[PATCH 0/4] spi-synquacer fixes and improvement

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
