The Toshiba parts all have a 24 MHz HCLK, but HTC ASIC3 has a 24.576 MHz HCLK
and AMD Imageon w228x's HCLK is 80 MHz. With this patch, the MFD driver
provides the HCLK frequency to tmio_mmc via mfd_cell->driver_data.

Due to the way that the WM8350 audio driver handles CODEC_ENA many of
the WM8350 audio registers are marked as volatile when they aren't
actually so. Allow the audio driver to see a cache of these values for
inspection during interrupt context.
To do this we need to stop satisfying any bits from volatile registers
from cache - there's no real benefit from doing so anyway, we did the
read already.

Reverse the order of the tests for loop exit so we use a valid value
before we time out. Vanishingly unlikely to happen since we retry for
several times the expected conversion time.

The C99 specification states in section 6.11.5:
The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

This patch makes htc-pasic3 register the DS1WM and LED cell drivers
through the MFD core infrastructure instead of allocating the platform
devices manually. It also calculates the bus_shift parameter from the
memory resource size.

Some I2C controllers have high overheads for setting up I2C operations
which makes the register cache setup on startup excessively slow since
it does a lot of small transactions. Reduce this overhead by doing a
bulk read of the entire register bank and filtering out what we don't
need later.

Add VPLL2 to the set of twl4030-family regulators exposed for
use by various drivers. It's commonly used to power the digital
video outputs (e.g. LCD or DVI displays) on OMAP3 systems.

WARNING: drivers/mfd/built-in.o(.text+0x1706): Section mismatch in
reference from the function sm501_register_gpio() to the function
.devinit.text:sm501_gpio_register_chip()
The function sm501_register_gpio() references
the function __devinit sm501_gpio_register_chip().
This is often because sm501_register_gpio lacks a __devinit
annotation or the annotation of sm501_gpio_register_chip is wrong.

Many ARM platforms do not provide a mach/cpu.h so rather than guarding
the use of that header with CONFIG_ARM guard it with the guards used
when testing for the OMAP variants in the body of the code.
