sata_sil: disable trim

2015-11-30T15:02:49+00:00

When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any
TRIM command results in I/O errors being reported in the log. There is
other similar error reported with TRIM and the SIL controller:
https://bugs.centos.org/view.php?id=5880

Apparently the controller doesn't support TRIM commands. This patch
disables TRIM support on the SATA SIL controller.

ata: remove deprecated use of pci api

2015-04-08T14:55:05+00:00

Replace occurences of the pci api by appropriate call to the dma api.

ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host drivers

2014-05-10T02:37:49+00:00

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM
where applicable.  Benefits of this change:

* unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n
  and CONFIG_PM_RUNTIME=y configurations

* easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in
  the future

* more consistent code (there are host drivers which are using the correct
  CONFIG_PM_SLEEP checks already)

The patch leaves the core libata code and ->port_[suspend,resume] support
in sata_[inic162x,nv,sil24].c alone for now.

Merge branch 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2014-03-31T22:27:37+00:00

Pull libata updates from Tejun Heo:
 "A lot of activities on libata side this time.

   - A lot of changes around ahci.  Various embedded platforms are
     implementing ahci controllers.  Some were built atop ahci_platform,
     others were doing their own things.  Hans made some structural
     changes to libahci and librarized ahci_platform so that ahci
     platform drivers can share more common code.  A couple platform
     drivers are added on top of that and several are added to replace
     older drivers which were doing their own things (older ones are
     scheduled to be removed).

   - Dan finishes the patchset to make libata PM operations
     asynchronous.  Combined with one patch being routed through scsi,
     this should speed resume measurably.

   - Various fixes and cleanups from Bartlomiej and others"

2014-02-13T21:40:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

sata_sil: apply MOD15WRITE quirk to TOSHIBA MK2561GSYN

2014-02-03T15:42:07+00:00

It's a bit odd to see a newer device showing mod15write; however, the
reported behavior is highly consistent and other factors which could
contribute seem to have been verified well enough.  Also, both
sata_sil itself and the drive are fairly outdated at this point making
the risk of this change fairly low.  It is possible, probably likely,
that other drive models in the same family have the same problem;
however, for now, let's just add the specific model which was tested.

Merge branch 'libata/for-3.10-fixes' into libata/for-3.11

2013-07-03T02:54:16+00:00

libata/for-3.10-fixes never got submitted during v3.10 cycle.  Merge
it into for-3.11 so that it can be routed together with other changes
scheduled for v3.11.

Three trivial conflicts in drivers/ata/sata_rcar.c.  All are caused by
1b20f6a9ad ("sata_rcar: add 'base' local variable to some functions")
conflicting with logic updates in for-3.10-fixes.  The offending
commit simply adds local variable @base on functions which
dereferences sata_rcar_priv->base multiple times.  The resolutions are
trivial - applying s/priv->base/base/ in the conflicting logic
updates.

ata: use pci_get_drvdata()

2013-06-03T05:22:03+00:00

Use the wrapper function for getting the driver data using pci_dev
instead of using dev_get_drvdata() with &pdev->dev, so we can directly
pass a struct pci_dev.  This is a purely cosmetic change.
