Hello,
This patchset has restructure spi cs_timing, as we know spi core has
removed spi_set_cs_timing() API, it is a correct decision because it
asked spi devices to call it in one more time.
so we need find another way to support user set cs_timing. Actually,
spi_device set spi_delay for cs_timing is enough, and about how to
set cs_timing, just put it one the master driver.
We have test this patch in mediatek platform, it can compeletly meets
our needs.

Mason Zhang (3):
  spi: move cs spi_delay to spi_device
  spi: modify set_cs_timing parameter
  spi: mediatek: modify set_cs_timing callback
