From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chee Tien Fong Date: Tue, 10 Jan 2017 13:20:30 +0800 Subject: [U-Boot] [PATCH v4 17/28] arm: socfpga: arria10: update dwmac reset function to support Arria10 In-Reply-To: <1484025641-5412-1-git-send-email-tien.fong.chee@intel.com> References: <1484025641-5412-1-git-send-email-tien.fong.chee@intel.com> Message-ID: <1484025641-5412-18-git-send-email-tien.fong.chee@intel.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Tien Fong Chee On the Arria10, the EMAC phy mode configuration for each EMACs is located in separate registers versus being in 1 register for the GEN5 devices. The Arria10 also has 3 EMACs compared to 2 for the GEN5 devices. Update the dwmac_deassert_reset function to support both GEN5 and Arria10 devices.
