13 Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) wrapper
14 is a programmable module for supporting a wide range of serial interfaces
15 like UART, SPI, I2C, I3C, etc. A single QUP module can provide upto 8 Serial
16 Interfaces, using its internal Serial Engines. The GENI Serial Engine QUP
17 Wrapper controller is modeled as a node with zero or more child nodes each
18 representing a serial engine.
