Subject: [PATCH 0/2] Model SMPS10 regulator

Palmas has SMPS10 regulator which can generate two voltage level 3.75 and 5V.
This SMPS10 has two outputs OUT1 and OUT2 and having one input IN1.

SMPS10-OUT2 is always connected to SMPS10-IN1 via following logic:
- Through parasitic diode (no sw control)
- In bypass mode (bit  configuration is there to enable/disable Bypass)
- In Boost mode (bit configuration is there to enable/disable Boost mode)

SMPS10-OUT1 is connected to the SMPS10-OUT2 pin through Switch (SW control
for enabling/disabling this switch).

There currently doesn't exist a property to indicate if the regulator
supports bypass mode. So added a property to indicate if the regulator
supports bypass mode. Also modified of_get_regulation_constraints() 
to check for that property and set appropriate constraints.

The second patch models SMPS10 as two regulators, SMPS10-OUT1 and SMPS10-OUT2.

Tested regulator enable of SMPS10-OUT1.
Dint test bypass mode.

  regulator: of: Added a property to indicate bypass mode support
  regulator: palmas: model SMPS10 as two regulators
