You should consider to create your compatible string just for your board
and record it.

Look at:
arm: dts: zynq: Add Digilent Zybo Z7 board
patch.

Also make sense to record vendor prefix and use it as part of compatible
string.

run it with make W=1 dtbs

And this should be memory@0

Do you really wants to have 3 leds doing heartbeat?

This is not the part of binding and I think it is useless anyway.

IIRC this is EMIO it means wire over programmable logic.
In past we agreed that only PS will be described that's why this
shouldn't be here.

PL related fclk-enable - shouldn't be here.
