Subject: [PATCH v2 1/4] platform/x86: int3472: Map the VD55G1 power enable GPIO to "vana"
Date: Tue, 29 Sep 2026 12:26:58 +0300 [thread overview]
Message-ID: <20260929092700.1776966-3-koreev.r@gmail.com> (raw)
In-Reply-To: <20260929092700.1776966-1-koreev.r@gmail.com>
The ST VD55G1 IR camera of the Lenovo ThinkPad X1 Carbon Gen 14 (ACPI
HID TBE20A1) gets its analog supply from the power enable GPIO of an
INT3472 discrete device. Map that GPIO to "vana", the supply name the
vd55g1 driver uses, as is already done for the imx471 on the same
laptop.
