4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Kozlowski <krzk@xxxxxxxxxx>
commit 56b5d4ea778c1b0989c5cdb5406d4a488144c416 upstream.
LDO35 uses 25 mV step, not 50 mV. Bucks 7 and 8 use 12.5 mV step
instead of 6.25 mV. Wrong step caused over-voltage (LDO35) or
under-voltage (buck7 and 8) if regulators were used (e.g. on Exynos5420
Arndale Octa board).
