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.

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.
