From 3b745d0b3dc18cd1e6344c97d61b3b1872c57219 Mon Sep 17 00:00:00 2001 From: Sam Protsenko Date: Thu, 31 Jul 2025 18:45:32 -0500 Subject: [PATCH 01/20] arm64: dts: exynos: Add Ethernet node for E850-96 board The E850-96 board has a hard-wired LAN9514 chip which acts as a USB hub and Ethernet bridge. It's being discovered dynamically when the USB bus gets enumerated, but the corresponding Ethernet device tree node is still needed for the bootloader to pass the MAC address through. Add LAN9514 nodes as described in [1]. 'local-mac-address' property (in the 'ethernet' node) is used for MAC address handover from the bootloader to Linux.

Each protocol can work independently and configured using external configuration inputs. As each USI instance has access to 4 pins, there are multiple possible configurations: - the first 2 and the last 2 pins can be i2c (sda/scl) or uart (rx/tx) - the 4 pins can be used for 4 pin uart or spi For each group of 4 pins, there is one usi instance that can access all 4 pins, and a second usi instance that can be used to set the last 2 pins in i2c mode. Such configuration can be achieved by setting the mode property of usiX and usiX_i2c nodes correctly - if usiX is set to take up 2 pins, then usiX_i2c can be set to take the other 2. If usiX is set for 4 pins, then usiX_i2c should be left disabled. Define all the USI nodes from peric0 (usi4), peric1 (usi7-10), peric2 (usi0-6, usi11) and cmgp (usi0-6_cmgp, 2 pin usi7_cmgp) blocks, as well as their respective uart and i2c subnodes. Suffix labels for blocks in CMGP instances with _cmgpX, and follow the naming conventions from the vendor kernel to avoid confusion. Spi support will be added later on.
