      PM / Wakeirq: Add automated device wake IRQ handling · 4990d4fe
      Tony Lindgren authored
      Turns out we can automate the handling for the device_may_wakeup()
      quite a bit by using the kernel wakeup source list as suggested
      by Rafael J. Wysocki <rjw@rjwysocki.net>.
      
      And as some hardware has separate dedicated wake-up interrupt
      in addition to the IO interrupt, we can automate the handling by
      adding a generic threaded interrupt handler that just calls the
      device PM runtime to wake up the device.
      
      This allows dropping code from device drivers as we currently
      are doing it in multiple ways, and often wrong.
      
      For most drivers, we should be able to drop the following
      boilerplate code from runtime_suspend and runtime_resume
      functions:
      
      	...
      	device_init_wakeup(dev, true);
      	...
      	if (device_may_wakeup(dev))
      		enable_irq_wake(irq);
      	...
      	if (device_may_wakeup(dev))
      		disable_irq_wake(irq);
      	...
      	device_init_wakeup(dev, false);
      	...
      
      We can replace it with just the following init and exit
      time code:
      
      	...
      	device_init_wakeup(dev, true);
      	dev_pm_set_wake_irq(dev, irq);
      	...
      	dev_pm_clear_wake_irq(dev);
      	device_init_wakeup(dev, false);
      	...
      
      And for hardware with dedicated wake-up interrupts:
      
      	...
      	device_init_wakeup(dev, true);
      	dev_pm_set_dedicated_wake_irq(dev, irq);
      	...
      	dev_pm_clear_wake_irq(dev);
      	device_init_wakeup(dev, false);
      	...

      PM / Runtime: Update last_busy in rpm_resume · 56f487c7
      Tony Lindgren authored
      If we don't update last_busy in rpm_resume, devices can go back
      to sleep immediately after resume. This happens at least in
      cases where the device has been powered off and does not have
      any interrupt pending until there's something in the FIFO.

      drm: Zero out invalid vblank timestamp in drm_update_vblank_count. · fdb68e09
      Mario Kleiner authored
      Since commit 844b03f2 we make
      sure that after vblank irq off, we return the last valid
      (vblank count, vblank timestamp) pair to clients, e.g., during
      modesets, which is good.
      
      An overlooked side effect of that commit for kms drivers without
      support for precise vblank timestamping is that at vblank irq
      enable, when we update the vblank counter from the hw counter, we
      can't update the corresponding vblank timestamp, so now we have a
      totally mismatched timestamp for the new count to confuse clients.
      
      Restore old client visible behaviour from before Linux 3.17, but
      zero out the timestamp at vblank counter update (instead of disable
      as in original implementation) if we can't generate a meaningful
      timestamp immediately for the new vblank counter. This will fix
      this regression, so callers know they need to retry again later
      if they need a valid timestamp, but at the same time preserves
      the improvements made in the commit mentioned above.
