There is a different kernel that we (Analog Device's) maintains, which includes 
both ALSA drivers
for the audio chip (ADAU1761) and the HDMI output (ADV7511).

https://github.com/analogdevicesinc/linux

there are a few zynq branches in there. Normally Xilinx pulls drivers from 
there for their kernels, 
but anyone can do the same.

Our build instructions (if that's the sort of thing you want to do) is at:
http://wiki.analog.com/resources/eval/user-guides/ad-fmcomms2-ebz/software/linux/zynq_2014r2

We provide binaries for Zed which includes a 3.17 kernel and Xbuntu/xfce for 
many of
the FMC prototyping cards we make.
http://wiki.analog.com/resources/tools-software/linux-software/zynq_images

This does include GNURadio (3.7.4) binary, which some people used/contributed.
This doesn't support the GNURadio FPGA accelerator work that was done. (if that 
is
what you were really looking for).

Upstream - it's hard to upstream the device side, when Xilinx hasn't upstream 
the DMA side.
Greg (and others) do not like half a driver. Things are getting better now, and 
we need to
focus on that more.
