config DM_I2C
bool "Enable Driver Model for I2C drivers"
depends on DM
help
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).
config DM_I2C_COMPAT
bool "Enable I2C compatibility layer"
depends on DM
help
Enable old-style I2C functions for compatibility with existing code.
This option can be enabled as a temporary measure to avoid needing
to convert all code for a board in a single commit. It should not
be enabled for any board in an official release.

Support for Panasonic UniPhier I2C controller driver. This I2C
controller is used on PH1-LD4, PH1-sLD8 or older UniPhier SoCs.

Support for Panasonic UniPhier FIFO-builtin I2C controller driver.
This I2C controller is used on PH1-Pro4 or newer UniPhier SoCs.
