+description: |
+ The BCL OFF cooling device, will be used to disable PMIC bcl.
+ This cooling device will be called when modem RF calibration
+ is performed using external power supply.
+
+ When external power supply is used for RF calibration, ibat current
+ can cross the battery specs and can trigger batfet issues. So pmic bcl
+ should be disabled as it is for protection for battery not external
+ power supply.
