Subject: [U-Boot] [PATCH] MIMC200: reduce LCD pixclock
Date: Tue, 11 Aug 2009 11:33:47 +0100	[thread overview]
Message-ID: <4A81490B.2000306@mimc.co.uk> (raw)

[Resent to add CC u-boot at lists.denx.de]

The initial pixclock for the MIMC200 board is wrong (and causes
screen corruption due to DMA underruns).

This patch simply reduces the pixel clock to fix the problem.
