pata_it8213: add UDMA100 and UDMA133 support

2011-10-14T17:25:13+00:00

Fixes IDE -> libata regression.

IDE's it8213 host driver has been supporting those modes
(per official documentation) since the initial driver's merge
on Feb 7 2007 (commit 9c6712c0 "ide: add it8213 IDE driver").

ata: Add and use ata_print_version_once

2011-07-23T21:57:36+00:00

Use a single mechanism to show driver version.
Reduces text a tiny bit too.

Remove uses of static int printed_version
Add and use ata_print_version(const struct device *, const char *ver)
and ata_print_version_once.

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.

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.

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.

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.
