Subject: [PATCH 0/8] spi: stm32: fix and enhancements for spi-stm32

The serie provides a fix for the spi-stm32 driver, allowing to properly
handle 0 byte transfer (and thus being able to run spi-loopback-test).

In addition to that, important enhancements are implemented, among them,
supporting transfer larger that what the IP can setup in one go or
allowing to use the SPI bus without cs_gpio.

Alain Volmat (5):
  spi: stm32: properly handle 0 byte transfer
  spi: stm32: do not mandate cs_gpio
  spi: stm32h7: ensure message are smaller than max size
  spi: stm32: defer probe for reset
  spi: stm32: make spurious and overrun interrupts visible

Amelie Delaunay (2):
  spi: stm32: use bitfield macros
  spi: stm32h7: replace private SPI_1HZ_NS with NSEC_PER_SEC

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