Hi William, Thanks for looking at this for me.
I'm using 3.8 for video acceleration and Android. I have not been able to get more recent kernels to fully work with everything I need on BBB. I copied the dts file from the am33x-v3.8 tree into my kernel and was able to build and boot the kernel. Now I'm trying to get the 4D LCD4 cape functioning.
