+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>;

+ pinctrl-1 = <&qup_1_spi_2_sleep>;
+ #address-cells = <1>;
+ #size-cells = <0>;

+- interrupts: Interrupt number used by the controller.
+- clocks: Should contain the core and AHB clock.
