Subject: [PATCH v2 0/4] spi: Add support for Amlogic Meson SPIFC

Hi,

this patchset adds a driver for the SPIFC (SPI flash controller)
available in Amlogic Meson6 and Meson8 SoCs. The driver has been
tested on a Meson8 based device to communicate with a Macronix
mx25l1606e serial flash.

The first patch adds a field to the spi_transfer structure that allows
the driver to know in transfer_one() whether the transfer is the last
one and change CS accordingly, without the need to reimplement
transfer_one_message().

Changes since v1 [ https://lkml.org/lkml/2014/11/9/35 ]:
 - decrease busy wait timeout
 - remove check on xfer->speed_hz value in meson_spifc_transfer_one()
 - implement transfer_one() instead of transfer_one_message()
 - remove useless memset of devdata
 - use fixed regmap config
 - implement PM operations
 - don't set master->bus_num
 - allow modular build of the driver

Beniamino Galvani (4):
  spi: Add 'last' flag to spi_transfer structure
  spi: meson: Add device tree bindings documentation for SPIFC
  spi: meson: Add support for Amlogic Meson SPIFC
  ARM: dts: meson: add node for SPIFC
