Subject: [PATCH v3] arm64: dts: zii-ultra: update MDIO speed and preamble
Date: Tue,  7 Jul 2020 18:00:05 -0700	[thread overview]
Message-ID: <20200708010005.6366-1-cphealy@gmail.com> (raw)

Update MDIO configuration with zii-ultra device to fully utilize
MDIO endpoint capabilities.  Device supports 12.5MHz clock and
doesn't require MDIO preamble.

Signed-off-by: Chris Healy <cphealy@gmail.com>

v3:
- make "status = okay" the last property
v2:
- Fix subject line to reference zii-ultra:
- Get rid of "=<1>;" from suppress-preamble lines
