Remove duplicate intel_fbc_enabled prototype.
Update kernel inclusions of capability.h to use capsicum.h instead; some
further refinement is required as some device drivers intended to be
portable over FreeBSD versions rely on __FreeBSD_version to decide whether
to include capability.h.

i915 driver - enable opregion handle; program CADL.
add opregion handling for drm2 - which exposes some ACPI video configuration
pieces that some Lenovo laptop models use to flesh out which video device
to speak to. This enables the brightness control in ACPI to work these models.
The CADL bits are also important - it's used to figure out which ACPI
events to hook the brightness buttons into. It doesn't yet seem to work
for me, but it does for the OP.

279573: Sync AHCI driver with HEAD.
Due to code reorganization in r271146 and many previous reordered merges it
is problematic to merge those revisions separately.
We were returning 20 bytes as the FIS size to send, but only
initializing 16. Initialize all 20 so we don't send garbage in the
Auxiliary register. The SATA standard mandates a 5 dword length for
the Host to Device FIS.
Add support for the DWC OTG v2 chipset found in the STM32F4 series of
processors. Make sure we pullup the data lines in device mode when we
power on the port.
Correct a PCI enumeration bug introduced in r264011
Ensure that first_func is set to 0 on every iteration of the PCI slot
enumeration loop after the first. There is a continue statement that would
cause first_func to stay at 1 any PCI device where slot 0 has no functions
until we find a slot that does have a function. This would cause us to
not enumerate the first PCI function on the device.
Credit to markj@ for spotting the bug.

MFC support for PCI Alternate RID Interpretation. ARI is an optional PCIe
feature that allows PCI devices to present up to 256 functions on a bus.
This is effectively a prerequisite for PCI SR-IOV support.

Re-implement the DMAR I/O MMU code in terms of PCI RIDs
Under the hood the VT-d spec is really implemented in terms of
PCI RIDs instead of bus/slot/function, even though the spec makes
pains to convert back to bus/slot/function in examples. However
working with bus/slot/function is not correct when PCI ARI is
in use, so convert to using RIDs in most cases. bus/slot/function
will only be used when reporting errors to a user.

r264011:
Add support for PCIe ARI
PCIe Alternate RID Interpretation (ARI) is an optional feature that
allows devices to have up to 256 different functions. It is
implemented by always setting the PCI slot number to 0 and
re-purposing the 5 bits used to encode the slot number to instead
contain the function number. Combined with the original 3 bits
allocated for the function number, this allows for 256 functions.
This is enabled by default, but it's expected to be a no-op on currently
supported hardware. It's a prerequisite for supporting PCI SR-IOV, and
I want the ARI support to go in early to help shake out any bugs in it.
ARI can be disabled by setting the tunable hw.pci.enable_ari=0.

Ensure that the XHCI driver will refresh the control endpoint settings
when re-enumerating a FULL speed device. Else the wrong max packet
setting might be used when trying to re-enumerate a FULL speed device.
The __FreeBSD_version was changed to 1001510 to be appropriate for
stable/10.
I will followup with a commit to mpr(4) and mps(4) in head to reflect
the stable/10 __FreeBSD_version and merge the change back to stable/10.

Make sure that the flags for the XPT_DEV_ADVINFO CCB are initialized
properly.
If there is garbage in the flags field, it can sometimes include a
set CDAI_FLAG_STORE flag, which may cause either an error or
perhaps result in overwriting the field that was intended to be
read.
sys/cam/cam_ccb.h:
Add a new flag to the XPT_DEV_ADVINFO CCB, CDAI_FLAG_NONE,
that callers can use to set the flags field when no store
is desired.
sys/cam/scsi/scsi_enc_ses.c:
In ses_setphyspath_callback(), explicitly set the
XPT_DEV_ADVINFO flags to CDAI_FLAG_NONE when fetching the
physical path information. Instead of ORing in the
CDAI_FLAG_STORE flag when storing the physical path, set
the flags field to CDAI_FLAG_STORE.
sys/cam/scsi/scsi_sa.c:
Set the XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE when
fetching extended inquiry information.
sys/cam/scsi/scsi_da.c:
When storing extended READ CAPACITY information, set the
XPT_DEV_ADVINFO flags field to CDAI_FLAG_STORE instead of
ORing it into a field that isn't initialized.
sys/dev/mpr/mpr_sas.c,
sys/dev/mps/mps_sas.c:
When fetching extended READ CAPACITY information, set the
XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE instead of
setting it to 0.
sbin/camcontrol/camcontrol.c:
When fetching a device ID, set the XPT_DEV_ADVINFO flags
field to CDAI_FLAG_NONE instead of 0.
sys/sys/param.h:
Bump __FreeBSD_version to 1100061 for the new XPT_DEV_ADVINFO

For both iSCSI initiator and target increase socket buffer sizes before
establishing connection.
This is a workaround for Chelsio TOE driver, that does not update socket
buffer size in hardware after connection established, and unless that is
done beforehand, kernel code will stuck, attempting to send/receive full
PDU at once.
Use direct hardware access for internal requests for KCS and SMIC. In
particular, updates to the watchdog should no longer sleep.
- Add a new IPMI_IO_LOCK for low-level I/O access. Use this for
kcs_polled_request() and smic_polled_request().
- Add a new backend callback "ipmi_driver_request" to handle a driver
request. The new callback performs the request sychronously for KCS
and SMIC. SSIF still defers the work to the worker thread since the
worker thread sleeps during request processing anyway.
- Allocate driver requests on the stack rather than using malloc().

Moves all the duplicate code to a single function.
Verify for invalid modes and unwanted flags before pass the new flags to
driver.
Make gpio_default_map_gpios() static. No functional changes.
Improves the GPIO API description a little bit.
gpio_pin_max must return the maximum supported pin number and not the total
number of pins on the system.
Remove unnecessary code.
After r273566, the gpiobus version of bus_print_child() also works on FDT
systems.
Fix gpiobus_child_location_str() to return a real string with the mapped
pins.
Make gpiobus_print_pins() static again.
Add basic interrupt management code to gpiobus and ofw_gpiobus.
This is the general support to allow the use of GPIO pins as interrupt
sources for direct gpiobus children.
The use of GPIO pins as generic interrupt sources (for an ethernet driver
for example) will only be possible when arm/intrng is complete. Then, most
of this code will need to be rewritten, but it works for now, is better
than what we have and will allow further developments.
Fix the gpiobus locking by using a more sane model where it isn't necessary
hold the gpiobus lock between the gpio calls.
gpiobus_acquire_lock() now accepts a third parameter which tells gpiobus
what to do when the bus is already busy.
When GPIOBUS_WAIT wait is used, the calling thread will be put to sleep
until the bus became free.
With GPIOBUS_DONTWAIT the calling thread will receive EWOULDBLOCK right
away and then it can act upon.
This fixes the gpioiic(4) locking issues that arises when doing multiple
concurrent access on the bus.
Fix the build of non-FDT systems by moving the gpiobusvar.h header outside
the FDT #ifdef.
While here remove a few unused headers.

- Switching the mode of Ricoh R5CE823 to SD2.0 causes their PCI device ID
to change to 0xe822, which may be persistent across reboots and, thus,
confuse other OSes. Therefore, restore the original mode and frequency

- Report Ricoh R5CE822 as such.
- According to Linux, Ricoh R5CE822 also need SDHCI_QUIRK_LOWER_FREQUENCY.
