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-iops.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'drivers/ide/ide-iops.c') diff --git a/drivers/ide/ide-iops.c b/drivers/ide/ide-iops.c index bfec5d066b25..9c646bd63549 100644 --- a/drivers/ide/ide-iops.c +++ b/drivers/ide/ide-iops.c @@ -432,7 +432,7 @@ int drive_is_ready (ide_drive_t *drive) u8 stat = 0; if (drive->waiting_for_dma) - return hwif->ide_dma_test_irq(drive); + return hwif->dma_ops->dma_test_irq(drive); #if 0 /* need to guarantee 400ns since last command was issued */ @@ -703,8 +703,8 @@ int ide_config_drive_speed(ide_drive_t *drive, u8 speed) // msleep(50); #ifdef CONFIG_BLK_DEV_IDEDMA - if (hwif->dma_host_set) /* check if host supports DMA */ - hwif->dma_host_set(drive, 0); + if (hwif->dma_ops) /* check if host supports DMA */ + hwif->dma_ops->dma_host_set(drive, 0); #endif /* Skip setting PIO flow-control modes on pre-EIDE drives */ @@ -762,8 +762,8 @@ int ide_config_drive_speed(ide_drive_t *drive, u8 speed) #ifdef CONFIG_BLK_DEV_IDEDMA if ((speed >= XFER_SW_DMA_0 || (hwif->host_flags & IDE_HFLAG_VDMA)) && drive->using_dma) - hwif->dma_host_set(drive, 1); - else if (hwif->dma_host_set) /* check if host supports DMA */ + hwif->dma_ops->dma_host_set(drive, 1); + else if (hwif->dma_ops) /* check if host supports DMA */ ide_dma_off_quietly(drive); #endif -- cgit
