From 5e37bdc081a980dd0d669e6387bcf15ca9666f81 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 26 Apr 2008 22:25:24 +0200 Subject: ide: add struct ide_dma_ops (take 3) Add struct ide_dma_ops and convert core code + drivers to use it. While at it: * Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods. * Drop "ide_" "infixes" from DMA methods. * au1xxx-ide.c: - use auide_dma_{test_irq,end}() directly in auide_dma_timeout() * pdc202xx_old.c: - drop "old_" "infixes" from DMA methods * siimage.c: - add siimage_dma_test_irq() helper - print SATA warning in siimage_init_one() * Remove no longer needed ->init_hwif implementations. v2: * Changes based on review from Sergei: - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/ - s/drive->hwif/hwif/ in idefloppy_pc_intr(). - fix patch description w.r.t. au1xxx-ide changes - fix au1xxx-ide build - fix naming for cmd64*_dma_ops - drop "ide_" and "old_" infixes - s/hpt3xxx_dma_ops/hpt37x_dma_ops/ - s/hpt370x_dma_ops/hpt370_dma_ops/ - use correct DMA ops for HPT302/N, HPT371/N and HPT374 - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/ v3: * Two bugs slipped in v2 (noticed by Sergei): - use correct DMA ops for HPT374 (for real this time) - handle HPT370/HPT370A properly Acked-by: Sergei Shtylyov Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/pci/alim15x3.c | 32 +++++++++++--------------------- 1 file changed, 11 insertions(+), 21 deletions(-) (limited to 'drivers/ide/pci/alim15x3.c') diff --git a/drivers/ide/pci/alim15x3.c b/drivers/ide/pci/alim15x3.c index 5261f308d94..987db35199e 100644 --- a/drivers/ide/pci/alim15x3.c +++ b/drivers/ide/pci/alim15x3.c @@ -652,21 +652,7 @@ static u8 __devinit ali_cable_detect(ide_hwif_t *hwif) return cbl; } -/** - * init_hwif_common_ali15x3 - Set up ALI IDE hardware - * @hwif: IDE interface - * - * Initialize the IDE structure side of the ALi 15x3 driver. - */ - -static void __devinit init_hwif_common_ali15x3 (ide_hwif_t *hwif) -{ - if (hwif->dma_base == 0) - return; - - hwif->dma_setup = &ali15x3_dma_setup; -} - +#ifndef CONFIG_SPARC64 /** * init_hwif_ali15x3 - Initialize the ALI IDE x86 stuff * @hwif: interface to configure @@ -716,9 +702,8 @@ static void __devinit init_hwif_ali15x3 (ide_hwif_t *hwif) if(irq >= 0) hwif->irq = irq; } - - init_hwif_common_ali15x3(hwif); } +#endif /** * init_dma_ali15x3 - set up DMA on ALi15x3 @@ -746,7 +731,7 @@ static int __devinit init_dma_ali15x3(ide_hwif_t *hwif, if (ide_allocate_dma_engine(hwif)) return -1; - ide_setup_dma(hwif, base); + ide_setup_dma(hwif, base, d); return 0; } @@ -758,10 +743,16 @@ static const struct ide_port_ops ali_port_ops = { .cable_detect = ali_cable_detect, }; +static struct ide_dma_ops ali_dma_ops = { + .dma_setup = ali15x3_dma_setup, +}; + static const struct ide_port_info ali15x3_chipset __devinitdata = { .name = "ALI15X3", .init_chipset = init_chipset_ali15x3, +#ifndef CONFIG_SPARC64 .init_hwif = init_hwif_ali15x3, +#endif .init_dma = init_dma_ali15x3, .port_ops = &ali_port_ops, .pio_mask = ATA_PIO5, @@ -806,6 +797,8 @@ static int __devinit alim15x3_init_one(struct pci_dev *dev, const struct pci_dev d.udma_mask = ATA_UDMA5; else d.udma_mask = ATA_UDMA6; + + d.dma_ops = &ali_dma_ops; } else { d.host_flags |= IDE_HFLAG_NO_DMA; @@ -815,9 +808,6 @@ static int __devinit alim15x3_init_one(struct pci_dev *dev, const struct pci_dev if (idx == 0) d.host_flags |= IDE_HFLAG_CLEAR_SIMPLEX; -#if defined(CONFIG_SPARC64) - d.init_hwif = init_hwif_common_ali15x3; -#endif /* CONFIG_SPARC64 */ return ide_setup_pci_device(dev, &d); } -- cgit v1.2.3-70-g09d2
