Merge series "spi: Fixes for FSI-attached controller" from Eddie James <eajames@linux.ibm.com>:

This series implements a number of fixes for the FSI-attached SPI
controller driver.

Changes since v1:
 - Switch to a new compatible string for the restricted version of the
   SPI controller, rather than a new boolean parameter.

Brad Bishop (3):
  spi: fsi: Handle 9 to 15 byte transfers lengths
  spi: fsi: Fix clock running too fast
  spi: fsi: Fix use of the bneq+ sequencer instruction

Eddie James (3):
  dt-bindings: fsi: fsi2spi: Add compatible string for restricted
    version
  spi: fsi: Implement restricted size for certain controllers
  spi: fsi: Check mux status before transfers
