From b49de2dfcf207e763a3b1fe63630a22183706842 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Wed, 21 Feb 2018 09:59:56 +0100 Subject: [PATCH] ARM: dts: artpec: migrate ethernet to stmmac binding The snps,dwc-qos-ethernet binding is still supported as a glue layer in the stmmac driver. However, since the snps,dwc-qos-ethernet binding is now deprecated, migrate to stmmac's native binding. At the same time, enable features supported by the stmmac driver, such as PTP, LPI, and an additional tx queue.
