[PATCH v2 1/3] adp5061: New driver for ADP5061 I2C battery charger

2018-04-10 Thread Stefan Popa 
This patch adds basic support for Analog Devices I2C programmable linear
battery charger.

With this driver, some parameters can be read and configured such as:
* trickle charge current level
* trickle charge voltage threshold
* weak charge threshold
* constant current
* constant charge voltage limit
* battery full
* input current limit
* charger status
* battery status
* termination current
