I3C is a serial protocol standardized by the MIPI alliance.
|
|
|
|
It's supposed to be backward compatible with I2C while providing
|
|
support for high speed transfers and native interrupt support
|
|
without the need for extra pins.
|
|
|
|
The I3C protocol also standardizes the slave device types and is
|
|
mainly designed to communicate with sensors.
|
|
|
|
If you want I3C support, you should say Y here and also to the
|
|
specific driver for your bus adapter(s) below.
|
|
|
|
This I3C support can also be built as a module. If so, the module
|
|
will be called i3c.
|
|
|
|
if I3C
|
|
source "drivers/i3c/master/Kconfig"
|
|
endif # I3C
|
|

|

|
|
Device drivers using module_i3c_i2c_driver() can use either
|
|
i2c or i3c hosts, but cannot be built-in for the kernel when
|
|
CONFIG_I3C=m.
|
|
|
|
Add 'depends on I2C_OR_I3C' in Kconfig for those drivers to
|
|
get the correct dependencies.
