Subject: MIMC200: reduce LCD pixclock
X-Git-Tag: v2009.08-rc3~24^2
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=54e399f110bbaa24e662e6dd9e88ddb86989d668;p=oweals%2Fu-boot.git

MIMC200: reduce LCD pixclock

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.
