From dd43f5e7684ca5666bc7ec298eb15951ae693fb5 Mon Sep 17 00:00:00 2001 From: Colin Foster Date: Fri, 27 Jan 2023 11:35:56 -0800 Subject: [PATCH] dt-bindings: net: mscc,vsc7514-switch: add dsa binding for the vsc7512 The VSC7511, VSC7512, VSC7513 and VSC7514 all have the ability to be controlled either internally by a memory-mapped CPU, or externally via interfaces like SPI and PCIe. The internal CPU of the VSC7511 and 7512 don't have the resources to run Linux, so must be controlled via these external interfaces in a DSA configuration. Add mscc,vsc7512-switch compatible string to indicate that the chips are being controlled externally in a DSA configuration.
