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 .../devicetree/bindings/spi/spi-meson.txt | 22 + arch/arm/boot/dts/meson.dtsi | 9 + drivers/spi/Kconfig | 7 + drivers/spi/Makefile | 1 + drivers/spi/spi-meson-spifc.c | 462 +++++++++++++++++++++ include/linux/spi/spi.h | 6 + 6 files changed, 507 insertions(+) create mode 100644 Documentation/devicetree/bindings/spi/spi-meson.txt create mode 100644 drivers/spi/spi-meson-spifc.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
