Here's the big char/misc driver update for 3.19-rc1
Lots of little things all over the place in different drivers, and a new
subsystem, "coresight" has been added. Full details are in the
shortlog.

After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.
Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/misc/.

Here's the big set of driver patches for char/misc drivers. Nothing
major in here, the shortlog below goes into the details. All have been
in the linux-next tree for a while with no issues.

Calling pm_schedule_suspend from the runtime pm idle callback
may reschedule existing timer, thus in case of frequent runtime
rpm idle call the suspend maybe starved.
Instead we call pm_runtime_autosuspend which is checking if the
timer is already charged.
An example is monitoring device pci config space.
Pci config sysfs handlers calls pci_config_pm_runtime_put/get
helpers which in turns calls to device idle callback

For non wakeable devices we can't use pci runtime framework
as we are not able to wakeup from D3 states.
Instead we create new pg runtime domain that only drives TXE power
gating protocol to reduce the power consumption.
