Bjorn Helgaas 2cd1393098 PNP: remove unused interfaces using pnp_resource_table
Rene Herman <rene.herman@gmail.com> recently removed the only in-tree
driver uses of:

    pnp_init_resource_table()
    pnp_manual_config_dev()
    pnp_resource_change()

in this change:

    http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=109c53f840e551d6e99ecfd8b0131a968332c89f

These are no longer used in the PNP core either, so we can just remove
them completely.

It's possible that there are out-of-tree drivers that use these
interfaces.  They should be changed to either (1) use PNP quirks
to work around broken hardware or firmware, or (2) use the sysfs
interfaces to control resource usage from userspace.

Bjorn Helgaas 6969c7ed55 PNP: remove pnp_resource_table from internal pnp_clean_resource_table interface
This changes pnp_clean_resource_table() to take a pnp_dev pointer
rather than a pnp_resource_table pointer.  This reduces the visibility
of pnp_resource_table and removes an opportunity for error in the
caller.

Bjorn Helgaas f449000209 PNP: add pnp_init_resources(struct pnp_dev *) interface
Add pnp_init_resources(struct pnp_dev *) to replace
pnp_init_resource_table(), which takes a pointer to the
pnp_resource_table itself.  Passing only the pnp_dev * reduces
the possibility for error in the caller and removes the
pnp_resource_table implementation detail from the interface.

Even though pnp_init_resource_table() is exported, I did not
export pnp_init_resources() because it is used only by the PNP
core.

Bjorn Helgaas 81b5c75f0e PNP: add debug when assigning PNP resources
This patch adds code to dump PNP resources before and after
assigning resources and before writing them to the device.

This is enabled by CONFIG_PNP_DEBUG=y.

Bjorn Helgaas 4ab55d8d4f PNP: remove more pnp_resource_table arguments
Stop passing around struct pnp_resource_table pointers.  In most cases,
the caller doesn't need to know how the resources are stored inside
the struct pnp_dev.

Bjorn Helgaas 59284cb409 PNP: remove pnp_resource_table from internal get/set interfaces
When we call protocol->get() and protocol->set() methods, we currently
supply pointers to both the pnp_dev and the pnp_resource_table even
though the pnp_resource_table should always be the one associated with
the pnp_dev.

This removes the pnp_resource_table arguments to make it clear that
these methods only operate on the specified pnp_dev.

Bjorn Helgaas cd7ec927d9 PNPACPI: extend irq_flags() to set IORESOURCE_IRQ_SHAREABLE when appropriate
This simplifies IRQ resource parsing slightly by computing all the
IORESOURCE_IRQ_* flags at the same time.

This also keeps track of shareability information when parsing options
from _PRS.  Previously we ignored shareability in _PRS.

Bjorn Helgaas f7e8466a04 PNPACPI: pnpacpi_encode_ext_irq() wrongly set "irq" instead of "extended_irq"
pnpacpi_encode_ext_irq() should set resource->data.extended_irq, not
resource->data.irq.

This has been wrong since at least 2.6.12.  I haven't seen any bug
reports, but it's clearly incorrect.

Split the pnp_add_card_id() part from the PNPID conversion part so we
can move the initial add_id() into the pnp_card allocation.

This makes the PNPID conversion generic so we can use the same
one for both devices and cards.

PNPACPI uses the conversion done by the ACPI core with

Bjorn Helgaas 4a49049864 PNPACPI: continue after _CRS and _PRS errors
Keep going and register the device even if we have trouble parsing
_CRS or _PRS.  A parsing problem might mean we ignore some resources
the device is using, or we might not be able to change its resources.
But we should still take note of anything we *could* parse correctly.

Also remove reference to dev_id because I plan to remove it soon.
