[PATCH V2 0/4] ARM: tegra: dalmore: add regulators

[Laxman Dewangan]

This series add the regulators for Dalmore platform.
Dalmore also have the Palma PMIC as primary PMIC but 
dt population will be send later once DT documentation
finalize.

Changes from V1:
- Rearrange patches so that config change will be last patch.
- Correct some sentence and Caps.
- fix compilation issue arise in mid of patches.

[PATCH V2 1/4] ARM: tegra: dalmore: add cpu regulator node

[Laxman Dewangan]

Dalmore uses the TPS51632 as CPU regulator. The device is connected
on I2C5.

Add DT node for TPS51632.

[PATCH V2 2/4] ARM: tegra: dalmore: add TPS65090 node

[Laxman Dewangan]

NVIDIA's Tegra114 reference platform, Dalmore, uses the TPS65090 as
secondary PMICs which is mainly act as voltage switch regulator
controlled by i2c communication.

Add DT node for TPS65090.

[PATCH V2 4/4] ARM: tegra: enable Tegra114 based platform PMICs

[Laxman Dewangan]

NVIDIA's Tegra114 has two reference platforms, Dalmore and Pluto.
Dalmore uses following PMICs:
- TPS65913 as primary PMIC.
- TPS65090 as secondary PMIC used for switch regulators and battery charging.
- TPS51632 for CPU regulator.

Pluto uses only TPS65913.

Enable config variable for these PMICs for Dalomore and Pluto.

The unit-address (i.e. "@43" part) of the node name is typically omitted
if it isn't required to make the node name unique.

The series is applied. The first 3 patches to Tegra's for-3.10/dt
branch, and patch 4 to Tegra's for-3.10/defconfig banch.

In patch 2,

I removed "@48" there, since the unit-address isn't required to make the
node name unique.
