2009-05-17ide: remove hw_regs_t typedefBartlomiej Zolnierkiewicz
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 Zolnierkiewicz
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.

2009-03-31ide-pmac: IDE cable detection on Apple PowerBookTOMARI Hisanobu
As IDE cable used on Apple PowerBook/iBook laptops are always of "Short 40" type when the firmware says it's 80 conductor one, the cable detection should return ATA_CBL_PATA40_SHORT on those machines. This enables to automatically use UDMA5 even with drives that doesn't correctly detect those cables on Apple laptops.

2009-03-31ide: turn selectproc() method into dev_select() method (take 5)Sergei Shtylyov
Turn selectproc() method into dev_select() method by teaching it to write to the device register and moving it from 'struct ide_port_ops' to 'struct ide_tp_ops'.

2009-03-31ide: set/clear drive->waiting_for_dma flag in the core codeBartlomiej Zolnierkiewicz
Set/clear drive->waiting_for_dma flag in the core code instead of in ->dma_setup and ->dma_end methods. 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>

Move ide_map_sg() call from ->dma_setup implementations and ide_destroy_dmatable() one from *_build_dmatable() to ide_dma_prepare(). There should be no functional changes caused by this patch. Sergei: Removed 'use_pio_instead' labels and replaced 'goto' with 'return 0' -- that required no changes to the follow-up patches...

2009-03-31ide: destroy DMA mappings after ending DMA (v2)Bartlomiej Zolnierkiewicz
Move ide_destroy_dmatable() call out from ->dma_end method to {ide_pc,cdrom_newpc,ide_dma}_intr(), ide_dma_timeout_retry() and sgiioc4_resetproc(). This causes minor/safe behavior changes w.r.t.: * cmd64x.c::cmd64{8,x}_dma_end() * cs5536.c::cs5536_dma_end() * icside.c::icside_dma_end() * it821x.c::it821x_dma_end() * scc_pata.c::__scc_dma_end() * sl82c105.c::sl82c105_dma_end() * tx4939ide.c::tx4939ide_dma_end() v2: * Fix build for CONFIG_BLK_DEV_IDEDMA=n (reported by Randy Dunlap).

2009-03-31ide: add ->dma_clear method and remove ->dma_timeout oneBartlomiej Zolnierkiewicz
All custom ->dma_timeout implementations call the generic one thus it is possible to have only an optional method for resetting DMA engine instead: * Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105 host drivers to use it. * Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove ->dma_timeout method. * Make ide_dma_timeout() static. 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>
2009-03-27ide: add ->dma_timer_expiry method and remove ->dma_exec_cmd one (v2)Bartlomiej Zolnierkiewicz
* Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it. * Add ->dma_timer_expiry method and use it to set hwif->expiry for ATA_PROT_DMA protocol in do_rw_taskfile(). * Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts. * Move setting hwif->expiry from ide_execute_command() to its users and drop 'expiry' argument. * Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile(). * Remove ->dma_exec_cmd method and its implementations. * Unexport ide_execute_command() and ide_dma_intr(). v2: * Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap). * Fix *dma_expiry naming (suggested by Sergei Shtylyov).

2009-03-27ide: pass command to ide_map_sg()Bartlomiej Zolnierkiewicz
* Set IDE_TFLAG_WRITE flag and ->rq also for ATA_CMD_PACKET commands. * Pass command to ->dma_setup method and update all its implementations accordingly. * Pass command instead of request to ide_build_sglist(), *_build_dmatable() and ide_map_sg(). While at it: * Fix scc_dma_setup() documentation + use ATA_DMA_WR define. * Rename sgiioc4_build_dma_table() to sgiioc4_build_dmatable(), change return value type to 'int' and drop unused 'ddir' argument. * Do some minor cleanups in [tx4939]ide_dma_setup().

2009-01-06ide: move read_sff_dma_status() method to 'struct ide_dma_ops'Sergei Shtylyov
Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops' to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only required for SFF-8038i compatible IDE controller drivers (greatly cutting down the number of initializers) as its only user (outside ide-dma-sff.c and such drivers) appears to be ide_pci_check_simplex() which is only called for such controllers...
