The I2C uclass interface: probe, read, 6 write and speed, is implemented with the bus drivers operations, 7 which provide methods for bus setting and data transfer. Each chip 8 device (bus child) info is kept as parent platdata. The interface 9 is defined in include/i2c.h. When i2c bus driver supports the i2c 10 uclass, but the device drivers not, then DM_I2C_COMPAT config can 11 be used as compatibility layer. 12 13config DM_I2C_COMPAT 14 bool "Enable I2C compatibility layer" 15 depends on DM 16 help 17 Enable old-style I2C functions for compatibility with existing code. 18 This option can be enabled as a temporary measure to avoid needing 19 to convert all code for a board in a single commit.
