looks like
maxim,ramp-rate-setting sets the slew rate, and regulator-ramp-delay
will as well, but will be ignored if maxim,ramp-delay-setting is set. So
does it ever make sense to have both defined for a regulator? And if
not, should max77620 regulators just use the maxim property and not the
regulator core property?
