      sc1200: fix ->dma_base equal zero handling · 88ae4d8c
      Bartlomiej Zolnierkiewicz authored
      Set hwif->atapi_dma/{ultra,mwdma}_mask and drive->autodma after checking that
      ->dma_base exists.  If ->dma_base is not set (== PCI BAR4 cannot be reserved)
      then DMA hooks shouldn't be initialized or bad things will happen.
      
      OTOH hwif->set_{pio,dma}_mode hooks should be set even if hwif->dma_base == 0.

      ide: move ide_config_drive_speed() calls to upper layers (take 2) · 88b2b32b
      Bartlomiej Zolnierkiewicz authored
      * Convert {ide_hwif_t,ide_pci_device_t}->host_flag to be u16.
      
      * Add IDE_HFLAG_POST_SET_MODE host flag to indicate the need to program 
        the host for the transfer mode after programming the device.  Set it
        in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac
        and via82cxxx host drivers.
      
      * Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely
        skip programming of host/device for the transfer mode ("smart" hosts).
        Set it in it821x host driver and check it in ide_tune_dma().
      
      * Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all
        direct ->set_pio_mode/->speedproc users to use these helpers.
      
      * Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc
        methods to callers.
      
      * Rename ->speedproc method to ->set_dma_mode, make it void and update
        all implementations accordingly.
      
      * Update ide_set_xfer_rate() comments.
      
      * Unexport ide_config_drive_speed().
      
      v2:
      * Fix issues noticed by Sergei:
        - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt
          to setting DMA modes from sc1200_set_pio_mode() to do_special()
        - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma()
        - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode()
        - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode()
        - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL
        - don't set ->set_{pio,dma}_mode on it821x in "smart" mode
        - fix build problem in pmac.c
        - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c
        - improve patch description
      
      Changes in behavior caused by this patch:
      - HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change
        PIO mode if it821x controller is in "smart" mode
      - removal of two debugging printk-s (from cs5530.c and sc1200.c)
      - transfer modes 0x00-0x07 passed from user space may be programmed twice on
        the device (not really an issue since 0x00 is not supported correctly by
        any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid)

      ide: remove ide_dma_enable() · 4728d546
      Bartlomiej Zolnierkiewicz authored
      * check ->speedproc return value in ide_tune_dma()
      * use ide_tune_dma() in cmd64x/cs5530/sc1200/siimage/sl82c105/scc_pata drivers

      cs5530/sc1200: add ->speedproc support · 3c3f5d2c
      Bartlomiej Zolnierkiewicz authored
      * add {cs5530,sc1200}_tunepio() for programming PIO timings
      
      * 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
      Bartlomiej Zolnierkiewicz authored
      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
      Bartlomiej Zolnierkiewicz authored
      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.

      Bartlomiej Zolnierkiewicz authored
      * add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return
