From mboxrd@z Thu Jan 1 00:00:00 1970 From: niklas.cassel@axis.com (Niklas Cassel) Date: Wed, 21 Feb 2018 09:59:56 +0100 Subject: [PATCH v2 4/8] ARM: dts: artpec: migrate ethernet to stmmac binding In-Reply-To: <20180221090000.18091-1-niklas.cassel@axis.com> References: <20180221090000.18091-1-niklas.cassel@axis.com> Message-ID: <20180221090000.18091-5-niklas.cassel@axis.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
