Qualcomm Technologies, Inc's PMIC has battery current limiting peripheral,
|
|
which can monitor for high battery current and low battery voltage in the
|
|
hardware. The BCL peripheral driver interacts with the PMIC peripheral using
|
|
the SPMI driver interface. The hardware can take threshold for notifying for
|
|
high battery current or low battery voltage events. This driver works only
|
|
with PMIC version 5, where the same BCL peripheral can be found in multiple
|
|
PMIC's that are used in a device, with limited functionalities. For example,
|
|
one PMIC can have only vbat monitoring, while the other PMIC can have both
|
|
vbat and ibat monitoring. This is a common driver, that can interact
|
|
with the multiple BCL peripherals.

and Rsense input.
