From 74685b08fbb26ff5b8448fabe0941a53269dd33e Mon Sep 17 00:00:00 2001 From: Alex Date: Tue, 6 Dec 2016 10:56:51 -0800 Subject: [PATCH] drivers: net: cpsw-phy-sel: Clear RGMII_IDMODE on "rgmii" links Support for setting the RGMII_IDMODE bit was added in the commit referenced below. However, that commit did not add the symmetrical clearing of the bit by way of setting it in "mask". Add it here. Note that the documentation marks clearing this bit as "reserved", however, according to TI, support for delaying the clock does exist in the MAC, although it is not officially supported. We tested this on a board with an RGMII to RGMII link that will not work unless this bit is cleared.
