misc: eeprom: ee1004: convert to i2c_new_dummy_device

2019-07-25T08:06:54Z

Move from i2c_new_dummy() to i2c_new_dummy_device(), so we now get an ERRPTR which we use in error handling. Signed-off-by: Wolfram Sang Link: https://lore.kernel.org/r/20190722172616.3982-2-wsa+renesas@sang-engineering.com Signed-off-by: Greg Kroah-Hartman

eeprom: ee1004: Deal with nack on page selection

2019-05-24T18:42:50Z

Some EE1004 implementations will not properly ack page selection commands. They still set the page correctly, so there is no actual error. Deal with this case gracefully by checking the currently selected page after we receive a nack. If the page is set right then we can continue.

eeprom: New ee1004 driver for DDR4 memory

2018-10-15T18:51:46Z

The EEPROMs which hold the SPD data on DDR4 memory modules are no longer standard AT24C02-compatible EEPROMs. They are 512-byte EEPROMs which use only 1 I2C address for data access. You need to switch between the lower page and the upper page of data by sending commands on the SMBus. Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman
