Subject: [PATCH V3 09/14] ARM: dts: stm32: Add alternate pinmux for ethernet
 RGMII
In-Reply-To: <20200331175136.205020-1-marex@denx.de>
References: <20200331175136.205020-1-marex@denx.de>
Message-ID: <20200331175136.205020-10-marex@denx.de>

Add another mux option for DWMAC RGMII, this is used on AV96 board.
