Subject: [PATCH 1/4] platform/x86: int3472: Map the VD55G1 power enable GPIO to "vana"
Date: Thu, 24 Sep 2026 20:18:17 +0300 [thread overview]
Message-ID: <20260924171820.1179823-2-koreev.r@gmail.com> (raw)
In-Reply-To: <20260924171820.1179823-1-koreev.r@gmail.com>
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.
