This patch series is adding support for second version of Marvell HW overlay for Cadence xSPI IP block. Overlay is HW change made around orginal xSPI block. Overlay extends xSPI features, with clock configuration, interrupt 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.
