libata-sff: separate out BMDMA init

2010-05-25T23:40:30+00:00

Separate out ata_pci_bmdma_prepare_host() and ata_pci_bmdma_init_one() from their SFF counterparts. SFF ones no longer try to initialize BMDMA or set PCI master. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

libata: Pass host flags into the pci helper

2010-03-01T19:58:46+00:00

This allows parallel scan and the like to be set without having to stop using the existing full helper functions. This patch merely adds the argument and fixes up the callers. It doesn't undo the special cases already in the tree or add any new parallel callers. Signed-off-by: Alan Cox Signed-off-by: Jeff Garzik

pata_it8213: fix wrong MWDMA timings being programmed

2009-12-03T21:01:39+00:00

Clear old MWDMA timings before programming new ones (IT8213 is a single port host so there is no need to check ap->port_no). This change should be safe as this is how we have been doing things in IDE it8213 host driver for years. Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jeff Garzik

pata_it8213: fix PIO2 underclocking

2009-12-03T21:01:13+00:00

[ port of Sergei's fixes for pata_efar from commit 5f33b3b ] Fix the PIO mode 2 using mode 0 timings -- this driver should enable the fast timing bank starting with PIO2, just like the PIIX/ICH drivers do. Also, fix/rephrase some comments while at it. Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jeff Garzik

pata_it8213: fix wrong PIO timings being programmed

2009-12-03T21:00:56+00:00

* do not clear PIO timings for master when programming slave * program new PIO timings in the correct register nibble Both changes should be safe as this is how we have been doing things in IDE it8213 host driver for years. Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jeff Garzik

pata_it8213: fix UDMA handling

2009-12-03T20:59:25+00:00

Driver should program the cycle timing not the mode number (doing the latter results in wrong timings being used). There shouldn't be any problems with it as IDE it8213 host driver has been doing it this way for years. Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jeff Garzik

[libata] convert drivers to use ata.h mode mask defines

libata: rename SFF functions

2008-04-17T19:44:21+00:00

SFF functions have confusing names. Some have sff prefix, some have bmdma, some std, some pci and some none. Unify the naming by... * SFF functions which are common to both BMDMA and non-BMDMA are prefixed with ata_sff_. * SFF functions which are specific to BMDMA are prefixed with ata_bmdma_. * SFF functions which are specific to PCI but apply to both BMDMA and non-BMDMA are prefixed with ata_pci_sff_. * SFF functions which are specific to PCI and BMDMA are prefixed with ata_pci_bmdma_. * Drop generic prefixes from LLD specific routines. For example, bfin_std_dev_select -> bfin_dev_select. The following renames are noteworthy. ata_qc_issue_prot() -> ata_sff_qc_issue() ata_pci_default_filter() -> ata_bmdma_mode_filter() ata_dev_try_classify() -> ata_sff_dev_classify() This rename is in preparation of separating SFF support out of libata core layer. This patch strictly renames functions and doesn't introduce any behavior difference. Signed-off-by: Tejun Heo
