+GENI based Qualcomm Universal Peripheral (QUP) Serial Peripheral Interface (SPI)
+
+The QUP v3 core is a GENI based 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:		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.
+- #address-cells:	Must be <1> to define a chip select address on
+			the SPI bus.
+- #size-cells:		Must be <0>.
+
+SPI Controller nodes must be child of GENI based Qualcomm Universal
+Peripharal. Please refer GENI based QUP wrapper controller node bindings
+described in Documentation/devicetree/bindings/soc/qcom/qcom,geni-se.txt.
+
+SPI slave nodes must be children of the SPI master node and conform to SPI bus
+binding as described in Documentation/devicetree/bindings/spi/spi-bus.txt.
+
+Example:
+	spi0: spi@a84000 {
+		compatible = "qcom,geni-spi";
+		reg = <0xa84000 0x4000>;
+		interrupts = <GIC_SPI 354 IRQ_TYPE_LEVEL_HIGH>;
+		clock-names = "se";
+		clocks = <&clock_gcc GCC_QUPV3_WRAP0_S0_CLK>;
+		pinctrl-names = "default", "sleep";
+		pinctrl-0 = <&qup_1_spi_2_active>;
+		pinctrl-1 = <&qup_1_spi_2_sleep>;
+		#address-cells = <1>;
+		#size-cells = <0>;
