We should strip the "bcl-" prefix, since these interrupts happen
to be under the bcl device
Ack

Is that something that we expect to change between boards, or is
that an electrical characteristic of the PM7250B?
Yes,  It can change based on battery used for that board as these thresholds will be close below battery OCP spec.
It is not based on pmic spec. Max current threshold support for specific pmic bcl is taken care in driver pmic data.


Thanks,
