[PATCH 1/4] platform/x86: int3472: Map the VD55G1 power enable GPIO to "vana"
From: Ruslan Koreev
Date: Thu Sep 24 2026 - 13:44:54 EST
The Lenovo ThinkPad X1 Carbon Gen 14 has an ST VD55G1 IR camera, ACPI
HID TBE20A1, behind an INT3472 discrete device that provides a power
enable GPIO, a reset GPIO and a privacy LED. The vd55g1 driver names its
analog supply "vana", so map the power enable regulator to that name, as
is already done for the imx471 on the same laptop.
