From fa32c6bc92813a76419d1c306e35394cae5028eb Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 15 Sep 2023 10:53:39 +0200 Subject: drm: renesas: shmobile: Use media bus formats in platform data Replace the custom shmob_drm_interface enumeration values with standard media bus formats. This simplifies driver handling of bus formats and prepares for DT support.
