pata_sis: code style cleanups for consistency

2011-10-08T04:07:16+00:00

Remove a lot of '  ' (double spaces) as well as ensuring use of tabs vs.
spaces is appropriate and consistent.

pata_sis: mark most const data static as well

2011-10-08T04:07:16+00:00

This pushes timing and other values into preinitialized read-only data
sections rather than being inlined into the code. None of these
functions are called more than a handful of times, so reducing code size
makes sense.

pata_sis: enable MWDMA for UDMA 133 chipset

2011-10-08T04:07:16+00:00

This ports the timing values over from the old IDE driver into the new
PATA-based one. The comment was lying when it stated the old driver was
not MWDMA capable.

Boot tested on actual hardware using 'libata.force=mwdma2'.

pata_sis: add mode_filter method for certain sis5513 chipsets

2011-10-08T04:07:15+00:00

This mirrors a very old commit (3160d5416f39da9d9, "sis5513: add
->udma_filter method for chipset_family >= ATA_133") to the old sis5513
IDE driver that prevents certain setups from working.

UDMA6 (ATA/133) is not supported on some chipsets and we need to ensure
this mode is not chosen even if a connected drive supports it. Port this
old patch forward to the new PATA driver to ensure UDMA5 is the highest
mode used if that is what is supported.

Kernel bugzilla #41582.

pata_sis: extract a sis_port_base() method

2011-10-08T04:07:15+00:00

This is similar to the existing sis_old_port_base() method. We do this
same calculation and logic in multiple places (with one more to come in
a future patch), so extracting it into a method makes sense.

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: remove ATA_FLAG_{SRST|SATA_RESET}

2011-03-02T07:36:46+00:00

These flags are marked as obsolete and the checks for them have been removed
by commit 294440887b32c58d220fb54b73b7a58079b78f20 (libata-sff: kill unused
ata_bus_reset()), so I think it's time to finally get rid of them...

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.
