Subject: [PATCH] drm/panel: add rotation support for Elida KD35T133 panels
Date: Fri, 2 Apr 2021 15:48:47 -0500 [thread overview]
Message-ID: <SN6PR06MB534253E1CFDEA6917230F57BA57A9@SN6PR06MB5342.namprd06.prod.outlook.com> (raw)
Update the panel to allow setting the rotation value in device tree.
Tested on an Odroid Go Advance, where the panel is by default rotated 270
degrees.
