Subject: [PATCH 09/14] net: dsa: Add support for switch EEPROM access
Date: Wed, 22 Oct 2014 21:03:17 -0700 [thread overview]
Message-ID: <1414037002-25528-10-git-send-email-linux@roeck-us.net> (raw)
In-Reply-To: <1414037002-25528-1-git-send-email-linux@roeck-us.net>
On some chips it is possible to access the switch eeprom.
Add infrastructure support for it.
