From 3fb2ef111d6f799f3da8860c1a90ef3d9c36ea55 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 24 Jun 2016 13:58:09 +0530 Subject: regulator: tps65218: force set power-up/down strobe to 3 for dcdc3 The reset value for this register seems broken on certain versions of tps65218 chip, so make sure the dcdc3 settings is proper. Needed for proper functionality of rtc+ddr / rtc-only modes.
