[PATCH 0/3] Fixes for SPI-NAND issues on LS1088A

This patchset resolves issues seen when using SPI-NAND
with the LS1088A's qspi controller.

The main issue seen is data corruption when reading SPI-NAND,
due to a controller quirk not being applied. Using the same
settings as the LS2088A (the bigger brother of LS1088A) solves
this issue.

In the course of debugging the above issue, it was found
that the fsl_qspi driver was not correctly reporting the operation
width (single/dual/quad) configured for the device in DTS.
(e.g I configured my device for single-lane reads only
but quad operations were being issued)

A fix for this issue is already present in Linux and can be
adapted for U-Boot, providing a missing export for
spi_mem_default_supports_op is added.

Mathew McBride (3):
  mem: spi-mem: define spi_mem_default_supports_op
  spi: fsl_qspi: Ensure width is respected in spi-mem operations
  spi: fsl_qspi: apply the same settings for LS1088 as LS208x
