1 TI QSPI controller.
4 - compatible : should be "ti,dra7xxx-qspi" or "ti,am4372-qspi".
5 - reg: Should contain QSPI registers location and length.
6 - reg-names: Should contain the resource reg names.
7 	- qspi_base: Qspi configuration register Address space
8 	- qspi_mmap: Memory mapped Address space
9 	- (optional) qspi_ctrlmod: Control module Address space
10 - interrupts: should contain the qspi interrupt number.
11 - #address-cells, #size-cells : Must be present if the device has sub-nodes
12 - ti,hwmods: Name of the hwmod associated to the QSPI
15 - spi-max-frequency: Definition as per
16                      Documentation/devicetree/bindings/spi/spi-bus.txt
19 - syscon-chipselects: Handle to system control region contains QSPI
22 NOTE: TI QSPI controller requires different pinmux and IODelay
23 parameters for Mode-0 and Mode-3 operations, which needs to be set up by
24 the bootloader (U-Boot). Default configuration only supports Mode-0
25 operation. Hence, "spi-cpol" and "spi-cpha" DT properties cannot be
26 specified in the slave nodes of TI QSPI controller without appropriate
