* 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 <bzolnier@gmail.com>
