From a06997f4f59a36e1a539a1d8c475452163c083d5 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 11 Feb 2023 23:38:00 +0100 Subject: [PATCH] arm64: dts: imx8mp: Add FEC RMII pin mux on i.MX8MP DHCOM The i.MX8MP DHCOM SoM may come with either external RGMII PHY or LAN8740Ai RMII PHY on the SoM attached to FEC MAC. Add pin mux settings for both options, so that DT overlay can override these settings on SoM variant with the LAN8740Ai PHY.
