  spi: stm32: Don't warn about spurious interrupts (2024-05-29 19:12:09 +0100)

spi: Fixes for v6.10

A series of fixes that came in since the merge window, the main thing
being the fixes Andy did for DMA sync where we were calling into the DMA
API in suprising ways and causing issues as a result, the main thing
being confusing the IOMMU code.

We've also got some fairly important fixes for the stm32 driver, it
supports a wide range of hardware and some optimisations that were done
recently have broken on some systems, and a fix to prevent glitched
signals on the bus in the cadence driver.

----------------------------------------------------------------
Andy Shevchenko (3):
      spi: Don't mark message DMA mapped when no transfer in it is
      spi: Check if transfer is mapped before calling DMA sync APIs
      spi: Assign dummy scatterlist to unidirectional transfers

Mark Brown (1):
      soi: Don't call DMA sync API when not needed

Uwe Kleine-König (2):
      spi: stm32: Revert change that enabled controller before asserting CS
      spi: stm32: Don't warn about spurious interrupts

Witold Sadowski (1):
      spi: cadence: Ensure data lines set to low during dummy-cycle period
