Do you mean to say get rid of the ep107 entirely and replace it with,
for example, a zc702 dts?

I have a follow up patchset which splits off a zynq-7000.dtsi and a
zynq-zc702.dts, and which also fixes the 3 interrupt cell problem.
Would you like for me to pull this into v5, or spin up a separate patch
series?

Thanks,

Josh
