Will someone pick this up? It is laying around for 6 months now.

This drivers allows a fixed framebuffer memory to be set by an additional IORESOURCE_MEM resource. Thus add an example to the DT documentation. Signed-off-by: Alexander Stein <alexander.stein@systec-electronic.com> --- Actually I stumbled myself over this wondering how can I use this specific feature. In the end I found it myself my coincidence. So it's best to add this as an example for other people maybe not that experienced on device-tree.
