From b3e49987c5706612ee342c685dea799be596df6a Mon Sep 17 00:00:00 2001 From: Naoto Yamaguchi Date: Sun, 23 Apr 2023 20:25:45 +0900 Subject: Enable drm-lease support at psplash The upstream version of psplash is supporting fb based splash screen. On the other hand, drm lease infrastructure is not support fb. This patch enable drm-lease support at psplash. This work contributed by Hiroyuki Ishii at CES2023 demo development.
