[PATCH 09/14] eeprom: at24: platform_data: add serial number flag

From: Bartosz Golaszewski
Date: Sun May 29 2016 - 17:56:38 EST


In preparation for supporting the at24cs EEPROM series add a new flag
to the at24 platform data. When set, it should tell the driver that
the chip has an additional read-only memory area that holds a factory
pre-programmed serial number.
