lcd cape and kernel 3.12

We have a custom LCD cape working great with kernel 3.8. I’m hoping I will have better results with sgx on kernel 3.12, so i’d like to start testing it. I ran into compatibility issue with our device tree file. I resolved a few issues, but haven’t gotten it sorted out correctly. It doesn’t appear any other cape’s dts files have been ported as yet.

Does anyone know of any reference material you could point me to that would be useful?
