Subject: [PATCH] ARM: dts: update MDIO speed and preamble for zii devices
Date: Sat, 4 Jul 2020 17:59:30 -0700	[thread overview]
Message-ID: <CAFXsbZoYyw6_zUJvR-aeELfixMTy5gJV37vxK+q4RPs6F8uSgw@mail.gmail.com> (raw)

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