From afed51afadb2f5d43e093c969bdf6535b2ea0ad3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] dt/dtoverlays: imx477: Add parameter to set camera
module rotation
Add a rotation DT overlay parameter to allow specifying the camera
module mounting rotation. Set the default rotation to 180 as the module
is typically mounted upside-down.
