From b30f8bdcfa7dd05f4268348f3388ff903132f28e Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 21 Nov 2011 08:57:56 +0000 Subject: eeprom_93cx6: Add data direction control. Some devices need to know if the data is to be output or read, so add a data direction into the eeprom structure to tell the driver whether the data line should be driven. The user in this case is the Micrel KS8851 which has a direction control for the EEPROM data line and thus needs to know whether to drive it (writing) or to tristate it for receiving.
