[PATCH v4 08/12] arm64: dts: qcom: pm8550: Enable BCL sensor node
From: Manaf Meethalavalappu Pallikunhi
Date: Mon Oct 05 2026 - 08:35:31 EST
Add Battery Current Limiting (BCL) hardware monitor node for pm8550
PMIC. The BCL monitors battery voltage and current, providing hardware
interrupts when configurable thresholds are violated.
