From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ley Foon Tan Date: Fri, 4 May 2018 18:49:21 +0800 Subject: [U-Boot] [PATCH v2 3/3] net: designware: Add reset ctrl to driver In-Reply-To: <1525430961-45527-1-git-send-email-ley.foon.tan@intel.com> References: <1525430961-45527-1-git-send-email-ley.foon.tan@intel.com> Message-ID: <1525430961-45527-4-git-send-email-ley.foon.tan@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 Add code to reset all reset signals as in Ethernet DT node. A reset property is an optional feature, so only print out a warning and do not fail if a reset property is not present. If a reset property is discovered, then use it to deassert, thus bringing the IP out of reset.
