[PATCH 1/2] arm64: dts: freescale: imx93-phycore-som: Move ethernet0 alias to SoM

[PATCH 1/2] arm64: dts: freescale: imx93-phycore-som: Move ethernet0 alias to SoM

[Primoz Fiser]

Move alias for ethernet0 interface to the phyCORE-i.MX93 SoM include
file. The reason behind it is that the physical location of the PHY chip
connected to FEC interface is on the SoM itself and alias thus belongs
into the SoM device-tree. Consequently, it can be used by all boards
based on the phyCORE-i.MX93 SoM (phyBOARD-Segin and phyBOARD-Nash).

This also enables us to mark FEC interface as the primary / first for
networking in the bootloader and systemd (predictable interface names).

[PATCH 2/2] arm64: dts: freescale: imx93-phyboard-segin: Set ethernet1 alias

[Primoz Fiser]

Set ethernet1 alias to EQOS interface on phyBOARD-Segin-i.MX93 marking
it the secondary networking interface. The primary ethernet0 interface
is already set by the SoM include file (imx93-phycore-som.dtsi).

Applied both, thanks!
