PNP: Allow console to override ACPI device sleep

2015-02-02T18:11:25+00:00

If the serial console is an ACPI PNP device, the PNP bus always powers
down the device at system suspend, even though the no_console_suspend
command line parameter is specified (eg., when debugging suspend/resume).

Add PNP_CONSOLE capability, which when set, prevents calling both the
->disable() and ->suspend() PNP protocol methods if console suspend
is disabled.

treewide: Convert uses of struct resource to resource_size(ptr)

2011-06-10T12:55:36+00:00

Several fixes as well where the +1 was missing.

Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.

PNPACPI: Add support for remote wakeup

2010-07-18T23:58:48+00:00

This patch (as1354) adds remote-wakeup support to the pnpacpi driver.
The new can_wakeup method also allows other PNP protocol drivers
(pnpbios or iaspnp) to add wakeup support, but I don't know enough
about how they work to actually do it.

PNP: add interface to retrieve ACPI device from a PNPACPI device

2009-12-15T22:35:26+00:00

Add pnp_acpi_device(pnp_dev), which takes a PNP device and returns the
associated ACPI device (or NULL, if the device is not a PNPACPI device).

This allows us to write a PNP driver that can manage both traditional
PNPBIOS and ACPI devices, treating ACPI-only functionality as an optional
extension.

pnp: add a shutdown method to pnp drivers

2009-09-22T14:17:49+00:00

The shutdown method is used by the winbond cir driver to setup the
hardware for wake-from-S5.

Add a PNP resource range check function, indicating whether a resource
has been assigned to any device.

pnp: make the resource type an unsigned long

2008-10-16T18:21:45+00:00

PnP encodes the resource type directly as its struct resource->flags value
which is an unsigned long.  Make it so...

PNP: convert the last few pnp_info() uses to printk()

2008-10-11T03:27:18+00:00

There are only a few remaining uses of pnp_info(), so I just
converted them to printk and removed the pnp_err(), pnp_info(),
pnp_warn(), and pnp_dbg() wrappers.

I also removed a couple debug messages that don't seem useful any
more ("driver registered", "driver unregistered", "driver attached").

Fix PNP build failure, bugzilla #11276

2008-09-17T02:35:05+00:00

This fill fix the following regression list entry:

Bug-Entry	: http://bugzilla.kernel.org/show_bug.cgi?id=11276
Subject		: build error: CONFIG_OPTIMIZE_INLINING=y causes gcc 4.2 to do stupid things
Submitter	: Randy Dunlap 
Date		: 2008-08-06 17:18 (38 days old)
References	: http://marc.info/?l=linux-kernel&m=121804329014332&w=4

Handled-By	: Bjorn Helgaas 
Patch		: http://lkml.org/lkml/2008/7/22/364

with what I believe is a better fix than the one referenced
in the regression entry above.

These PNP header interfaces try to work in such a way that
you can reference some of them even if PNP is not enabled,
and the compiler was expected to optimize everything away.

Which is mostly fine, except that there was one interface
for which there was not provided an inline "NOP" implementation.

Once we add that, all of these compile failures cannot handle
any more.

pnp: Provide NOP inline implementation of pnp_get_resource() when !PNP

Fixes kernel bugzilla #11276.
