ide: fix pmac breakage

2007-03-03T16:48:54Z

Fix breakage added in the IDE devel tree. Add header, then fix drivers/ide/ppc/pmac.c: In function `pmac_ide_setup_dma': drivers/ide/ppc/pmac.c:2044: warning: assignment from incompatible pointer type drivers/ide/ppc/pmac.c: In function `pmac_ide_dma_host_on': drivers/ide/ppc/pmac.c:1989: warning: control reaches end of non-void function include/linux/pci.h: In function `pmac_ide_init': drivers/ide/ppc/pmac.c:1563: warning: ignoring return value of `pci_register_driver', declared with attribute warn_unused_result Then add some apparently-long-missing error handling.

ide: make ide_hwif_t.ide_dma_host_on void (v2)

2007-02-17T01:40:26Z

* since ide_hwif_t.ide_dma_host_on is called either when drive->using_dma == 1 or when return value is discarded make it void, also drop "ide_" prefix * make __ide_dma_host_on() void and drop "__" prefix v2: * while at it rename atiixp_ide_dma_host_on() to atiixp_dma_host_on() and sgiioc4_ide_dma_host_on() to sgiioc4_dma_host_on(). [ Noticed by Sergei Shtylyov . ] Signed-off-by: Bartlomiej Zolnierkiewicz

ide: make ide_hwif_t.ide_dma_{host_off,off_quietly} void (v2)

2007-02-17T01:40:26Z

* since ide_hwif_t.ide_dma_{host_off,off_quietly} always return '0' make these functions void and while at it drop "ide_" prefix * fix comment for __ide_dma_off_quietly() * make __ide_dma_{host_off,off_quietly,off}() void and drop "__" prefix v2: * while at it rename atiixp_ide_dma_host_off() to atiixp_dma_host_off(), sgiioc4_ide_dma_{host_off,off_quietly}() to sgiioc4_dma_{host_off,off_quietly}() and sl82c105_ide_dma_off_quietly() to sl82c105_dma_off_quietly() [ Noticed by Sergei Shtylyov . ] Signed-off-by: Bartlomiej Zolnierkiewicz

ide: add ide_set_dma() helper (v2)

2007-02-17T01:40:26Z

* add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return -1 when DMA needs to be disabled (== need to call ->ide_dma_off_quietly) 0 when DMA needs to be enabled (== need to call ->ide_dma_on) 1 when DMA setting shouldn't be changed * fix IDE code to use ide_set_dma() instead if using ->ide_dma_check directly v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz

ide: disable DMA in ->ide_dma_check for "no IORDY" case (v2)

2007-02-17T01:40:25Z

If DMA is unsupported ->ide_dma_check should disable DMA. v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz

ide: convert ide_hwif_t.mmio into flag (v2)

2007-02-17T01:40:25Z

All users of ->mmio == 1 are gone so convert ->mmio into flag. Noticed by Alan Cox. v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz

ide: use PIO/MMIO operations directly where possible (v2)

2007-02-17T01:40:25Z

This results in smaller/faster/simpler code and allows future optimizations. Also remove no longer needed ide[_mm]_{inl,outl}() and ide_hwif_t.{INL,OUTL}. v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz

ide: add ide_use_fast_pio() helper (v3)

2007-02-17T01:40:25Z

* add ide_use_fast_pio() helper for use by host drivers * add DMA capability and hwif->autodma checks to ide_use_dma() - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1) [ for the IT8211/2 in SMART mode this check shouldn't be made but since in it821x_fixups() we set DMA bit explicitly: if(strstr(id->model, "Integrated Technology Express")) { /* In raid mode the ident block is slightly buggy We need to set the bits so that the IDE layer knows LBA28. LBA48 and DMA ar valid */ id->capability |= 3; /* LBA28, DMA */ we are better off using generic helper if we can ] - ide-cris driver didn't set ->autodma [ before the patch hwif->autodma was only checked in the chipset specific hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check() function so there no behavior change here ] v2: * updated patch description (thanks to Alan Cox for the feedback) v3: * updated for scc_pata driver Signed-off-by: Bartlomiej Zolnierkiewicz
