[PATCH v2 2/3] regulator: arizona: Add regulator specific device tree binding document

From: Charles Keepax
Date: Thu Oct 15 2015 - 10:07:10 EST


Subystem specific bindings for the Arizona devices are being factored
out of the MFD binding document into seperate documents for each
subsystem. This patch adds a binding document that covers the existing
regulator specific bindings.
