Subject: [PATCH 04/14] drm/amd/display: Extend DMUB HW params to allow DM to specify boot options
Date: Thu, 29 Apr 2021 15:51:56 +0800	[thread overview]
Message-ID: <20210429075206.15974-5-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20210429075206.15974-1-Wayne.Lin@amd.com>

From: Eric Yang <Eric.Yang2@amd.com>

[Why & How]
Add the field to HW params to allow DM dynamically pass down debug and
boot options as needed.
