+ * DOC: Hardware description
+ *
+ * GENI based QUP is a highly-flexible and programmable module for supporting
+ * a wide range of serial interfaces like UART, SPI, I2C, I3C, etc. A single
+ * QUP module can provide upto 8 serial interfaces, using its internal
+ * serial engines. The actual configuration is determined by the target
+ * platform configuration. The protocol supported by each interface is
+ * determined by the firmware loaded to the serial engine. Each SE consists
+ * of a DMA Engine and GENI sub modules which enable serial engines to
+ * support FIFO and DMA modes of operation.
