When we support SPI-NAND flash with spi-synquacer driver,
we encounter several issues.
This series fixes the spi-synquacer driver to make SPI-NAND flash
device work. This series also includes some improvement and
simplifies the implementation.

Masahisa Kojima (4):
  spi: synquacer: busy variable must be initialized before use
  spi: synquacer: wait until slave is deselected
  spi: synquacer: DMSTART bit must not be set while transferring
  spi: synquacer: simplify tx completion checking
