+Qualcomm Technologies, Inc. GENI Serial Engine QUP Wrapper Controller
+
+Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) wrapper
+is a 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 GENI Serial Engine QUP
+Wrapper controller is modeled as a node with zero or more child nodes each
+representing a serial engine.
+
+Required properties:
+- compatible:		Must be "qcom,geni-se-qup".
+- reg:			Must contain QUP register address and length.
+- clock-names:		Must contain "m-ahb" and "s-ahb".
+- clocks:		AHB clocks needed by the device.
+
+Required properties if child node exists:
+- #address-cells: 	Must be <1> for Serial Engine Address
+- #size-cells: 		Must be <1> for Serial Engine Address Size
+- ranges: 		Must be present
+
+Properties for children:
+
+A GENI based QUP wrapper controller node can contain 0 or more child nodes
+representing serial devices.  These serial devices can be a QCOM UART, I2C
+controller, SPI controller, or some combination of aforementioned devices.
+Please refer below the child node definitions for the supported serial
+interface protocols.
+
+Qualcomm Technologies Inc. GENI Serial Engine based I2C Controller
+
+Required properties:
+- compatible:		Must be "qcom,geni-i2c".
+- reg: 			Must contain QUP register address and length.
+- interrupts: 		Must contain I2C interrupt.
+- clock-names: 		Must contain "se".
+- clocks: 		Serial engine core clock needed by the device.
+- #address-cells:	Must be <1> for I2C device address.
+- #size-cells:		Must be <0> as I2C addresses have no size component.
+
+Optional property:
+- clock-frequency:	Desired I2C bus clock frequency in Hz.
+			When missing default to 400000Hz.
+
+Child nodes should conform to I2C bus binding as described in i2c.txt.
+
+Qualcomm Technologies Inc. GENI Serial Engine based UART Controller
+
+Required properties:
+- compatible:		Must be "qcom,geni-debug-uart".
+- reg: 			Must contain UART register location and length.
+- interrupts: 		Must contain UART core interrupts.
+- clock-names:		Must contain "se".
+- clocks:		Serial engine core clock needed by the device.
+
+Qualcomm Technologies Inc. GENI Serial Engine based SPI Controller
+
+Required properties:
+- compatible:		Must contain "qcom,geni-spi".
+- reg:			Must contain SPI register location and length.
+- interrupts:		Must contain SPI controller interrupts.
+- clock-names:		Must contain "se".
+- clocks:		Serial engine core clock needed by the device.
+- spi-max-frequency:	Specifies maximum SPI clock frequency, units - Hz.
+- #address-cells:	Must be <1> to define a chip select address on
+			the SPI bus.
+- #size-cells:		Must be <0>.
+
+Optional property:
+- qcom,rt:		Indicates if the framework worker thread for this
+			controller device should have real-time priority.
