From 0f5bb5b5de3b18877373f746bdb85d8ea0efeedf Mon Sep 17 00:00:00 2001
From: Josh Cartwright <joshc@codeaurora.org>

Subject: [PATCH] regulator: rpm: add support for RPM-controller SMB208
The IPQ8064 reference boards make use of SMB208 regulators which are
controlled by RPM. Implement support for these regulators in the RPM
regulator driver.
