[PATCH 0/2] Model SMPS10 regulator
From: Kishon Vijay Abraham I
Date: Thu Jun 20 2013 - 04:40:18 EST
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.
