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/mctp/Kconfig"
config I3CDEV
tristate "I3C device interface"
depends on I3C
help
Say Y here to use i3c-* device files, usually found in the /dev
directory on your system. They make it possible to have user-space
programs use the I3C devices.
This support is also available as a module. If so, the module
will be called i3cdev.
Note that this application programming interface is EXPERIMENTAL
and hence SUBJECT TO CHANGE WITHOUT NOTICE while it stabilizes.
config I3C_HUB
tristate "I3C HUB support"
depends on I3C
select REGMAP_I3C
help
This enables support for I3C HUB. Say Y here to use I3C HUB driver to
configure I3C HUB device.
I3C HUB drivers will be loaded automatically when I3C device with BCR
equals to 0xC2 (HUB device) is detected on the bus.
