Subject: [PATCH 01/19] drm/amd/display: update connector->display_info after read edid
Date: Mon, 16 Mar 2020 09:49:02 -0400	[thread overview]
Message-ID: <20200316134920.2526155-2-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20200316134920.2526155-1-Rodrigo.Siqueira@amd.com>

From: Hersen Wu <hersenxs.wu@amd.com>

[Why]
drm_connector->display_info is not passed to amdgpu_dm right way after
read edid.

[How]
display_info is parsed from edid and saved into drm_connector by
drm_connector_update_edid_proerty which is called within
amdgpu_dm_update_connector_after_detect. call this function after read
edid to update drm_connector->display_info
