Ensure that the chip is in the lowest power mode possible when suspended
by performing a soft reset on it. On early silicon revisions the lowest
power modes can't be entered without using reset so we can't achieve
equivalent results within the individual drivers.

In OMAP4 Blaze and Panda, 32KHz clock to WLAN is supplied from Phoenix
TWL6030. The 32KHz clock state (ON/OFF) is configured in
CLK32KG_CFG_[GRP, TRANS, STATE] register. This follows the same register
programming model as other regulators in TWL6030. So add CLK32KG as pseudo

This adds a pretty straight-forward system control driver for the
AB8500. This driver will be used from the core platform, e.g the
clock tree implementation in the machine code, and is by nature
singleton.
There are a few simple functions to read, write, set and clear
registers so that the machine code can control its own foundation.

The WM831x interrupt controller provides reporting of the touchscreen
related interrupts in the primary interrupt status register as a
performance optimisation - use this to avoid reading the secondary
status registers for those interrupts.
For code simplicity and to avoid iterating over all interrupts we open

Similar to commit 7e59e097c0, this patch
avoids unnecessary volume control indices for more
Realtek auto-parsers, e g the ALC66x family, on the "Surround" and "Side"

These indices cause these volume controls to be ignored by PulseAudio and
vmaster and should be removed whenever possible.

Previous commit "cfq-iosched: Don't set active queue in preempt" wrongly
cleared stats for preempting queues when it shouldn't have, because when
we choose a queue to preempt, it still isn't necessarily scheduled next.

Section 4.7.3.6 of the ACPI specification requires that the register width

I've stripped the symbols starting with __mod_ as they can have their

possible.

Instead of always creating a huge (268K) deflate_workspace with the
maximum compression parameters (windowBits=15, memLevel=8), allow the
caller to obtain a smaller workspace by specifying smaller parameter
values.
For example, when capturing oops and panic reports to a medium with
limited capacity, such as NVRAM, compression may be the only way to
capture the whole report. In this case, a small workspace (24K works
fine) is a win, whether you allocate the workspace when you need it (i.e.,
during an oops or panic) or at boot time.
I've verified that this patch works with all accepted values of windowBits
(positive and negative), memLevel, and compression level.
