- Enable driver model for I2C. This SPI flash interface
- (spi_flash_probe(), spi_flash_write(), etc.) is then
- implemented by the SPI flash uclass. There is one standard
- SPI flash driver which knows how to probe most chips
- supported by U-Boot. The uclass interface is defined in
- include/spi_flash.h, but is currently fully compatible
- with the old interface to avoid confusion and duplication
- during the transition parent. SPI and SPI flash must be
- enabled together (it is not possible to use driver model
- for one and not the other).
+ Enable driver model for I2C. The I2C uclass interface: probe, read,
+ write and speed, is implemented with the bus drivers operations,
+ which provide methods for bus setting and data transfer. Each chip
+ device (bus child) info is kept as parent platdata. The interface
+ is defined in include/i2c.h. When i2c bus driver supports the i2c
+ uclass, but the device drivers not, then DM_I2C_COMPAT config can
+ be used as compatibility layer.
