Hello, The MSCC MIPS SoC line uses a designware IP for the SPI controller but still requires some special handling to give control of the SPI interface to the IP and also has a specific handling for the chip select. Changes in v3: - Added a patch to export dw_spi_set_cs Changes in v2: - Removed already applied patches - separated DT binding changes from the driver patch Alexandre Belloni (5): spi: dw: export dw_spi_set_cs dt-bindings: spi: snps,dw-apb-ssi: document Microsemi integration spi: dw-mmio: add MSCC Ocelot support mips: dts: mscc: Add spi on Ocelot mips: dts: mscc: enable spi and NOR flash support on ocelot PCB123 .../bindings/spi/snps,dw-apb-ssi.txt | 5 +- arch/mips/boot/dts/mscc/ocelot.dtsi | 11 +++ arch/mips/boot/dts/mscc/ocelot_pcb123.dts | 10 +++ drivers/spi/spi-dw-mmio.c | 90 +++++++++++++++++++ drivers/spi/spi-dw.c | 3 +- drivers/spi/spi-dw.h | 1 + 6 files changed, 117 insertions(+), 3 deletions(-) -- 2.18.0
