Subject: [PATCH 5/5] regulator: axp20x: add support for the AXP323
The X-Powers AXP323 is a very close sibling of the AXP313A. The only
difference seems to be the ability to dual-phase the first two DC/DC
converters.
Place the new AXP323 ID next to the existing AXP313A checks, to let
them share most code.
The only difference is the poly-phase detection code, which gets
extended to check the respective bit in a newly used register.
