Currently the focus is on the CPU block stuff. I hope to get around to the DSA switch driver eventually but this is a small start that lets me boot a mainline kernel on the board I have. I initialiy started with code from openwrt but have paired it down to just the clocksource driver and devicetree. The first two patches in this series are fixing some complaints from make dtbs_check for some existing realtek dts files. They can be applied on their own if desired.
