+Qualcomm Universal Peripheral (QUP) Serial Peripheral Interface (SPI)
+
+The QUP core is an AHB slave that provides a common data path (an output FIFO
+and an input FIFO) for serial peripheral interface (SPI) mini-core.
+
+SPI in master mode supports up to 50MHz, up to four chip selects, programmable
+data path from 4 bits to 32 bits and numerous protocol variants.
+
+Required properties:
+- compatible:     Should contain:
+		  "qcom,spi-qup-v1.1.1" for 8660, 8960 and 8064.
+		  "qcom,spi-qup-v2.1.1" for 8974 and later
+		  "qcom,spi-qup-v2.2.1" for 8974 v2 and later.
+
+- reg:            Should contain base register location and length
+- interrupts:     Interrupt number used by this controller
+
+- clocks:         Should contain the core clock and the AHB clock.
+- clock-names:    Should be "core" for the core clock and "iface" for the
+                  AHB clock.
+
+- #address-cells: Number of cells required to define a chip select
+                  address on the SPI bus. Should be set to 1.
+- #size-cells:    Should be zero.
+
+Optional properties:
+- spi-max-frequency: Specifies maximum SPI clock frequency,
+                     Units - Hz. Definition as per
+                     Documentation/devicetree/bindings/spi/spi-bus.txt
+- num-cs:	total number of chipselects
+- cs-gpios:	should specify GPIOs used for chipselects.
+		The gpios will be referred to as reg = <index> in the SPI child
+		nodes.  If unspecified, a single SPI device without a chip
+		select can be used.
+
+
+SPI slave nodes must be children of the SPI master node and can contain
+properties described in Documentation/devicetree/bindings/spi/spi-bus.txt
