[PATCH 0/5] Add support for MSCC Ocelot SPI

[Alexandre Belloni <alexandre.belloni@xxxxxxxxxxx>]

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
