Subject: [PATCH V2 1/4] dt-bindings: net: renesas,etheravb: Add additional clocks
Date: Fri, 15 Jan 2021 14:19:48 -0600 [thread overview]
Message-ID: <20210115201953.443710-1-aford173@gmail.com> (raw)
The AVB driver assumes there is an external crystal, but it could
be clocked by other means. 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.
