2017-06-23	spi: stm32: fix error check on mbr being -ve	Colin Ian King	1	-2/+2
	The error check of mbr < 0 is always false because mbr is a u32. Make mbt an int so that a -ve error return from stm32_spi_prepare_mbr can be detected.

2017-06-21	spi: add driver for STM32 SPI controller	Amelie Delaunay	1	-0/+1266
	The STM32 Serial Peripheral Interface (SPI) can be used to communicate with external devices while using the specific synchronous protocol. It supports a half-duplex, full-duplex and simplex synchronous, serial communication with external devices with 4-bit to 16/32-bit per word. It has two 8x/16x 8-bit embedded Rx and TxFIFOs with DMA capability. It can operate in master or slave mode.
