From 3695e4ccfdd3baa29a0d64e4ed08ff1f0d602d09 Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Mon, 27 Apr 2020 15:21:13 +0300 Subject: [PATCH] arm: dts: lx2160aqds: add MDIO slots The LX2160A processor has two external MDIO interfaces, described in the DTS as emdio1 and emdio2. On the LX2160AQDS board EMDIO1 is used with two onboard RGMII PHYs (Realtek RTL8211FD-CG), as well as eight input/output connectors for mezzanine cards. Configuration signals from the Qixis FPGA control the routing of the external MDIOs. Register 0x54 of the Qixis FPGA controls the routing of the EMDIO1 one of the 8 IO slots. As a consequence, a new node is added to describe register 0x54 as a MDIO mux controlled with child nodes describing all the IO slots as MDIO buses. Also, DPMAC 17 and 18 are updated to reference the on-board PHYs.
