+Subject: [PATCH 2/3] I2C: at24: add kernel interface for reading/writing EEPROM
+Date: Monday 25 August 2008
+From: Kevin Hilman <khilman@deeprootsystems.com>
+To: davinci-linux-open-source@linux.davincidsp.com
+
+This patch adds an interface by which other kernel code can read/write
+detected EEPROM.
+
+The platform code registers a 'setup' callback with the
+at24_platform_data. When the at24 driver detects an EEPROM, it fills
+out the read and write functions of at24_iface and calls the setup
+callback. The platform code can then use the read/write functions in
+the at24_iface struct for reading and writing the EEPROM.
+
+Original idea, review and updates by David Brownell <david-b@pacbell.net>
+
+Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
