From 61eec998c9399d1cce91c7a2f51a4d0cfbab97bb Mon Sep 17 00:00:00 2001 From: Dang Huynh Date: Mon, 22 Jul 2024 14:07:15 +0700 Subject: [PATCH] drm: panel: boe-bf060y8m-aj0: Enable prepare_prev_first Enable prepare_prev_first flag for BF060Y8M-AJ0 panel so that the previous controller should be prepared first before the prepare for the panel is called. This makes sure that the previous controller, likely to be a DSI host controller should be initialized to LP-11 before the panel is powered up.
