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. Patches 1 to 3 should go through the SPI tree while 4 and 5 should probably got throught the MIPS tree once patch 3 has been reviewed by the DT maintainers. Alexandre Belloni (5): spi: dw: fix possible race condition spi: dw: allow providing own set_cs callback 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 | 86 +++++++++++++++++++ drivers/spi/spi-dw.c | 6 +- drivers/spi/spi-dw.h | 1 + 6 files changed, 116 insertions(+), 3 deletions(-) -- 2.18.0
