Subject: [PATCH 1/4] dt-bindings: net: renesas,etheravb: Add additional clocks
Date:   Mon, 28 Dec 2020 15:31:17 -0600
Message-Id: <20201228213121.2331449-1-aford173@gmail.com>

Precedence: bulk

The AVB driver assumes there is an external clock, but it could
be driven by an external clock.  In order to enable a programmable
clock, it needs to be added to the clocks list and enabled in the
driver.  Since there currently only one clock, there is no
clock-names list either.

Update bindings to add the additional optional clock, and explicitly
name both of them.
