Merge series "Compatible string consolidation for NXP DSPI driver" from Vladimir Oltean <olteanv@gmail.com>:

This series makes room in the driver for differentiation between the
controllers which currently operate in TCFQ mode. Most of these are
actually capable of a lot more in terms of throughput. This is in
preparation of a second series which will convert the remaining users of
TCFQ mode altogether to XSPI mode with command cycling.

Vladimir Oltean (6):
  doc: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCs
  spi: spi-fsl-dspi: Use specific compatible strings for all SoC
    instantiations
  spi: spi-fsl-dspi: Parameterize the FIFO size and DMA buffer size
  spi: spi-fsl-dspi: LS2080A and LX2160A support XSPI mode
  spi: spi-fsl-dspi: Support SPI software timestamping in all non-DMA
    modes
  spi: spi-fsl-dspi: Convert the instantiations that support it to DMA
