Subject: [v8 4/6] drm/panel-simple: Update validation warnings for eDP panel description
Date:   Sat, 26 Jun 2021 22:21:06 +0530
Message-Id: <1624726268-14869-5-git-send-email-rajeevny@codeaurora.org>
In-Reply-To: <1624726268-14869-1-git-send-email-rajeevny@codeaurora.org>
References: <1624726268-14869-1-git-send-email-rajeevny@codeaurora.org>
Precedence: bulk

Do not give a warning for the eDP panels if the "bus_format" is
not specified, since most eDP panels can support more than one
bus formats and this can be auto-detected.
Also, update the check to include bpc=10 for the eDP panel.
