Subject: [PATCH v2 1/2] drm/panel: simple: Add bus format for HannStar HSD070PWW1 LVDS panel
Date: Wed, 12 Aug 2015 12:32:12 +0200	[thread overview]
Message-ID: <1439375533-28718-1-git-send-email-l.stach@pengutronix.de> (raw)

From: Philipp Zabel <p.zabel@pengutronix.de>

The bus format both specifies the bpc and the way the individual bits get
serialized into the 7 LVDS timeslots.

While the is only one standard mapping for 6 bpc and so the driver could
infer the bit mapping from the bpc alone, there are more options for the
8 bpc case which makes specifiying the bus format mandatory.
To keep things consistent across panels and to set a precedent for new
panel additions add the proper bus format.
