Consulting help: IMX.6q EIM sdma with upstream linux kernel

I have a hardware platform based on The IMX6.q , which does data acquisition.

Our in house driver does data collection through an fpga connected to the EIM bus.

I need to adapt the EIM driver to use SDMA with the upstream kernel.

Looking for consulting help with a dma engine and sdma script to replace the existing data interrupt.

Ideally doing it in a way that might at some future time be suitable for upstream.

Please contact me if you have the necessary combination of experience, and availability.
