With this patch this code is disabled by default.

These PMICs are I2C-based, multi-function devices, usually with LEDs, PWMs for backlight, BUCKs and LDOs, ADCs and touchscreen controller (on DA9034). This is the base support for the I2C operations, event registration and handling, sub-devices management.
