menuconfig I3C
tristate "I3C support"
select I2C
help
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
config I3C_OR_I2C
tristate
default m if I3C=m
default I2C
help
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.
