From f4cf8710a16c0fe1c98e8265b50ac2826869becf Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Sat, 28 Jan 2023 16:55:31 +0100 Subject: video: ti: am335x: restore driver-model code The commit 82f7b869f5d7a ("video: Drop CONFIG_AM335X_LCD") removed not only the LCD legacy implementation but also the code with driver model support. The patch restores the code with driver model support.
