-* STMicroelectronics Quad Serial Peripheral Interface(QSPI)
-
-Required properties:
-- compatible: should be "st,stm32f469-qspi"
-- reg: the first contains the register location and length.
-       the second contains the memory mapping address and length
-- reg-names: should contain the reg names "qspi" "qspi_mm"
-- interrupts: should contain the interrupt for the device
-- clocks: the phandle of the clock needed by the QSPI controller
-- A pinctrl must be defined to set pins in mode of operation for QSPI transfer
-
-Optional properties:
-- resets: must contain the phandle to the reset controller.
-
-A spi flash (NOR/NAND) must be a child of spi node and could have some
-properties. Also see jedec,spi-nor.txt.
-
-Required properties:
-- reg: chip-Select number (QSPI controller may connect 2 flashes)
-- spi-max-frequency: max frequency of spi bus
-
-Optional properties:
-- spi-rx-bus-width: see ./spi-bus.txt for the description
-- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
-Documentation/devicetree/bindings/dma/dma.txt.
-- dma-names: DMA request names should include "tx" and "rx" if present.
-
-Example:
-
-qspi: spi@a0001000 {
-	compatible = "st,stm32f469-qspi";
-	reg = <0xa0001000 0x1000>, <0x90000000 0x10000000>;
