From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alison Wang Date: Fri, 19 Feb 2016 15:52:28 +0800 Subject: [U-Boot] [PATCH] net: phy: atheros: Fix problem with phy_reset() clearing BMCR Message-ID: <1455868348-3088-1-git-send-email-b18965@freescale.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de In commit [net: phy: do not read configuration register on reset], phy_reset() will clear the BMCR register. Bit 12(AUTO_NEGOTIATION) is cleared too. It causes auto-negotiation timeout error on Atheros's PHY AR8033. To fix this problem, genphy_config_aneg() and genphy_restart_aneg() needs to be called in ar8035_config() to enable and restart auto-negotiation.
