[Linux-fbdev-devel] [REVIEW PATCH 7/9] DSS: Add generic DVI panel

[Tomi V. <tom...@no...>]

For some reason we can't allocate enough mem for 1280x1024x24bpp, even if
there should be enough continuous mem. So 1280x1024 mode defaults to
16bpp for now.

You also need DSI PLL to generate pix clock for 1280x1024.
