PCI: sysfs: Update ROM to include default owner write access
x86/PCI: make Broadcom CNB20LE driver EMBEDDED and EXPERIMENTAL
x86/PCI: don't use native Broadcom CNB20LE driver when ACPI is available
PCI/ACPI: Request _OSC control once for each root bridge (v3)
PCI: enable pci=bfsort by default on future Dell systems
PCI/PCIe: Clear Root PME Status bits early during system resume
PCI: pci-stub: ignore zero-length id parameters
x86/PCI: irq and pci_ids patch for Intel Patsburg
PCI: Skip id checking if no id is passed
PCI: fix __pci_device_probe kernel-doc warning
PCI: make pci_restore_state return void
PCI: Disable ASPM if BIOS asks us to
PCI: Add mask bit definition for MSI-X table
PCI: MSI: Move MSI-X entry definition to pci_regs.h
Fix up trivial conflicts in drivers/net/{skge.c,sky2.c} that had in the
meantime been converted to not use legacy PCI power management, and thus
no longer use pci_restore_state() at all (and that caused trivial
conflicts with the "make pci_restore_state return void" patch)

The PCI sysfs ROM interface requires an enabling write to access the ROM
image, but the default file mode is 0400. The original proposed patch
adding sysfs ROM support was a true read-only interface, with the
enabling bit coming in as a feature request. I suspect it was simply an
oversight that the file mode didn't get updated to match the API.

Move the evaluation of acpi_pci_osc_control_set() (to request control of
PCI Express native features) into acpi_pci_root_add() to avoid calling
it many times for the same root complex with the same arguments.
Additionally, check if all of the requisite _OSC support bits are set
before calling acpi_pci_osc_control_set() for a given root complex.

Commit a1f5f22adc3206c47e70652c12671666c65b579f ("gpio: timbgpio:
irq_data conversion") was slightly too enthusiastic in converting
timbgpio_irq() over to take an irq_data * argument instead of an
unsigned int irq argument, as it is a flow handler, which still take
IRQ numbers for now. (And on top of that, it was using the wrong
accessors.)
This fixes it up, and seems to build without warnings.

The MAX17042 is a fuel gauge with an I2C interface for lithium-ion
betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit
registers. Besides, MAX17042 has much more features than MAX17040; e.g.,
a thermistor, current and current accumulation measurement, battery
internal resistance estimate, average values of measurement, and others.
This patch implements a driver for MAX17042.
In this initial release, we have implemented the most basic features of
a fuel gauge: measure the battery capacity and voltage.

The first releases of LP3974 have a large delay in RTC registers,
which requires 2 seconds of delay after writing to a rtc register
(recommended by National Semiconductor's engineers)
before reading it.
If "rtc_delay" field of the platform data is true, the rtc driver
assumes that such delays are required. Although we have not seen
LP3974s without requiring such delays, we assume that such LP3974s
will be released soon (or they have done so already) and they are
supported by "lp3974" without setting "rtc_delay" at the platform
data.
This patch adds delays with msleep when writing values to RTC registers
if the platform data has rtc_delay set.

The SCx200 ACB driver supports ISA hardware as well as PCI. The PCI
hardware is CS5535/CS5536 based, and the device that it grabs is handled by
the cs5535-mfd driver. This converts the SCx200 driver to use a
platform_driver rather than the previous PCI hackery.
The driver used to manually track the iface list (via linked list); now it
only does this for ISA devices. PCI ifaces are handled through standard
driver model lists.
It's unclear what happens in case of errors in the old ISA code; rather than
pretending the code actually cares, I've dropped the (implicit) ignorance
of return values and marked it with a comment.

Since we don't have a PWM API every PWM driver ends up exporting its
own version and we need to limit the platforms we try to build them on
in order to avoid multiple definitions. As the AB8500 is normally a
companion chip for the U8500 CPU depend on that architecture.

... and convert it to a dev_info print at probe time.
There are many variants of this chip with different values of VERSIONCRC.
The set of values is large, and not useful to enumerate. All are SW
compatible. The difference lies in default settings of the various power
rails, and other similar differences. The driver, or clients of the
driver, shouldn't be affected by this, since all rails should be
programmed into the desired state in all cases for correct operation.
