From 32d858fc4f022c47022a7c871fa1a2f08009eb3d Mon Sep 17 00:00:00 2001 From: Murali Karicheri Date: Thu, 21 Feb 2019 12:02:07 -0500 Subject: [PATCH] ARM: dts: k2g-ice: add dt node for netcp This patch adds dt node for DP83867 phy used on K2G ICE board and also enable netcp device nodes for the board. 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. Unfortunately, the phy data manual disallows this. Add ti,dp83867-rxctrl-strap-quirk in the phy node to allow software to enable workaround suggested for this incorrect strap setting. This ensures proper operation of this PHY. The dts bindings are kept in sync with that from 4.14.y linux kernel. This required the pinmux device related bindings to be commented out to allow for compilation.
