From d4860025a3fd9c20a801c2273227906874e76413 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 7 May 2025 20:47:36 +0200 Subject: [PATCH] platform/x86: int3472: For mt9m114 sensors map powerdown to powerenable MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit mt9m114 atomisp designs declare both reset and powerdown pins in their GPIO type DSM, but the mt9m114 only has a reset pin. The powerdown pin seems to control the regulators suppyling power to the sensor and the privacy LED. Add a mapping of powerdown to powerenable for the mt9m114 for this. While at is also add a comment to document the ov7251 mapping.
