Hi Steve,

I know you've been using OMAP2_DSS_USE_DSI_PLL Kconfig option to use DSI PLL for pixel clock, so I wanted to point out that that has changed in the current DSS2 master (soon to be merged, I hope). You will now need to select the clock usage in the board file, for example:

arch/arm/mach-omap2/board-overo.c +5 -0
