From mboxrd@z Thu Jan 1 00:00:00 1970 From: david.wu@rock-chips.com (David Wu) Date: Wed, 9 Aug 2017 20:13:19 +0800 Subject: [PATCH v4 10/12] ARM: dts: rk3228-evb: Enable the internal phy for gmac In-Reply-To: <1502280475-736-1-git-send-email-david.wu@rock-chips.com> References: <1502280475-736-1-git-send-email-david.wu@rock-chips.com> Message-ID: <1502280799-2514-1-git-send-email-david.wu@rock-chips.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch enables the internal phy for rk3228 evb board by default. To use the external 1000M phy on evb board, need to make some switch of evb board to be on.
