2013-01-04Drivers: ide: remove __dev* attributes.Greg Kroah-Hartman1-5/+5
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton <wfp5p@virginia.edu> Cc: "David S.

2009-04-30alim15x3: Remove historical hacks, re-enable init_hwif for PowerPCAnton Vorontsov1-7/+3
Some time ago we had to disable init_hwif callback for PowerPC builds. That was because of a historical IRQ overwrite in the driver, which was causing IDE malfunction on the MPC8610HPCD PowerPC boards. It's unclear whether this overwrite is still useful, but it is proven to cause a bit of harm, and today some PowerPC targets (Xilinx ML510, as reported by Roderick Colenbrander) need the init_hwif, so we have to re-enable it and remove the overwrite.

2009-03-31ide: add ->dma_check methodBartlomiej Zolnierkiewicz1-4/+5
* Add (an optional) ->dma_check method for checking if DMA can be used for a given command and fail DMA setup in ide_dma_prepare() if necessary. * Convert alim15x3 and trm290 host drivers to use ->dma_check. * Rename ali15x3_dma_setup() to ali_dma_check() while at it. 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>
2009-03-31ide: add ->dma_clear method and remove ->dma_timeout oneBartlomiej Zolnierkiewicz1-1/+0
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.

2009-03-27ide: add ->dma_timer_expiry method and remove ->dma_exec_cmd one (v2)Bartlomiej Zolnierkiewicz1-1/+1
* 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). There should be no functional changes caused by this patch.

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 Shtylyov1-0/+1
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...
