Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

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.
