Subject: [PATCH 04/17] OMAPDSS: Remove passive matrix LCD support (part 4)
Date: Tue, 26 Jun 2012 09:48:41 +0000	[thread overview]
Message-ID: <1340703414-1915-6-git-send-email-archit@ti.com> (raw)
In-Reply-To: <1340703414-1915-1-git-send-email-archit@ti.com>

Remove configuration of Ac-bias pins

Ac-bias pins need to be configured only for passive matrix displays. Remove
acbi and acb fields in omap_dss_device and their configuration in panel
drivers. Don't program these fields in DISP_POL_FREQo register any more.

The panel driver for sharp-ls037v7dw01, and the panel config for
Innolux AT070TN8 in generic dpi panel driver set acb to a non zero value. This
is most likely carried over from the old omapfb driver which supported passive
matrix displays.
