The ti-gfx-km will not find the dmac function when building.
Since the prototype has changed file/folder since version higher than 4.1. We need to patch the ocfunc.c file and add

This really is an upstream problem. The Git repository at http://git.ti.com/graphics/omap5-sgx-ddk-linux has newer versions, but the Git history is a bit of a mess, making it difficult to know if the latest master branch still applies to the SoCs ti-sgx-km currently supports.

Someone having access to HW and interested in TI platforms should look into this. Could you submit a patch updating the ti-sgx-km to a newer version?
