Bartlomiej Zolnierkiewicz a06876a766 ide: pci: free PCI BARs on initialization failure
Recent pci_assign_irq() changes uncovered a problem with missing freeing of
PCI BARs on PCI IDE host initialization failure:

  ide0: disabled, no IRQ
  ide0: failed to initialize IDE interface
  ide0: disabling port
  cmd64x 0000:00:02.0: IDE controller (0x1095:0x0646 rev 0x07)
  CMD64x_IDE 0000:00:02.0: BAR 0: can't reserve [io  0x8050-0x8057]
  cmd64x 0000:00:02.0: can't reserve resources
  CMD64x_IDE: probe of 0000:00:02.0 failed with error -16

Fix the problem by adding missing freeing of PCI BARs to
ide_setup_pci_controller() and ide_pci_init_two().

Fixes: 30fdfb929e ("PCI: Add a call to pci_assign_irq() in pci_device_probe()")
Fixes: 0e4c2eeb75 ("alpha/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks")

Bartlomiej Zolnierkiewicz b123f56e04 ide: do complete DMA setup in ->init_dma method (take 2)
* 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

Bartlomiej Zolnierkiewicz 63158d5c21 ide: cleanup ide_setup_dma()
* 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.

Bartlomiej Zolnierkiewicz d54452fbf8 ide: factor out setting PCI bus-mastering from ide_hwif_setup_dma()
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

Bartlomiej Zolnierkiewicz 5e59c23684 ide: remove ->cds field from ide_hwif_t (take 2)
* Use hwif->name instead of cds->name in ide_allocate_dma_engine().

* Use pci_name(dev) instead of cds->name in init_dma_pdc202xx().

* Remove no longer needed ->cds field from ide_hwif_t.

v2:

* scc_pata.c also needs to be updated now (noticed by Stephen Rothwell).

There should be no functional changes caused by this patch.

Bartlomiej Zolnierkiewicz 0d1bad216c ide: manage resources for PCI devices in ide_pci_enable() (take 3)
* 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().

Bartlomiej Zolnierkiewicz fe80b937c9 ide: merge ide_match_hwif() and ide_find_port()
* Change ide_match_hwif() argument from 'u8 bootable' to
  'struct ide_port_info *d'.

* Move ide_match_hwif() to ide-probe.c from setup-pci.c and rename
  it to ide_find_port_slot().  Update some comments while at it.

* ide_find_port() can be now just a wrapper for ide_find_port_slot().
