2017-09-12misc: i2c_eeprom: Add compatible for AT24MAC402Wenyou Yang
Add the new compatible "atmel,24mac402" to accommodate AT24MAC402. The AT24MAC402 is a 2K Serial EEPROM and the 2-Kbit memory array is internally organized as 16 pages of 16 bytes of EEPROM each. The 48-bit EUI address in the AT24MAC402 are located in the extended memory block. Signed-off-by: Wenyou Yang <wenyou.yang@microchip.com>
2017-09-12misc: i2c_eeprom: Add compatible for 24AA02E48Wenyou Yang
Add the new compatible "microchip,24aa02e48" to accommodate 24AA02E48, the 24AA02E48 is a 2K I2C Serial EEPROM with pre-programmed globally unique, 48-bit node address, and 8-byte page size. Signed-off-by: Wenyou Yang <wenyou.yang@microchip.com>

2016-07-22i2c_eeprom: Add reading supportmario.six@gdsys.cc
This patch implements the reading functionality for the generic I2C EEPROM driver, which was just a non-functional stub until now. Since the page size will be of importance for the writing support, we add suitable members to the private data structure to keep track of it. Compatibility strings for a range of at24c* chips are added. Signed-off-by: Mario Six <mario.six@gdsys.cc> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>

2014-12-11dm: Add a simple EEPROM driverSimon Glass
There seem to be a few EEPROM drivers around - perhaps we should have a single standard one? This simple driver is used for sandbox testing, but could be pressed into more active service.
