| 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. |
