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
of checks that the IRQ is in use.

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.

The Janz VMOD-TTL is a MODULbus daughterboard which fits onto any MODULbus

Z8536 CIO Counter/Timer and Parallel IO Unit.

The board must be physically configured with jumpers to enable a user to
drive output signals. I am only interested in outputs, so I have made this

reference from the function pm860x_device_exit() to the function
.devexit.text:device_irq_exit()
The function pm860x_device_exit() references a function in an exit

Often the function device_irq_exit() has valid usage outside the exit

This is often because pm860x_device_init lacks a __devinit

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).

The Apple SMC uses a systematic labeling scheme for the hardware
temperature sensors. This scheme is currently hidden from
userland. Since the sensor set, and consequently the numbering,
differs between models, an extensive database of configurations is
required for an application such as fan control. This patch adds the
SMC labels to the hwmon sysfs interface, allowing applications to use
the sensors more intelligibly.
