Subject: ARM: dts: OMAP3: Fix MFG ID EEPROM

From: Adam Ford <[email protected]>

commit 06e1a5cc570703796ff1bd3a712e8e3b15c6bb0d upstream.

The manufacturing information is stored in the EEPROM. This chip is an AT24C64 not not (nor has it ever been) 24C02. This patch will correctly address the EEPROM to read the entire contents and not just 256 bytes (of 0xff).

Fixes 5e3447a29a38 ("ARM: dts: LogicPD Torpedo: Add AT24 EEPROM Support")
