+description:
+ I3C in master mode supports up to 12.5MHz, SDR mode data transfer in mixed
+ bus mode (I2C and I3C target devices on same i3c bus). It also supports
+ hotjoin, IBI mechanism.

Hot-join
IBI (In-Band Interrupt)

+
+ I3C Controller nodes must be child of GENI based Qualcomm Universal

"nodes must be children" ?

+ Peripharal. Please refer GENI based QUP wrapper controller node bindings
+ described in Documentation/devicetree/bindings/soc/qcom/qcom,geni-se.yaml.
