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.Signed-off-by: Bartlomiej Zolnierkiewicz

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.Cc: linux-ide@vger.kernel.org

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.Cc: Bill Pemberton

Separate out ata_pci_bmdma_prepare_host() and ata_pci_bmdma_init_one()

BMDMA or set PCI master.Signed-off-by: Tejun Heo
Signed-off-by: Jeff Garzik -
Separate out BMDMA irq handler from SFF irq handler. The misnamed
host_intr() functions are renamed to ata_sff_port_intr() and
ata_bmdma_port_intr(). Common parts are factored into
__ata_sff_port_intr() and __ata_sff_interrupt() and used by sff and
bmdma interrupt routines.All BMDMA drivers now use ata_bmdma_interrupt() or
ata_bmdma_port_intr() while all non-BMDMA SFF ones use
ata_sff_interrupt() or ata_sff_port_intr().For now, ata_pci_sff_init_one() uses ata_bmdma_interrupt() as it's
used by both SFF and BMDMA drivers.Signed-off-by: Tejun Heo

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

port_info->private_data is currently used for two purposes - to record
private data about the port_info or to specify host->private_data to
use when allocating ata_host.This overloading is confusing and counter-intuitive in that
port_info->private_data becomes host->private_data instead of
port->private_data. In addition, port_info and host don't correspond
to each other 1-to-1. Currently, the first non-NULL
port_info->private_data is used.This patch makes port_info->private_data just be what it is -
private_data for the port_info where LLD can jot down extra info.
libata no longer sets host->private_data to the first non-NULL
port_info->private_data, @host_priv argument is added to
ata_pci_init_one() instead. LLDs which use ata_pci_init_one() can use
this argument to pass in pointer to host private data. LLDs which
don't should use init-register model anyway and can initialize
host->private_data directly.Adding @host_priv instead of using init-register model for LLDs which
use ata_pci_init_one() is suggested by Alan Cox.Signed-off-by: Tejun Heo

ata_pci_init_one() is the only function which uses ops->irq_handler
and pi->sht. Other initialization functions take the same information
as arguments. This causes confusion and duplicate unused entries in
structures.Make ata_pci_init_one() take sht as an argument and use ata_interrupt
implicitly. All current users use ata_interrupt and if different irq
handler is necessary open coding ata_pci_init_one() using
ata_prepare_sff_host() and ata_activate_sff_host can be done under ten
lines including error handling and driver which requires custom
interrupt handler is likely to require custom initialization anyway.As ata_pci_init_one() was the last user of ops->irq_handler, this
patch also kills the field.Signed-off-by: Tejun Heo

libata lets low level drivers build ata_port_operations table and
register it with libata core layer. This allows low level drivers
high level of flexibility but also burdens them with lots of
boilerplate entries.This becomes worse for drivers which support related similar
controllers which differ slightly. They share most of the operations
except for a few. However, the driver still needs to list all
operations for each variant. This results in large number of
duplicate entries, which is not only inefficient but also error-prone
as it becomes very difficult to tell what the actual differences are.This duplicate boilerplates all over the low level drivers also make
updating the core layer exteremely difficult and error-prone. When
compounded with multi-branched development model, it ends up
accumulating inconsistencies over time. Some of those inconsistencies
cause immediate problems and fixed. Others just remain there dormant
making maintenance increasingly difficult.To rectify the problem, this patch implements ata_port_operations
inheritance. To allow LLDs to easily re-use their own ops tables
overriding only specific methods, this patch implements poor man's
class inheritance. An ops table has ->inherits field which can be set
to any ops table as long as it doesn't create a loop. When the host
is started, the inheritance chain is followed and any operation which
isn't specified is taken from the nearest ancestor which has it
specified. This operation is called finalization and done only once
per an ops table and the LLD doesn't have to do anything special about
it other than making the ops table non-const such that libata can
update it.libata provides four base ops tables lower drivers can inherit from -
base, sata, pmp, sff and bmdma. To avoid overriding these ops
accidentaly, these ops are declared const and LLDs should always
inherit these instead of using them directly.After finalization, all the ops table are identical before and after
the patch except for setting .irq_handler to ata_interrupt in drivers
which didn't use to. The .irq_handler doesn't have any actual effect
and the field will soon be removed by later patch.* sata_sx4 is still using old style EH and currently doesn't take
advantage of ops inheritance.Signed-off-by: Tejun Heo

libata lets low level drivers build scsi_host_template and register it
to the SCSI layer. This allows low level drivers high level of
flexibility but also burdens them with lots of boilerplate entries.This patch implements SHT initializers which can be used to initialize
all the boilerplate entries in a sht. Three variants of them are
implemented - BASE, BMDMA and NCQ - for different types of drivers.
Note that entries can be overriden by putting individual initializers
after the helper macro.All sht tables are identical before and after this patch.

PCI device should be powered up or powered up before its PCI regsiters
are accessed. Although PCI configuration register access is allowed
in D3hot, PCI device is free to reset its status when transiting from
D3hot to D0 causing configuration data to change.Many libata SFF drivers which use ata_pci_init_one() read and update
configuration registers before calling ata_pci_init_one() which
enables the PCI device. Also, in resume paths, some drivers access
registers without resuming the PCI device.This patch adds a call to pcim_enable_device() in init path if
register is accessed before calling ata_pci_init_one() and make resume
paths first resume PCI devices, access PCI configuration regiters then
resume ATA host.While at it...
* cmd640 was strange in that it set ->resume even when CONFIG_PM is
not. This is by-product of minimal build fix. Updated.* In cs5530, Don't BUG() on reinit failure. Just whine and fail

There have been reported regressions of the SIL 680 driver when using MMIO, so
this makes it only try MMIO on Cell blades where it's known to be necessary

This patch adds MMIO support to the pata_sil680 for taskfile IOs,
based on what the old siimage does.I haven't bothered changing the chip setup stuff from PCI config
cycles to MMIO though (siimage does it), I don't think it matters,
I've only adapted it to use MMIO for taskfile accesses.I've tested it on a Cell blade and it seems to work fine.
