Dear all, My ac100 screen is flickering so much. I realized I'm not using it anymore. So if anyone wants to have it for free would be for me a huge pleasure to give it away. I'm based in milan and I'll be in London for the next week. Maybe someone needs it.

The series is rather long, so I may have missed it, but I think you need
one
more patch to the apbdma binding to document the use of #dma-cells, what value it has, and what the format of the dma specifiers in slave drivers needs to be.
Yes, you're right. I will fold the following into "ARM: tegra: document use of standard DMA DT bindings":
