+         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.
