MSM8917 uses the SMPA2 and LDOA3 regulators provided by the PM8937 PMIC
for the VDDCX and VDDMX power domains in voltage level mode,
respectively. These definitions should also work on MSM8937.

Would you mind picking up the RPMPD part of [1] and integrating
QM215 and MSM8917 to use the new bindings?

Please, no. That patch was dropped in favour of [2], which doesn't
include RPMPD indices.
And it's good, since we can introduce logical 'default' ones instead
of the ones proposed in the [1].
I started working at making generic RPMPD indices, but I haven't sent
the patches yet.
So, I think, this patch is fine.
