[PATCH v3 10/15] dsa: Add new optional devicetree property to describe EEPROM size

From: Guenter Roeck
Date: Wed Oct 29 2014 - 13:49:14 EST


The dsa core now supports reading from and writing to a switch EEPROM
if connected. Describe optional devicetree property indicating that
an EEPROM is present and its size.
