ide_use_dma() duplicates a lot of ide_max_dma_mode() functionality and as all users of ide_use_dma() were converted to use ide_tune_dma() now it is possible to add missing checks to ide_tune_dma() and remove ide_use_dma() completely, so do it. There should be no functionality changes caused by this patch. Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Add the speedproc() method for setting transfer modes, modify config_for_dma() to call it and use ide_max_dma_mode() to select the best DMA mode. Add support for the multiword DMA modes 0 and 1, using the upper half of the 'drive_data' field to store the DMA timings to program into the drive control register when DMA is turned on for real.

* remove code enabling IORDY and prefetch from config_chipset_for_dma(), as the comment states it has no real effect because these settings are overriden when the PIO mode is set (and for this driver ->autotune == 1 so PIO mode is always programmed) * use ide_tune_dma() in pdcnew_config_drive_xfer_rate() and remove no longer needed config_chipset_for_dma() There should be no functionality changes caused by this patch.

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt to program PIO5 by config_art_rwp_pio() could result in incorrect PIO timings being programmed and possibly the data corruption (for < ATA100 family chipsets PIO0 timings were used, for ATA100 and ATA100a - the random content of test1 variable was used, for ATA133 - MWDMA0 timings were used) * BUG() in sis5513_tune_chipset() if somebody tries to force unsupported PIO5, also cleanup this function a bit while at it * add comment about PIO0 timings for < ATA100 family chipsets * remove open-coded best PIO mode selection from config_art_rwp_pio(), it contained numerous bugs: - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy before using them - it tried to found out maximum PIO mode basing on minimum IORDY cycle time (moreover wrong cycle times were used for PIO1/5) - it was overriding PIO blacklist and conservative PIO "downgrade" done by ide_get_best_pio_mode() * use sis5513_tune_drive() instead of config_art_rwp_pio() in sis5513_config_xfer_rate() so the correct PIO mode is also set on drive even if the device is not IORDY/DMA capable * config_art_rwp_pio() was always setting the best possible mode and not the wanted one - fix it and move ide_get_best_pio_mode() call to config_chipset_for_pio() * don't use ide_find_best_mode() in config_chipset_for_pio(), it was being overriden by config_art_rwp_pio() for the host timings anyway + we need to set the same PIO mode on the device and the host * pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call in sis5513_config_xfer_rate() so the best PIO mode is set on the drive and not PIO4 * rename sis5513_tune_drive() to sis5513_tuneproc() and config_chipset_for_pio() to sis5513_tune_driver() * bump driver version Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt to program PIO5 by svwks_tune_chipset() could result in incorrect PIO timings being programmed and possibly the data corruption (it seems that the minimum possible values were used but I lack the datasheets to be sure) * select best PIO mode in svwks_tune_drive() and not in svwks_tune_chipset() when doing PIO autotuning (pio == 255) * don't try to tune PIO in config_chipset_for_dma() as ide_dma_enable() could return 1 if DMA was previously enabled (svwks_config_drive_xfer_rate() takes care of PIO tuning if no suitable DMA mode is found) * remove config_chipset_for_pio() and use svwks_tune_drive() instead, config_chipset_for_pio() contained numerous bugs when selecting PIO mode (luckily it was only used for devices limited to PIO by capabilities/BIOS): - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy before using them - it tried to found out maximum PIO mode basing on minimum IORDY cycle time (moreover wrong cycle times were used for PIO0/1/5) - it was overriding PIO blacklist and conservative PIO "downgrade" done by ide_get_best_pio_mode() - if the max drive PIO was PIO5 then XFER_PIO_0/XFER_PIO_SLOW was selected (XFER_PIO_SLOW is not supported by svwks_tune_chipset() so the result was the same as if using XFER_PIO_5 => wrong PIO timings were set) - it was overriding drive->current_speed * bump driver version Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

This patch is based on the documentation (I would like to thank Promise for it) and also partially on the older vendor driver. Rewrite mode programming code: * disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled even if both devices on the channel are not DMA capable and after reset * enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset() as they need to be setup correctly also for PIO only devices, plus IORDY wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for ATAPI devices * remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma() (driver sets ->autotune to 1 so PIO modes are always programmed => lower nibble of register A never equals 4 => "chipset_is_set" is always true) * enable PIO mode programming for all ATAPI devices (it was limited to ->media == ide_cdrom devices) * remove extra reads of registers A/B/C, don't read register D et all * do clearing / programming of registers A/B/C in one go (gets rid of extra PCI config space read/write cycle) * set initial values of drive_conf/AP/BP/CP variables to zero (paranoia for the case when PCI reads fail) * remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen (ide_rate_filter() takes care of it) * fix XFER_MW_DMA0 timings (they were overclocked, use the official ones) * fix bitmasks for clearing bits of register B: - when programming DMA mode bit 0x10 of register B was cleared which resulted in overclocked PIO timing setting (iff PIO0 was used) - when programming PIO mode bits 0x18 weren't cleared so suboptimal timings were used for PIO1-4 if PIO0 was previously set (bit 0x10) and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08) * add FIXME comment about missing locking for 66MHz clock register Also while at it: * remove unused defines * do a few cosmetic / CodingStyle fixes * bump driver version v2: * in pdc202xx_tune_chipset() the old content of drive configuration registers is used only by the debugging code so cover "drive_conf" PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO (Noticed by Sergei Shtylyov) Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

It was agreed that phy-connection-type was a better name for the interface-type property, so this patch renames it. Also, the max-speed property name was determined too generic, and is therefore eliminated in favour of phy-connection-type derivation logic. includes corrections to copyright text.

After examining what was checked in and the code base I discovered that most of 86c0baf1 wasn't necessary anymore.... So here's a patch that reverts the last part of that changeset: Revert part of 86c0baf1. The kernel has moved forward to a state where the original change is not necessary.
