      ide: add struct ide_dma_ops (take 3) · 5e37bdc0
      由 Bartlomiej Zolnierkiewicz 提交于 
      Add struct ide_dma_ops and convert core code + drivers to use it.

While at it:

* Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods.

* Drop "ide_" "infixes" from DMA methods.

* au1xxx-ide.c:
  - use auide_dma_{test_irq,end}() directly in auide_dma_timeout()

* pdc202xx_old.c:
  - drop "old_" "infixes" from DMA methods

* siimage.c:
  - add siimage_dma_test_irq() helper
  - print SATA warning in siimage_init_one()

* Remove no longer needed ->init_hwif implementations.

v2:
* Changes based on review from Sergei:
  - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/
  - s/drive->hwif/hwif/ in idefloppy_pc_intr().
  - fix patch description w.r.t. au1xxx-ide changes
  - fix au1xxx-ide build
  - fix naming for cmd64*_dma_ops
  - drop "ide_" and "old_" infixes
  - s/hpt3xxx_dma_ops/hpt37x_dma_ops/
  - s/hpt370x_dma_ops/hpt370_dma_ops/
  - use correct DMA ops for HPT302/N, HPT371/N and HPT374
  - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/

v3:
* Two bugs slipped in v2 (noticed by Sergei):
  - use correct DMA ops for HPT374 (for real this time)
  - handle HPT370/HPT370A properly

      ide: do complete DMA setup in ->init_dma method (take 2) · b123f56e
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Make ide_hwif_setup_dma() return an error value.

* Pass 'const struct ide_port_info *d' instead of 'unsigned long dmabase'
  to ->init_dma method and make it return an error value.

* Rename ide_get_or_set_dma_base() to ide_pci_dma_base(),
  change ordering of its arguments and then export it.

* Export ide_pci_set_master().

* Do complete DMA setup inside ->init_dma method and update ->init_dma
  users accordingly.

* Sanitize code for DMA setup in ide_init_port().

v2:
* Fix for CONFIG_BLK_DEV_IDEDMA_PCI=n configs
  (from Jiri Slaby <jirislaby@gmail.com>):

  Fix following compiler warning by returning EINVAL:

  In file included from ANYTHING-INCLUDING-IDE.H:45:
  include/linux/ide.h: In function ‘ide_hwif_setup_dma’:
  include/linux/ide.h:1022: warning: no return statement in function returning non-void

      * There is no need to call ide_release_dma_engine().

* Move the code up to (and including) ide_allocate_dma_engine()
  call to the callers of ide_setup_dma().

There should be no functional changes caused by this patch.

      ide: factor out setting PCI bus-mastering from ide_hwif_setup_dma() · d54452fb
      由 Bartlomiej Zolnierkiewicz 提交于 
      Factor out setting PCI bus-mastering from ide_hwif_setup_dma()
to ide_pci_set_master() helper.

While at it:

* don't read PCI Command register if not necessary

* use PCI device name instead of hwif->name

* cleanup ide_hwif_setup_dma() a bit

There should be no functional changes caused by this patch.

      ide: manage resources for PCI devices in ide_pci_enable() (take 3) · 0d1bad21
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Reserve PCI BARs 0-3 (0-1 for single port controllers) in
  ide_pci_enable() and remove ide_hwif_request_regions() call
  from ide_device_add_all() (also cleanup resource management
  in scc_pata host driver).

* Fix handling of PCI BAR 4 in ide_pci_enable(), then cleanup
  ide_iomio_dma() (+ init_hwif_trm290() in trm290 host driver)
  and remove ide_release[_iomio]_dma().

v2:
* Fixup trm290 host driver.

v3:
* Because of scc_pata host driver changes we need to call
  pci_request_selected_regions() also in setup_mmio_scc().

      由 Bartlomiej Zolnierkiewicz 提交于 
      * ide_init_hwif_ports() call in setup-pci.c::ide_hwif_configure()
  doesn't depend on the default cotrol register offset, default IRQ
  or ppc_ide_md.ide_init_hwif implementations so ide_std_init_ports()
  can always be used.

* Since 'base' is always non-zero and thus hwif->io_ports[IDE_DATA_OFFSET]
  is also non-zero always clear hwif->noprobe.

      ide: make remaining built-in only IDE host drivers modular (take 2) · ade2daf9
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c
  file for probing PCI host drivers registered with IDE core (special case
  for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of
  the ordering in which all IDE host drivers are probed when IDE is built-in
  during link time.

* Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch
  specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris
  arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific).

* Move probing of ide-cris (cris arch specific) host driver before cmd640
  (x86 arch specific).

* Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends
  on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300
  (h8300 arch specific).

* Add "probe_vlb" kernel parameter to cmd640 host driver and update
  Documentation/ide.txt accordingly.

* Make IDE_ARM config option visible so it can also be disabled if needed.

* Remove bogus comment from ide.c while at it.

v2:
* Fix two issues spotted by Sergei:
  - replace ENOMEM error value by ENOENT in ide-h8300 host driver
  - fix MODULE_PARM_DESC() in cmd640 host driver

  - pdc202xx_new.c::pdcnew_quirkproc()
  - pdc202xx_old.c::pdc202xx_quirkproc()

* Make ->quirkproc void.

* Move calling ->quirkproc from do_identify() to probe_hwif().

* Convert it821x_fixups() to it821x_quirkproc() in it821x.c.

* Convert siimage_fixup() to sil_quirkproc() in siimage.c, also remove
  no longer needed drive->present check from is_dev_seagate_sata().

* Convert ide_undecoded_slave() to accept 'drive' instead of 'hwif'
  as an argument.  Then convert ide_register_hw() to accept 'quirkproc'
  argument instead of 'fixup' one.

* Remove no longer needed ->fixup method.

      ide: (hopefully) fix VDMA for CS5520 · aea5d375
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Set the correct hwif->dma_base for the second channel in
  ide_get_or_set_dma_base().

* Remove DMA enable code from cs5520_set_pio_mode(), this can
  be handled by the generic ->dma_host_on method now.

* Add VDMA check to ide_config_drive_speed().

* drive->using_dma was never enabled since cs5520 host driver's
  ->ide_dma_on method overrided the generic ->ide_dma_on (so
  __ide_dma_on() was never called, drive->using_dma was never set
  and VDMA was never used since it depends on drive->using_dma).

  Fix it by using ->dma_host_on method instead of ->ide_dma_on
  (also add matching ->dma_host_off method).
