[PATCH] ARM64: zynqmp: Fix i2c node's compatible string

[Moritz Fischer]

From: Moritz Fischer <mdf@kernel.org>

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

I was checking this internally and p10 is doing something what p14
doesn't need to do. That's why this should be

compatible = "cdns,i2c-r1p14", "cdns,i2c-r1p10";

The same of course for u-boot where also p14 should be added to the driver.

Thanks,
Michal
