2009-05-17ide: remove hw_regs_t typedefBartlomiej Zolnierkiewicz1-1/+1
Remove hw_regs_t typedef and rename struct hw_regs_s to struct ide_hw. There should be no functional changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-05-17ide: pass number of ports to ide_host_{alloc,add}() (v2)Bartlomiej Zolnierkiewicz1-2/+2
Pass number of ports to ide_host_{alloc,add}() and then update all users accordingly. v2: - drop no longer needed NULL initializers in buddha.c, cmd640.c and gayle.c (noticed by Sergei) There should be no functional changes caused by this patch.

2009-05-17ide: remove chipset field from hw_regs_tBartlomiej Zolnierkiewicz1-2/+1
* Convert host drivers that still use hw_regs_t's chipset field to use the one in struct ide_port_info instead. * Move special handling of ide_pci chipset type from ide_hw_configure() to ide_init_port(). * Remove chipset field from hw_regs_t. While at it: - remove stale comment in delkin_cb.c There should be no functional changes caused by this patch.

2009-03-31ide: merge ide_arm and ide_generic host driversBartlomiej Zolnierkiewicz1-5/+13
There is no need for a separate ide_arm host driver nowadays so merge it into ide_generic one. While at it: - return -EBUSY from ide_generic_init() if I/O resources are busy - scale down ide_generic_check_pci_legacy_iobases() for CONFIG_PCI=n Cc: Russell King <rmk@arm.linux.org.uk> Cc: Alexander Schulz <alex@shark-linux.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-31ide-generic: remove no longer needed sysfs interfaceBartlomiej Zolnierkiewicz1-67/+1
Nowadays we have "ide_generic.probe_mask=" module parameter and ide_platform host driver so sysfs interface for adding IDE interfaces is no longer needed. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-03-27ide-generic: use struct ide_port_infoBartlomiej Zolnierkiewicz1-2/+6
This fixes hwif->channel and drive->dn assignments. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-10-13ide-generic: remove no longer needed ide_probe_legacy()Bartlomiej Zolnierkiewicz1-4/+0
There is now a generic solution [ide_generic_check_pci_legacy_iobases()] so MIPS-specific ide_probe_legacy() is no longer necessary. Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-10-10ide-generic: handle probing of legacy io-ports v5Borislav Petkov1-4/+51
Avoid probing the io-ports in case an IDE PCI controller is present and it uses the legacy iobases. If we still want to enforce the probing, we do ide_generic.probe_mask=0x3f on the kernel command line. The iobase checking code is adapted from drivers/ata/pata_legacy.c after converting hex pci ids into their corresponding macros in <linux/pci_ids.h>. Also, check only BAR0/2 resources since those are guaranteed by the workaround in drivers/pci/probe.c:pci_setup_device().

2008-07-24ide-generic: remove ide_default_{io_base,irq}() inlines (take 3)Bartlomiej Zolnierkiewicz1-3/+29
Replace ide_default_{io_base,irq}() inlines by legacy_{bases,irqs}[]. v2: Add missing zero-ing of hws[] (caught during testing by Borislav Petkov). v3: Fix zero-oing of hws[] for _real_ this time. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-24ide-generic: minor fix for mipsBartlomiej Zolnierkiewicz1-0/+4
Move ide_probe_legacy() call to ide_generic_init() so it fails early if necessary and returns the proper error value (nowadays ide_default_io_base() is used only by ide-generic). Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-23ide: add ide_host_free() helper (take 2)Bartlomiej Zolnierkiewicz1-4/+23
* Add ide_host_free() helper and convert ide_host_remove() to use it. * Fix handling of ide_host_register() failure in ide_host_add(), icside.c, ide-generic.c, falconide.c and sgiioc4.c. While at it: * Fix handling of ide_host_alloc_all() failure in ide-generic.c. * Fix handling of ide_host_alloc() failure in falconide.c (also return the correct error value if no device is found). v2: * falconide build fix.

2008-07-23ide: add ide_host_add() helperBartlomiej Zolnierkiewicz1-7/+4
Add ide_host_add() helper which does ide_host_alloc()+ide_host_register(), then convert ide_setup_pci_device[s](), ide_legacy_device_add() and some host drivers to use it. While at it: * Fix ide_setup_pci_device[s](), ide_arm.c, gayle.c, ide-4drives.c, macide.c, q40ide.c, cmd640.c and cs5520.c to return correct error value. * -ENOENT -> -ENOMEM in rapide.c, ide-h8300.c, ide-generic.c, au1xxx-ide.c and pmac.c * -ENODEV -> -ENOMEM in palm_bk3710.c, ide_platform.c and delkin_cb.c * -1 -> -ENOMEM in ide-pnp.c Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-23ide: add struct ide_host (take 3)Bartlomiej Zolnierkiewicz1-19/+9
* Add struct ide_host which keeps pointers to host's ports. * Add ide_host_alloc[_all]() and ide_host_remove() helpers. * Pass 'struct ide_host *host' instead of 'u8 *idx' to ide_device_add[_all]() and rename it to ide_host_register[_all](). * Convert host drivers and core code to use struct ide_host. * Remove no longer needed ide_find_port(). * Make ide_find_port_slot() static. * Unexport ide_unregister(). v2: * Add missing 'struct ide_host *host' to macide.c. v3: * Fix build problem in pmac.c (s/ide_alloc_host/ide_host_alloc/) (Noticed by Stephen Rothwell).

2008-07-23ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3)Bartlomiej Zolnierkiewicz1-11/+12
* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use it instead of calling ide_init_port_hw() directly. [ However if host has > 1 port we must still set hwif->chipset to hint consecutive ide_find_port() call that the previous slot is occupied. ] * Unexport ide_init_port_hw(). v2: * Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c. (Suggested by Geert Uytterhoeven) * Better patch description. v3: * Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell) There should be no functional changes caused by this patch.

2008-06-15ide-generic: don't probe all legacy ISA IDE ports by defaultBartlomiej Zolnierkiewicz1-1/+8
We can't probe all legacy ISA IDE ports by default as the resources may be occupied by other ISA devices. Add "probe_mask" module parameter and probe only first two ISA IDE ports by default leaving the decision about probing the rest to the user (systems with ISA ide2-6 should be very, very rare).

hwif->chipset need to be set properly or ide-generic driver will break once we make a final step in fixing host drivers' dependence on ide_hwifs[].

It is no longer needed to set hwif->mmio flag to tell IDE layer to not manage resources so cleanup host drivers that used hwif->mmio flag only for this purpose. Ditto for ide_legacy_init_one(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-18ide: remove ide_init_default_irq() macroBartlomiej Zolnierkiewicz1-1/+1
* Use ide_default_irq() instead of ide_init_default_irq() in ide_generic host driver (so the correct IRQ is always set regardless of CONFIG_PCI / CONFIG_BLK_DEV_IDEPCI). * Remove no longer needed ide_init_default_irq() macro. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-18ide: move default IDE ports setup to ide_generic host driverBartlomiej Zolnierkiewicz1-3/+9

The commit 139ddfcab50e5eabcc88341c8743a990ac1be6a2 ("ide: move handling of I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe check vs ide_hwif_request_regions() call (so that we now reserve I/O regions before checking for hwif->noprobe). However ide-generic host driver depended on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots. Fix it by passing only indexes of non-empty slots to ide_device_add_all() from ide_generic_init(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+32
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
