Subject: [PATCH 00/18] spi: stm32: various driver enhancements

This serie provides spi-stm32 driver enhancements in various area such as:
  - code simplification
  - race condition fix
  - fixes in case of usage of SPI with DMA
  - suspend/resume fixes
  - issues triggered by spi-loopback-test

Alain Volmat (4):
  spi: stm32-spi: defer probe for reset
  spi: stm32: always perform registers configuration prior to transfer
  spi: stm32: properly handle 0 byte transfer
  spi: stm32h7: ensure message are smaller than max size

Amelie Delaunay (10):
  spi: stm32: use bitfield macros
  spi: stm32h7: replace private SPI_1HZ_NS with NSEC_PER_SEC
  spi: stm32h7: fix irq handler
  spi: stm32h7: rework rx fifo read function
  spi: stm32h7: fix dbg/warn/err conditions in irq handler
  spi: stm32: wait for completion in transfer_one()
  spi: stm32: fix fifo threshold level in case of short transfer
  spi: stm32h7: fix handling of dma transfer completed
  spi: stm32: improve suspend/resume management
  spi: stm32: fix stm32_spi_prepare_mbr in case of odd clk_rate

Antonio Borneo (3):
  spi: stm32h7: remove unused mode fault MODF event handling
  spi: stm32h7: fix race condition at end of transfer
  spi: stm32: move spi disable out of irq handler

Etienne Carriere (1):
  spi: stm32-spi: driver uses reset controller only at init
