      ide: add ide_set{_max}_pio() (take 4) · 26bcb879
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags
  and set them in ht6560, cmd640, cmd64x and sc1200 host drivers.

* Add set_pio_mode_abuse() for checking if host driver has a non-standard
  ->tuneproc() implementation and use it in do_special().

* Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find
  the maximum PIO mode supported by the host), also add ide_set_max_pio()
  wrapper for ide_set_pio() to use for auto-tuning.  Convert users of
  ->tuneproc to use ide_set{_max}_pio() where possible.  This leaves only
  do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as
  a direct users of ->tuneproc.

* Remove no longer needed ide_get_best_pio_mode() calls and printk-s
  reporting PIO mode selected from ->tuneproc implementations.

* Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const.

* Remove stale comment from ide_config_drive_speed().

v2:
* Fix "ata_" prefix (Noticed by Jeff).

v3:
* Minor cleanups/fixups per Sergei's suggestions.

v4:
* Fix compile problem in drivers/ide/pci/cmd640.c
  (Noticed by Andrew Morton).

* Improve some ->set_pio_mode comments.

      ide: move ide_rate_filter() calls to the upper layer (take 2) · f212ff28
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Move ide_rate_filter() calls from host drivers to IDE core.

* Make ide_rate_filter() static.

* Make 'speed' argument of ->speedproc const.

v2:
* Fix it8213_tune_chipset() comment.

There should be no functionality changes caused by this patch.

* add {cs5530,sc1200}_tune_chipset() (->speedproc method) for setting
  transfer mode and convert {cs5530,sc1200}_config_dma() to use it

      cs5530/sc1200: DMA support cleanup · a01ba401
      由 Bartlomiej Zolnierkiewicz 提交于 
      sc1200.c:

* remove open-coded variant of ide_dma_host_off() (== ->dma_host_off),
  it is not needed because ->dma_off_quietly calls ->dma_host_off

* use ->dma_host_on (== ide_dma_host_on() for this driver) instead of
  open-coded variant, call it from the users of sc1200_config_dma2()

  [ there is no need to call ->dma_host_on in sc1200_config_dma() because
    core code takes care of calling ->ide_dma_on on successful execution
    of ->ide_dma_check ]

* add comment about ->tuneproc interface abuse

cs5530.c/sc1200.c:

* core code takes care of calling ->dma_off_quietly before calling
  ->ide_dma_check so there is no need to call it in ->ide_dma_check methods

* bump driver version

      cs5530/sc1200: add ->udma_filter methods · 5fd216bb
      由 Bartlomiej Zolnierkiewicz 提交于 
      CS5530/SC1200 specifies that two drives on the same cable cannot mix
UDMA/MDMA.  Add {cs5530,sc1200}_udma_filter() to handle this.  This also
makes it possible to remove open-coded best DMA mode selection and use
standard ide_use_dma()/ide_max_dma_mode() helpers.  While at it bump
version numbers.

There should be no functionality changes caused by this patch.
