[PATCH 0/2] Add support for STM32 SPI

From: Amelie Delaunay
Date: Wed Jun 21 2017 - 10:33:23 EST

This patchset adds support for the STM32 Serial Peripheral Interface (SPI).

It applies to STM32 platforms implementing version 2 of SPI/I2S interface
like STM32H7 series.

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, but here, only master mode is
