Subject: [PATCH v3] arm: dts: ZII: update MDIO speed and preamble
Date:   Tue,  7 Jul 2020 18:16:27 -0700
Message-Id: <20200708011627.7427-1-cphealy@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Update MDIO configuration with ZII devices to fully utilize
MDIO endpoint capabilities.  All devices support 12.5MHz clock and
don't require MDIO preable.

v3:
- make "status = okay" the last property
v2:
- Fix subject line to reference ZII:
