| 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. |

| 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. |

| Enable the i2c bus driver emulation by using the GPIOs. The bus GPIO |
| configuration is given by the device tree. Kernel-style device tree |
| bindings are supported. |
