Luben Tuikov 025a64a587 drm/amdgpu: I2C EEPROM full memory addressing ... * "eeprom_addr" is now 32-bit wide. * Remove "slave_addr" from the I2C EEPROM driver interface. The I2C EEPROM Device Type Identifier is fixed at 1010b, and the rest of the bits of the Device Address Byte/Device Select Code, are memory address bits, where the first three of those bits are the hardware selection bits. All this is now a 19-bit address and passed as "eeprom_addr". This abstracts the I2C bus for EEPROM devices for this I2C EEPROM driver. Now clients only pass the 19-bit EEPROM memory address, to the I2C EEPROM driver, as the 32-bit "eeprom_addr", from which they want to read from or write to.
