This is the base EC implementation, which provides a high level
interface to the EC for use by the rest of the kernel. The actual

registers itself with this interface.
Interrupts are passed on through a notifier.
A simple message structure is used to pass messages to the

extcon: arizona: Updates for v3.10
There's a bunch of different things in this series, I can split them out
if need be:
- Support for configuring the button detection circuit to reflect the
accessories supplied with the system.
- Improvements in the HPDET based detection scheme.
- Additional robustness against more pathological use cases.
- A few small standalone fixes.
The pm8921 driver has been broken for a while now, but was prevented
from compiling because the SSBI bus driver was missing. Now that SSBI
is present, pm8921 causes compile fails.
Until the pm8921 driver is fixed, mark it as BROKEN to prevent
compiles from failing.

Although the SSBI sub is currently only used on MSM SoCs, it is still
a bus in its own right. Remove this msm_ prefix from the driver and
it's symbols. Clients can now refer directly to ssbi_write() and

place as it is now, but now we get a gcc warning about an unused function.
In order for the twl4030_madc_remove to work correctly in built-in code, we

Currently driver sets the irq type to IRQF_TRIGGER_LOW which is

[ 0.208513] dummy 0-0059: Failed to request IRQ 118: -22
Provide the irq flags through platform data if device is registered
through board file or get the irq type from DT node property in place
of hardcoding the irq flag in driver to support multiple platforms.
Also configure the device to generate the interrupt signal according to
flag type.

As I am working on SPARSE_IRQ a number of implicit resource
grabs in the kernel become evident. For example, some includes
like <linux/irqs.h> would implicitly include <mach/irqs.h>
and then from there <mach/db8500-regs.h>.
In many cases it is masking the fact that drivers do not
properly use resources to pass their dependencies, base
addresses etc. So write explicit #include statements with
TODO items to have this fixed the proper way to all drivers
doing this.
