2011-11-26eeprom_93cx6: Add data direction control.Ben Dooks1-0/+2
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.

2007-10-10ax88796: add 93cx6 eeprom supportMagnus Damm1-1/+2
Hook up the 93cx6 eeprom code to the ax88796 driver and modify the ax88796 driver to read out the mac address from the eeprom. We need this for the ax88796 on certain SuperH boards. The pin configuration used to connect the eeprom to the ax88796 on these boards is the same as pointed out by the ax88796 datasheet, so we can probably reuse this code for multiple platforms in the future.
