[PATCH 3/3] power: supply: qcom_smbx: program AICL rerun time
From: Robin Snyders via B4 Relay
Date: Tue Aug 11 2026 - 16:38:05 EST
From: Casey Connolly <casey.connolly@xxxxxxxxxx>
The bootloader-provided automatic input current limit rerun interval is
not a stable software interface. Program a consistent three-second
interval during probe. This is required at least on SMB5 hardware.
