This series adds support for SPI on STM32F7 processors. The STM32F7 SPI
peripheral is nearly identical to the STM32F4, with the only significant
differences being that it supports a wider range of word sizes, and the
addition of 32-bit transmit and receive FIFOs.
Ben Wolsieffer (5):
spi: stm32: rename stm32f4_* to stm32fx_*
spi: stm32: use callbacks for read_rx and write_tx
dt-bindings: spi: add stm32f7-spi compatible
spi: stm32: add STM32F7 support
ARM: dts: stm32: add SPI support on STM32F746
