Subject: [U-Boot-Users] [PATCH] fix DIU for small screens
Date: Fri, 11 Jul 2008 04:58:35 +0200 [thread overview]
Message-ID: <1215745115.1657.52.camel@localhost.localdomain> (raw)
The DIU_DIV register is 8 bit not 5 bit. This prevented large DIV values
so it was not possible to set a slow pixel clock and thus prevented
display on small screens.
