Subject: [PATCH] ARM64: zynqmp: Fix i2c node's compatible string
Date: Wed, 21 Dec 2016 21:49:48 -0800 [thread overview]
Message-ID: <1482385788-7187-1-git-send-email-moritz.fischer@ettus.com> (raw)
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
