This series are based on 4.2-rc1 and provide four patches to fix mediatek spi driver.

Change in v3:
1. The follow patches are applied, so remove them from series:

  - spi: medaitek: revise quirks compatibility style
  - spi: mediatek: use BIT() to instead of SPI_CMD_*_OFFSET
2. The patch "spi: mediatek: revise coding style" title is not clear, so split it to four patches.

Change in v2:
1. The patch "spi: mediatek: remove redundant clock in prepare_hardware/unprepare_hardware" 
   is applied, so remove it from series.
2. fix incorrect endian usage to support little-endian and big-endian system.
3. revise quirks style to bool.
4. use BIT() to instead of SPI_CMD_*_OFFSET.
5. revise coding style, such as time name, and variable type.
