Subject: [PATCH 4.9 148/172] ARM: dts: OMAP3: Fix MFG ID EEPROM

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adam Ford <aford173@...il.com>

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")
