From 7109d817db2e020379d0f245300b8ffe651c5c04 Mon Sep 17 00:00:00 2001 From: Marek Behún Date: Wed, 28 Aug 2019 17:12:43 +0200 Subject: arm64: dts: marvell: add DTS for Turris Mox MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds support for the Turris Mox board from CZ.NIC. Turris Mox is as modular router based on the Armada 3720 SOC (same as EspressoBin). The basic board can be extended by different modules. If those are connected, U-Boot lets the kernel know via device-tree. Since modules can be connected in different order and some modules can be connected multiple times (up to three modules containing 8-port ethernet switch in DSA configuration can be connected) we decided against using device-tree overlays, because it got complicated rather quickly. (For example the SFP module can be connected directly to the CPU, or after a switch module. There are four cases and all would need different SFP overlay. There are two types of switch modules (8-port with pass-through and 4-port with no pass-through). For those we would again need at least 6 more overlays.) We therefore decided to put all the possibly connected devices in one device-tree and disable them by default. When U-Boot finds out which modules are connected, it fixes the loaded device-tree accordingly just before boot. By Rob Herring's suggestion we also made it so that U-Boot completely removes nodes which are disabled after this fixup.
