From e365280521029c9366bab038915274ddaa1b7195 Mon Sep 17 00:00:00 2001 From: Nisar Sayed Date: Thu, 21 Sep 2017 02:36:38 +0530 Subject: [PATCH] lan78xx: Use default values loaded from EEPROM/OTP after reset Use default value of auto duplex and auto speed values loaded from EEPROM/OTP after reset. The LAN78xx allows platform configurations to be loaded from EEPROM/OTP. Ex: When external phy is connected, the MAC can be configured to have correct auto speed, auto duplex, auto polarity configured from the EEPROM/OTP.
