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.

ata: delete non-required instances of include

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.

pata_cs5536: add quirk for broken udma

2012-11-28T17:38:41+00:00

I am working on a device which uses the cs5536 pata driver. There
are some broken hardware revisions out in the field, which can be
detected via DMI. On older versions with an embedded BIOS I
used libata.dma=0 to disable dma completely.
Now we are switching to a coreboot/seabios based BIOS where we
have DMI support and so I think its a good idea to get rid of
all those hacky kernel parameters as the same image
is used other devices where libata.dma=0 is not a good idea.

ata: use module_pci_driver

2012-07-25T19:12:11+00:00

This patch converts the drivers in drivers/ata/* to use module_pci_driver()
macro which makes the code smaller and a bit simpler.

pata_cs5536: forward port changes from cs5536

2012-01-09T00:14:58+00:00

* Fix cable detection to also account for the slave device cable bit.

* Disable UDMA when programming MWDMA in cs5536_set_dmamode().

* Don't change UDMA settings in cs5536_set_piomode().

* Add cs5536_program_dtc() helper.

* Cleanup and uninline cs5536_[read,write]() methods.

pata_cs5536: avoid implicit MSR API inclusion on x86-64

2010-12-27T00:42:15+00:00

We don't need or want MSR usage here, on x86-64.
x86-64 was disabled intentionally in Kconfig, but commit
9272dcc232b84ccb027d6861077934055d42764d changed that.

pata_cs5536: Add support for non-X86_32 platforms

2010-12-24T18:33:23+00:00

pata_cs5536 does work on the other platforms(e.g. Loongson, a MIPS
variant), so, remove the dependency of X86_32 and fix the building
errors under the other platforms via only reserving the X86_32 specific
parts for X86_32.

pata_amd also supports cs5536 IDE controller, but this one saves about
33k for the compressed kernel image(vmlinuz for MIPS).

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.
