The Zynq Ultrascale MP uses version 1.4 of the Cadence IP core which fixes some silicon bugs that needed software workarounds in Version 1.0 that was used on Zynq systems.

Hi Michal,

I think this is a slip up and should be r1p14 for Ultrascale ZynqMP. drivers/i2c/i2c-cadence.c already uses this. I Cc'd the u-boot list, because the same change would be required there.

Cheers,

Moritz
