The patch titled
s3c2410fb: adds pixclock to s3c2410fb_display
has been removed from the -mm tree. Its filename was
s3c2410fb-adds-pixclock-to-s3c2410fb_display.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: s3c2410fb: adds pixclock to s3c2410fb_display
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch adds pixelclock field to the s3c2410fb_display structure and make
use of it in the driver.
The Bast machine defined 9 modes but pixclock and margin values are defined
only for the 640x480 modes so I removed other modes.
This patch also fixes wrong display type constant for the SMDK2440 board.
