PNP: fix restoring devices after hibernation

2013-12-05T01:01:55+00:00

On returning from hibernation 'restore' callback is called,
not 'resume'.  Fix it.

PNP: convert bus code to use dev_groups

2013-10-17T01:36:02+00:00

The dev_attrs field of struct bus_type is going away soon, dev_groups
should be used instead.  This converts the PNP bus code to use the
correct field.

pnp: change pnp bus pm_ops to invoke pnp driver dev_pm_ops if specified

2013-09-11T22:58:15+00:00

pnp_bus_suspend() and pnp_bus_resume() invoke legacy pm_ops from
pnp_driver.  Changed pnp_bus_suspend() and pnp_bus_resume() to check if
pnp driver has dev_pm_ops and call.  If dev_pm_ops don't exist, then call
use legacy pm_ops.  Without this change, pnp_driver dev_pm_ops will not
get called.

In addition to the pnp driver bus pm_ops change to invoke driver
dev_pm_ops, this patch set contains changes to rtc-cmos, tpm_tis, and
apple-gmux pnp drivers to convert from legacy pm_ops to dev_pm_ops.

This patch (of 4):

pnp_bus_suspend() and pnp_bus_resume() invoke legacy pm_ops from
pnp_driver.  Changed pnp_bus_suspend() and pnp_bus_resume() to check if
pnp driver has dev_pm_ops and call.  If dev_pm_ops don't exist, then call
use legacy pm_ops.  Without this change, pnp_driver dev_pm_ops will not
get called.

PNP: convert PNP driver bus legacy pm_ops to dev_pm_ops

2013-07-27T01:21:03+00:00

Convert drivers/pnp/driver.c bus legacy pm_ops to dev_pm_ops using
existing suspend and resume routines.  Add freeze interface to
handle PM_EVENT_FREEZE correctly with dev_pm_ops.  pm_op() looks for
freeze interface when the event is PM_EVENT_FREEZE.

PNP / ACPI: Use DEVICE_ACPI_HANDLE() for device ACPI handle access

2011-01-11T20:20:40+00:00

The PNP ACPI driver squirrels the ACPI handles of PNP devices' ACPI
companions, but this isn't correct, because those handles should be
accessed using the DEVICE_ACPI_HANDLE() macro operating on struct
device objects.

Using DEVICE_ACPI_HANDLE() in the PNP ACPI driver instead of the
driver's own copies of the ACPI handles allows us to avoid a problem
with docking stations where a machine docked before suspend to RAM
and undocked while suspended crashes during the subsequent resume (in
that case the ACPI companion of the PNP device in question doesn't
exist any more while the device is being resumed).  It also allows us
to avoid the problem where suspend to RAM fails when the machine was
undocked while suspended before (again, the ACPI companion of the PNP
device is not present any more while it is being suspended).

This change doesn't fix all of the the PNP ACPI driver's problems
with PNP devices in docking stations (generally speaking, the driver
has no idea that devices can come and go and doesn't even attempt to
handle such events), but at least it makes suspend work for the
users of docking stations who don't use the PNP devices located in
there.

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").
