[PATCH v3 0/4] spi: Add support for Amlogic Meson SPIFC

From: Beniamino Galvani
Date: Sat Nov 22 2014 - 10:24:24 EST


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
