Subject: [PATCH 0/8] spi: enable the SpacemiT K1 SoC QSPI

This series adds support for the SpacemiT K1 SoC QSPI.  This IP
is generally compatible with the Freescale QSPI driver, requiring
three minor changes to enable it to be supported.  The changes
are:
  - Adding support for optional resets
  - Having the clock *not* be disabled when changing its rate
  - Using a fixed 1K size for flash chips rather than having it
    be related to the AHB buffer size.
