[PATCH 2/8] ARM: dts: omap4-droid4: Configure regulators
From: Sebastian Reichel
Date: Wed Mar 01 2017 - 20:09:39 EST
From: Tony Lindgren <tony@xxxxxxxxxxx>
With drivers/mfd/motorola-cpcap.c and drivers/regulator/cpcap-regulator.c
we can now configure proper regulators for droid 4.
Let's add regulator voltages and switch over MMC, eMMC and WLAN to use
the CPCAP regulators.
