Subject: [PATCH 0/3] spi: OCTAL mode fixes

From: Patrice Chotard <patrice.chotard@...s.st.com>

During tests performed using spidev_test in OCTAL mode with spi-stm32-qspi.c,
several issues has been found :
  _ OCTAL mode wasn't supported in spi.c
  _ CCR register wasn't set correctly when OCTAL mode is set in spi-stm32-qspi.c.
  _ Fix dual flash mode sanity test in spi-stm32-qspi.c

Patrice Chotard (3):
  spi: stm32: qspi: Fix dual flash mode sanity test in
    stm32_qspi_setup()
  spi: stm32: qspi: Clamp stm32_qspi_get_mode() output to CCR_BUSWIDTH_4
  spi: add OCTAL mode support
