Subject: media: atomisp: csi2-bridge: Add DMI quirk for t4ka3 on Xiaomi Mipad2 Author: Hans de Goede <hdego...@redhat.com> Date: Mon Sep 2 11:52:27 2024 +0200 The t4ka3 sensor on the Xiaomi Mipad2 is used as a back facing sensor, it uses 4 CSI lanes, but the _DSM has CsiLanes set to 2. Extend the existing Xiaomi Mipad2 DMI quirk to override the wrong _DSM setting.
