From fcf5cc92b015684de7c3f45106013b35f54f2fa1 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 17 Dec 2021 01:37:41 +0100 Subject: drm/ingenic: Add support for the nomodeset kernel parameter According to disable Documentation/admin-guide/kernel-parameters.txt, this parameter can be used to disable kernel modesetting. DRM drivers will not perform display-mode changes or accelerated rendering and only the system framebuffer will be available if it was set-up. But only a few DRM drivers currently check for nomodeset, make this driver to also support the command line parameter.
