+QTI [Qualcomm Technologies Inc] Quad Serial Peripheral Interface (QSPI)
+
+QSPI [Quad Serial Peripheral Interface] allows single dual and quad read/write
+access to slaves. QTI's QSPI controller implements the QSPI protocol to
interface
+with slaves like NOR Flash devices.
+
+Required properties:
+- compatible: Should contain:
+ "qcom,qspi-v1"
+- reg: Contains the base register location and length
+- interrupts: Interrupt number used by the controller.
+- clocks: Contains the core and AHB clock names.
+- clock-names: "core" for core clock and "iface" for AHB clock.
+- spi-max-frequency: Maximum SPI core clock frequency in Hz.
+
+SPI slave nodes must be children of the SPI master node and can contain
+properties described in Documentation/devicetree/bindings/spi/spi-bus.txt
+
+Example:
+
+ qspi: qspi@7418000 {
+ compatible = "qcom,qspi-v1";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x7418000 0x600>;
+ interrupts = <0 459 0>;
+ clock-names = "iface", "core";
+ clocks = <&clock_gcc clk_gcc_qspi_ahb_clk>,
+ <&clock_gcc clk_gcc_qspi_ser_clk>;
+
+ device@0 {
+ compatible = "dummy_device";
+ reg = <x>; /* CS for the device */
+ spi-max-frequency = <f>; /* Max supported frequency of
the slave (Hz) */
+ };
+ };
