2008-10-10ide: add proper PCI PM support (v2)Bartlomiej Zolnierkiewicz
* Keep pointer to ->init_chipset method also in struct ide_host and set it in ide_host_alloc_all(). * Add ide_pci_suspend() and ide_pci_resume() helpers (default ->suspend and ->resume implementations). * ->init_chipset can no longer be marked __devinit. * Add proper PCI PM support to IDE PCI host drivers (rz1000.c and tc86c001.c are skipped for now since they need to be converted from using ->init_hwif to use ->init_chipset instead). v2: * Cleanup CONFIG_PM #ifdef-s per akpm's suggestion.

2008-10-10ide: use ata_id_is_cfa()Bartlomiej Zolnierkiewicz
Use ata_id_is_cfa() in do_identify() instead of open-coding check for CompactFlash devices (the inline helper also takes care of detecting CFs advertising themselves as ATA disks). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-10-10ide: remove SECTOR_WORDS defineBartlomiej Zolnierkiewicz
Just use SECTOR_SIZE instead. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-10-10ide: /proc/ide/hd*/settings reworkBartlomiej Zolnierkiewicz
* Add struct ide_devset, S_* flags, *DEVSET() & ide*_devset_*() macros. * Add 'const struct ide_devset **settings' to ide_driver_t. * Use 'const struct ide_devset **settings' in ide_drive_t instead of 'struct ide_settings_s *settings'. Then convert core code and device drivers to use struct ide_devset and co.: - device settings are no longer allocated dynamically for each device but instead there is an unique struct ide_devset instance per setting - device driver keeps the pointer to the table of pointers to its settings in ide_driver_t.settings - generic settings are kept in ide_generic_setting[] - ide_proc_[un]register_driver(), ide_find_setting_by_name(), ide_{read,write}_setting() and proc_ide_{read,write}_settings() are updated accordingly - ide*_add_settings() are removed * Remove no longer used __ide_add_setting(), ide_add_setting(), __ide_remove_setting() and auto_remove_settings(). * Remove no longer used TYPE_*, SETTING_*, ide_procset_t and ide_settings_t. * ->keep_settings, ->using_dma, ->unmask, ->noflush, ->dsc_overlap, ->nice1, ->addressing, ->wcache and ->nowerr ide_drive_t fields can now be bitfield flags. While at it: * Rename ide_find_setting_by_name() to ide_find_setting(). * Rename write_wcache() to set_wcache(). There should be no functional changes caused by this patch.

2008-10-10ide: remove CONFIG_IDEDISK_MULTI_MODEBartlomiej Zolnierkiewicz
Use multi PIO by default when available and remove no longer needed CONFIG_IDEDISK_MULTI_MODE (it should be safe nowadays, despite to what help entry has been saying). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-10-10ide: remove IDE_CHIPSET_* macrosBartlomiej Zolnierkiewicz

2008-10-10ide: remove no longer needed BUG_ON()-s from init_irq()Bartlomiej Zolnierkiewicz
init_irq() is now called only during initial host registration so these BUG_ON()-s are no loner needed (+ the last one was done too late anyway). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-10-10ide: enhance ide_busy_sleep()Bartlomiej Zolnierkiewicz
* Make ide_busy_sleep() take timeout value as a parameter and also allow use of AltStatus Register if requested with altstatus parameter. Update existing users accordingly. * Convert ide_driveid_update() and actual_try_to_identify() to use ide_busy_sleep(). There should be no functional changes caused by this patch.

2008-10-10ide: fix EXABYTENEST handling in probe_for_drive()Bartlomiej Zolnierkiewicz

2008-10-10ide: remove drive->driveidBartlomiej Zolnierkiewicz
* Factor out HDIO_[OBSOLETE,GET]_IDENTITY ioctls handling to ide_get_identity_ioctl(). * Use temporary buffer in ide_get_identity_ioctl() instead of accessing drive->id directly. * Add ide_id_to_hd_driveid() inline to convert raw id into struct hd_driveid format (needed on big-endian). * Use ide_id_to_hd_driveid() in ide_get_identity_ioctl(), cleanup ide_fix_driveid() and switch ide to use use raw id. * Remove no longer needed drive->driveid. This leaves us with 3 users of struct hd_driveid in tree: - arch/um/drivers/ubd_kern.c - drivers/block/xsysace.c - drivers/usb/storage/isd200.c While at it: * Use ata_id_u{32,64}() and ata_id_has_{dma,lba,iordy}() macros.

2008-10-10ide: make drive->id an union (take 2)Bartlomiej Zolnierkiewicz
Make drive->id an unnamed union so id can be accessed either by using 'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing drive->id users accordingly (using 'u16 *id' when possible). This is an intermediate step to make ide 'struct hd_driveid'-free. While at it: - Add missing KERN_CONTs in it821x.c. - Use ATA_ID_WORDS and ATA_ID_*_LEN defines. - Remove unnecessary checks for drive->id. - s/drive_table/table/ in ide_in_drive_list(). - Cleanup ide_config_drive_speed() a bit. - s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave(). v2: Fix typo in drivers/ide/ppc/pmac.c.

2008-07-24ide: fix for EATA SCSI HBA in ATA emulating modeBartlomiej Zolnierkiewicz
IDE probing code used to skip devices attached to EATA SCSI HBA in ATA emulating mode but because of warm-plug support port I/O resources are no longer freed if no devices are detected on a port and the decision about the driver to use is left up to the user.
