Subject: [PATCH RFC 05/12] net: designware: eqos: pass physical device to DMA API
Date: Tue, 21 Feb 2023 09:05:17 +0100 [thread overview]
Message-ID: <20230221080524.607241-6-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230221080524.607241-1-a.fatoum@pengutronix.de>
The Ethernet interface device is just a child of the physical device with
no DT node assigned. As such, it lacks all DMA settings that may be
set in the DT. Fix this by using the hardware device instead.
