2011-12-21PM: Drop generic_subsys_pm_opsRafael J. Wysocki
Since the PM core is now going to execute driver callbacks directly if the corresponding subsystem callbacks are not present, forward-only subsystem callbacks (i.e. such that only execute the corresponding driver callbacks) are not necessary any more. Thus it is possible to remove generic_subsys_pm_ops, because the only callback in there that is not forward-only, .runtime_idle, is not really used by the only user of generic_subsys_pm_ops, which is vio_bus_type. However, the generic callback routines themselves cannot be removed from generic_ops.c, because they are used individually by a number of subsystems. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-12-21PM / Sleep: Remove forward-only callbacks from AMBA bus typeRafael J. Wysocki
The forward-only PM callbacks provided by the AMBA bus type are not necessary any more, because the PM core executes driver callbacks when the corresponding subsystem callbacks are not present, so drop them. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-12-21PM / Sleep: Remove forward-only callbacks from platform bus typeRafael J. Wysocki
The forward-only PM callbacks provided by the platform bus type are not necessary any more, because the PM core executes driver callbacks when the corresponding subsystem callbacks are not present, so drop them. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-12-21PM: Run the driver callback directly if the subsystem one is not thereRafael J. Wysocki
Make the PM core execute driver PM callbacks directly if the corresponding subsystem callbacks are not present. There are three reasons for doing that. First, it reflects the behavior of drivers/base/dd.c:really_probe() that runs the driver's .probe() callback directly if the bus type's one is not defined, so this change will remove one arbitrary difference between the PM core and the remaining parts of the driver core. Second, it will allow some subsystems, whose PM callbacks don't do anything except for executing driver callbacks, to be simplified quite a bit by removing those "forward-only" callbacks. Finally, it will allow us to remove one level of indirection in the system suspend and resume code paths where it is not necessary, which is going to lead to less debug noise with initcall_debug passed in the kernel command line (messages won't be printed for driverless devices whose subsystems don't provide PM callbacks among other things).

2011-12-21PM / Sleep: Make pm_op() and pm_noirq_op() return callback pointersRafael J. Wysocki
Make the pm_op() and pm_noirq_op() functions return pointers to appropriate callbacks instead of executing those callbacks and returning their results. This change is required for a subsequent modification that will execute the corresponding driver callback if the subsystem callback returned by either pm_op(), or pm_noirq_op() is NULL.

2011-12-19Revert "mmc: enable runtime PM by default"Ohad Ben-Cohen
When SDIO runtime PM was originally introduced, we immediately faced two regressions with two different chipsets, and in response decided not to enable it by default. With the recent work on the 8686 we hoped we found all the gotchas, so 08da834 did make sense (at least experimentally). Unfortunately we now see that some setups out there still refuse to work when SDIO runtime PM is enabled by default (see http://www.spinics.net/lists/linux-mmc/msg11161.html), and obviously we can't live with these kind of regressions.

Change oprofilefs_ulong_from_user()'s interface to return count on success. Thus, we are able to return early if count equals zero which avoids using *val uninitialized.

2011-12-18PM / Sleep: Simplify generic system suspend callbacksRafael J. Wysocki
The pm_runtime_suspended() check in __pm_generic_call() doesn't really help and may cause problems to happen, because in some cases the system suspend callbacks need to be called even if the given device has been suspended by runtime PM. For example, if the device generally supports remote wakeup and is not enabled to wake up the system from sleep, it should be prevented from generating wakeup signals during system suspend and that has to be done by the suspend callbacks that the pm_runtime_suspended() check prevents from being executed. Similarly, it may not be a good idea to unconditionally change the runtime PM status of the device to 'active' in __pm_generic_resume(), because the driver may want to leave the device in the 'suspended' state, depending on what happened to it before the system suspend and whether or not it is enabled to wake up the system. For the above reasons, remove the pm_runtime_suspended() check from __pm_generic_call() and remove the code changing the device's runtime PM status from __pm_generic_resume().

2011-12-16drm/i915/dp: Dither down to 6bpc if it makes the mode fitAdam Jackson
Some active adaptors (VGA usually) only have two lanes at 2.7GHz. That's a maximum pixel clock of 144MHz at 8bpc, but 192MHz at 6bpc. Fixes Asus UX31 panel being black at startup due to no valid modes since dc22ee6fc18ce0f15424e753e8473c306ece95c1. v2: Rebased to current code, resulting in the fix applying to EDP panels as well. Also changed from spatio-temporal to just spatial dithering on pre-ironlake, to be conssitent (and less visual flicker) Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Eric Anholt <eric@anholt.net> Tested-by: Eric Anholt <eric@anholt.net> Tested-by: Dirk Hohndel <hohndel@infradead.org> Signed-off-by: Keith Packard <keithp@keithp.com>
