[PATCH v3 0/5] Add support for the Armada 3700 SPI controller

[romain.perier@free-electrons.com (Romain Perier)]

The Marvell Armada 3700 SoC includes an SPI controller. This controller
supports up to 4 SPI slave devices, with dedicated chip selects, CPIO or
FIFO mode with DMA or CPU transfers and different SPI transfer modes
(Standard single, Dual or Quad).

This set of patches adds a basic support for the CPIO mode, then it
enables the FIFO mode (CPU-side only, DMA not supported yet). It also
adds the required definitions of the spi nodes to the devicetree.
