Also flips the switch on only setting up the rf associate sysfs
attr only if we think we're looking at an RF device, vs. previously,
setting up the attr for all 0xffdc devices, so its possible (but a bit
unlikely) there's another iMON RF device we'll have to fix up.

IR support on FusionHDTV cards is broken since kernel 2.6.31. One side
effect of the switch to the standard binding model for IR I2C devices
was to let i2c-core do the probing instead of the ir-kbd-i2c driver.
There is a slight difference between the two probe methods: i2c-core
uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As
some IR I2C devices only support reads, the new probe method fails to
detect them.
For now, revert to letting the driver do the probe, using 0-byte
reads. In the future, i2c-core will be extended to let callers of
i2c_new_probed_device() provide a custom probing function.

pvrusb2: Delete sysfs class device as the _very_ last step, after
we're sure that all driver contexts have gone away first. This is
important because it appears that there isn't any protection from a
struct device instance reference a deleted struct class instance. The
assumption in the kernel code appears to be that the class instance is
assumed to be around for the life of the device. So we can't let the
class instance go away until all referencing device instances are
gone; this is ensured by delaying removal of the class instance until
after the driver contexts have all gone away. This bug has been
present for a very long time but it didn't apparently become malignant
until recently (probably because of other changes in the kernel).

This patch fixes an occasional transmit lockup in the mac-fcc which
occurs after a tx error. The test scenario had the local port set
to autoneg and the other end fixed at 100FD, resulting in a large
number of late collisions.
According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after
a tx error occurs, TBPTR may sometimes point beyond BDs still marked
as ready. This patch walks back through the BDs and points TBPTR to
the earliest one marked as ready.

There still is a race that may result in suspending the system in
the middle of an EC transaction in progress, which leads to problems
(like the kernel thinking that the ACPI global lock is held during
resume while in fact it's not).
To remove the race condition, modify the ACPI platform suspend and
hibernate callbacks so that EC transactions are blocked right after
executing the _PTS global control method and are allowed to happen
again right after the low-level wakeup.
Introduce acpi_pm_freeze() that will disable GPEs, wait until the
event queues are empty and block EC transactions. Use it wherever
GPEs are disabled in preparation for switching local interrupts off.
Introduce acpi_pm_thaw() that will allow EC transactions to happen
again and enable runtime GPEs. Use it to balance acpi_pm_freeze()
wherever necessary.
In addition to that use acpi_ec_resume_transactions_early() to
unblock EC transactions as early as reasonably possible during
resume. Also unblock EC transactions in acpi_hibernation_finish()
and in the analogous suspend routine to make sure that the EC
transactions are enabled in all error paths.

acpi pad driver kind of aggressively marks TSC as unstable at init
time, on mwait capable and non X86_FEATURE_NONSTOP_TSC systems. This is
irrespective of whether pad driver is ever going to be used on the
system or deep C-states are supported/used. This will affect every user
who just happens to compile in (or get a kernel version which
compiles in) acpi pad driver.
Move mark_tsc_unstable() out of init to the actual idle invocation path
of the pad driver.
There is also another bug/missing_feature in the code that it does not
support 'always running apic timer' and switches to broadcast mode
unconditionally. Shaohua, can you take a look at that please.

This EXPERIMENTAL driver supersedes acpi_idle on
Intel Atom Processors, Intel Core i3/i5/i7 Processors
and associated Intel Xeon processors.
It does not support the Intel Core2 processor or earlier.
For kernels configured with ACPI, CONFIG_INTEL_IDLE=y
allows intel_idle to probe before the ACPI processor driver.
Booting with "intel_idle.max_cstate=0" disables intel_idle
and the system will fall back on ACPI's "acpi_idle".
Typical Linux distributions load ACPI processor module early,
making CONFIG_INTEL_IDLE=m not easily useful on ACPI platforms.
intel_idle probes all processors at module_init time.
Processors that are hot-added later will be limited
to using C1 in idle.

commit d306ebc286
(ACPI: Be in TS_POLLING state during mwait based C-state entry)
fixed an important power & performance issue where ACPI c2 and c3 C-states
were clearing TS_POLLING even when using MWAIT (ACPI_STATE_FFH).
That bug had been causing us to receive redundant scheduling interrups
when we had already been woken up by MONITOR/MWAIT.
Following up on that...
In the MWAIT case, we don't have to subsequently
check need_resched(), as that c heck was there
for the TS_POLLING-clearing case.
Note that not only does the cpuidle calling function
already check need_resched() before calling us, the
low-level entry into monitor/mwait calls it twice --
guaranteeing that a write to the trigger address
can not go un-noticed.
Also, in this case, we don't have to set TS_POLLING
when we wake, because we never cleared it.

found in the ST-Ericsson U300 platforms. This driver
is a singleton proxy for all access to the AB3550 sub

RTC, regulators, battery and system power control, vibrator,

The interface for the AB3100 is changed to make way for the
ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson
Analog Baseband chips. The register access functions are moved
out to a separate struct abx500_ops. In this way the interface
is moved from the implementation and the sub functionality drivers
can keep their interface intact when chip infrastructure and
communication mechanisms changes. We also define the AB3550
device IDs and the AB3550 platform data struct and convert
the catenated 32bit event to an array of 3 x 8bits.

There're two IRQ pins output from MAX8925. One is PMIC interrupt, the other
is TSC interrupt. But they're sharing one irq chip.
After initializing MAX8925 interrupts, unexpected TSC interrupt may occur and
it can't be cleared if touch driver isn't loaded.
Now move the operation of masking TSC interrupt behind requesting PMIC
interrupt. If touch driver isn't loaded, this interrupt is always masked.

The charger interrupts on the WM831x are unconditionally a wake source
for the system. If the power driver is not able to monitor them (for
example, due to the IRQ line not having been wired up on the system)
then any charger interrupt will prevent the system suspending for any
meaningful amount of time since nothing will ack them.
Avoid this issue by manually acknowledging these interrupts when we
suspend the WM831x core device if they are masked. If software is
actually using the interrupts then they will be unmasked and this
change will have no effect.

Ensure that the hardware has interrupts masked if we are not using
the interrupt controller on the WM831x by initialising the masks
before we check for the setup data required for the IRQ line. This
avoids signalling an unused IRQ line and improves the robustness

Currently completion of WM831x AUXADC conversions is monitored by
checking for convertor enable. Due to the mechanism used to ensure
data corruption is avoided when reading AUXADC data there may under
heavy I/O be a window where this bit has cleared but the conversion
results have not been updated. Data availability is only guaranteed
after the AUXADC data interrupt has been asserted.
Avoid this by always using the interrupt to detect completion. If the
chip IRQ is not set up then we poll the IRQ status register for up to
5ms. If it is set up then we rely on the data done interrupt with a
vastly increased timeout, failing the conversion if the interrupt is
not generated.
This also saves a register read when using interrupts.

Driver for the TI TMP102.
The TI TMP102 is similar to the LM75. It differs from the LM75 by
having a 16-bit conf register and the temp registers have a minimum
resolution of 12 bits; the extended conf register can select 13-bit
resolution (which this driver does) and also change the update rate
(which this driver currently doesn't use).
