Subject: [PATCH 2/2] drm/edid: Add alternate clock for SMPTE 4K
Date: Tue, 12 Nov 2019 15:53:07 +0800 [thread overview]
Message-ID: <20191112075307.12574-2-Wayne.Lin@amd.com> (raw)
Message-ID: <20191112075307.CaEEOWGSdaZNgyv9vi2kN5uRjeB2jjMHxSTCM07frqQ@z> (raw)
In-Reply-To: <20191112075307.12574-1-Wayne.Lin@amd.com>
[Why]
In hdmi_mode_alternate_clock(), it adds an exception for VIC 4
mode (4096x2160@24) due to there is no alternate clock defined for
that mode in HDMI1.4b. But HDMI2.0 adds 23.98Hz for that mode.
[How]
Remove the exception
