	Do not use the global platform_i2c_transfer() function that can only be implemented by a single driver. Instead, make a `struct device` aware transfer() function the only interface function for I2C controller dri- vers to implement. To not force the slave device drivers to be implemented either above generic I2C or specialized SMBus operations, we support SMBus control- lers in the slave device interface too. We start with four simple slave functions: i2c_readb(), i2c_writeb(), i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec- tive SMBus functions. But we keep aliases because it would be weird to force e.g. an I2C EEPROM driver to call smbus_read_byte().

2017-08-06	sb/intel/*: Use common SMBus functions	Arthur Heymans
	All Intel southbridges implement the same SMBus functions. This patch replaces all these similar and mostly identical implementations with a common file. This also makes i2c block read available to all those southbridges. If the northbridge has to read a lot of SPD bytes sequentially, using this function can reduce the time being spent to read SPD five-fold.
