This patch series is adding support for second version of Marvell HW
overlay for Cadence xSPI IP block.

masking and full-duplex, variable length SPI operations.
All that functionalites allows xSPI block to operate not only with
memory devices, but also with simple SPI devices, or TPM devices.

  spi: cadence: Add MRVL overlay bindings documentation for Cadence XSPI
  spi: cadence: Add Marvell xSPI IP overlay changes
