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/ide-probe.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'drivers/ide/ide-probe.c') diff --git a/drivers/ide/ide-probe.c b/drivers/ide/ide-probe.c index b58eb792172e..a4b65b321f51 100644 --- a/drivers/ide/ide-probe.c +++ b/drivers/ide/ide-probe.c @@ -843,7 +843,7 @@ static void ide_port_tune_devices(ide_hwif_t *hwif) drive->nice1 = 1; - if (hwif->dma_host_set) + if (hwif->dma_ops) ide_set_dma(drive); } } @@ -1390,7 +1390,8 @@ static void ide_init_port(ide_hwif_t *hwif, unsigned int port, hwif->swdma_mask = 0; hwif->mwdma_mask = 0; hwif->ultra_mask = 0; - } + } else if (d->dma_ops) + hwif->dma_ops = d->dma_ops; } if (d->host_flags & IDE_HFLAG_RQSIZE_256) -- cgit v1.2.3
