2 bool "Enable Driver Model for I2C drivers"
5 Enable driver model for I2C. 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.
14 bool "Enable I2C compatibility layer"
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. It should not
20 be enabled for any board in an official release.
23 bool "Enable Driver Model for software emulated I2C bus driver"
24 depends on DM_I2C && DM_GPIO
26 Enable the i2c bus driver emulation by using the GPIOs. The bus GPIO
27 configuration is given by the device tree. Kernel-style device tree
28 bindings are supported.

32 bool "UniPhier I2C driver"
33 depends on ARCH_UNIPHIER && DM_I2C
36 Support for Panasonic UniPhier I2C controller driver. This I2C
37 controller is used on PH1-LD4, PH1-sLD8 or older UniPhier SoCs.
39 config SYS_I2C_UNIPHIER_F
40 bool "UniPhier FIFO-builtin I2C driver"
41 depends on ARCH_UNIPHIER && DM_I2C
44 Support for Panasonic UniPhier FIFO-builtin I2C controller driver.
45 This I2C controller is used on PH1-Pro4 or newer UniPhier SoCs.
