Subject: [PATCH v2 06/24] dt-bindings: net: dwmac: Add Tx/Rx clock sources
Date: Mon, 8 Feb 2021 16:55:50 +0300 [thread overview]
Message-ID: <20210208135609.7685-7-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20210208135609.7685-1-Sergey.Semin@baikalelectronics.ru>
Generic DW *MAC can be connected to an external Transmit and Receive clock
generators. Add the corresponding clocks description and clock-names to
the generic bindings schema so new DW *MAC-based bindings wouldn't declare
its own names of the same clocks.
