Hi!
I am currently trying to get the HDMI to work on petalinux to run, after I am done setting the HDMI, a GUI using Qt5.
To do so, I have followed (and tweeked a little bit since it's for a platform running Vivado 2013.4 and Petalinux 2013.10) this tutorial. I have also followed this tutorial successfully. So basically, I can successfully boot the Zedboard from the SD card, run and interact with custom PL. But my problem starts when I start trying to use the HDMI.
I downloaded the hdl-master archive from AnalogDevicesInc, sourced all required blocks and created the FSBL. Then, if I create a petalinux project from there and compile it with the current kernel, it boots but the HDMI does not load.
So I kept following the tutorial and added the custom kernel from AnalogDevicesInc. With a little modification to the config file (commenting out every reference to Mathworks), it compiles but throwes a kernel panic. I tried modifying the device tree, modifying the config file, and now I feel kind of stuck.

So my first question is, should I keep trying to use the AnalogDevicesInc kernel or does the mainline petalinux kernel now contains the driver for the ADV7511? If it does, I guess I should look more into the device tree for the HDMI to be recognize?
If I have to use the AnalogDevicesInc kernel, do you have any recommendation on how to proceed forward?
I am using Vivado 2015.4.2 and Petalinux 2015.4.
Thanks!
Paul
