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

This MIC virtual bus driver takes the responsibility of creating all
the virtual devices connected to the PCIe device on the host and the
platform device on the card. The MIC bus hardware operations provide
a way to abstract certain hardware details from the base physical devices.
Examples of devices added on the MIC virtual bus include host DMA and card DMA.
This abstraction enables using a common DMA driver on host and card.

GenWQE used to call pci_enable_msi_block to allocate a desired number
of MSI's. If that was not possible pci_enable_msi_block returned with a
smaller number which might be possible to allocate. GenWQE then called
pci_enable_msi_block with that number.
Since commit a30d0108b
"GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()"
pci_enable_msi_exact is used which fails if the desired number of MSI's
was not possible to allocate. Change GenWQE to use pci_enable_msi_range
to restore the old behavior.

Currently, in the event of a fatal hardware error, the driver tries a
recovery procedure that calls pci_reset_function() to reset the card.
This is not sufficient in some cases, needing a fundamental reset to
bring the card back.
This patch implements a call to the platform fundamental reset procedure
on the error recovery path if GENWQE_PLATFORM_ERROR_RECOVERY is enabled.
This is implemented by default only on PPC64, since this can cause
problems on other archs, e.g. zSeries, where the platform has its own
recovery procedures, leading to a potencial race conditition. For these
cases, the recovery is kept as it was before.

This patch implements the callbacks and functions necessary to have EEH
recovery support.
It adds a config option to enable or disable explicit calls to trigger
platform specific mechanisms on error recovery paths. This option is
enabled by default only on PPC64 systems and can be overritten via
debugfs. If this option is enabled, on the error recovery path the
driver will call pci_channel_offline() to check for error condition and
issue non-raw MMIO reads to trigger early EEH detection in case of
hardware failures. This is necessary since the driver MMIO helper
funtions use raw accessors.

"Cleanups for 3.16. Among these are:
- a bunch of misc cleanups for Broadcom platforms, mostly
housekeeping
- enabling Common Clock Framework on the older s3c24xx Samsung
chipsets
- cleanup of the Versatile Express system controller code, moving it
to syscon
- power management cleanups for OMAP platforms
plus a handful of other cleanups across the place"

Function genwqe_free_sync_sgl() returns the value of variable 'rc'. 'rc' is
only set in the error paths, thus initialize it by 0. Coverity CID 1204242.

There is architecture code in mach-at91 that depends on the
CONFIG_ATMEL_PWM symbol in order to call the soc-specific
at91_add_device_pwm function. While all of this is about code
that will be removed in the future, using DT probing and
the PWM framework, we currently get a build failure:
arch/arm/mach-at91/built-in.o: In function `at91_pwm_leds':
arch/arm/mach-at91/leds.c:88: undefined reference to `at91_add_device_pwm'
This patch ensures we only try to build this driver on
platforms on which it will build and work.

According the spec the host should read H_CSR again
after asserting reset H_RST to ensure that reset was
read by the firmware

It my take time till ME_RDY will be cleared after the reset,

We cleared H_RST for H_CSR on spurious interrupt generated when ME_RDY
while cleared and not while ME_RDY is set. The spurious interrupt
is not delivered on all platforms in this case the
driver may fail to initialize.

The pch_phub driver is for a companion chip to the Intel Atom E600
series processors. These are 32-bit x86 processors so the driver is
only needed on X86_32. Add COMPILE_TEST as an alternative, so that the
driver can still be build-tested elsewhere.

This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:
* LEDs code has been completely removed and replaced with
"gpio-leds" nodes in the tree (referencing dedicated
GPIO subnodes in sysreg - bindings documentation updated);
this also better fits the reality as some variants of the
motherboard don't have all the LEDs populated
* syscfg bridge code has been extracted into a separate
driver (placed in drivers/misc for no better place)
* all the ID & MISC registers are defined as sysconf
making them available for other drivers should they need
to use them (and also to the user via /sys/kernel/debug/regmap
which can be helpful in platform debugging)
