From 0a888f584c48984cb9657a5d42dc994b33c264a7 Mon Sep 17 00:00:00 2001 From: Mugunthan V N Date: Mon, 22 Jun 2015 14:43:10 +0530 Subject: [PATCH] ARM: DRA72x: fix io delay calibration for ethernet we currently use in-development IODelay values for DRA72x which are proposed in the data sheet, however, DRA72x EVM uses DP83865 ethernet Phy over RGMII. The PHY characteristics and routing choices made on the EVM, make the current iodelay values fail ethernet communication. Instead, we need to choose custom values for DRA72x-evm specifically designed for the PHY and routing on the platform for ethernet to function.
