From 1fbaa958769458fee565703f3c2077b6e7c26093 Mon Sep 17 00:00:00 2001 From: Murali Karicheri Date: Tue, 26 Jun 2018 10:02:56 -0700 Subject: ARM: dts: keystone-k2g-ice: Enable netcp network driver This patch adds dt bindings to enable netcp network driver on K2G ICE boards. This consists of enabling bindings for NSS qmss, pktdma, 2u ethss, mdio, pinmux and netcp devices as well as DP83867 phy. EVM hardware spec recommends to add 0.25 nsec delay in the tx direction and 2.25 nsec delay in the rx direction for internal delay in the clock path to be on the safer side. The board straps RX_DV/RX_CTRL pin of on board DP83867 phy in mode 1. The phy data manual disallows this. Add ti,dp83867-rxctrl-strap-quirk in the phy node to allow software to enable the workaround suggested for this incorrect strap setting. This ensures proper operation of this PHY.
