[PATCH 3/4] ARM: tegra: dalmore: add dt node for TPS65090's regulators

From: Laxman Dewangan
Date: Wed Mar 20 2013 - 09:48:11 EST


NVIDIA's Tegra114 platform, Dalmore, uses the TPS65090 as
secondary PMICs which mainly act as voltage switch controlled
by I2C communication.

Add regulator node for this device.
