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 drivers/spi/spi-stm32.c | 116 +++++++++++++++++++--------------------- 1 file changed, 54 insertions(+), 62 deletions(-)
