Subject: [PATCH v3 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.

Changes since v2 [ https://lkml.org/lkml/2014/11/17/669 ]:
 - introduce spi_transfer_is_last() helper instead of using a flag
   in spi_transfer structure
 - rebase DTS patch on arm-soc

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: core: Add spi_transfer_is_last() helper
  spi: meson: Add device tree bindings documentation for SPIFC
  spi: meson: Add support for Amlogic Meson SPIFC
  ARM: dts: meson: add node for SPIFC
