This is a re-write of the Motorola mdm6600_modem driver.
The usb_serial_generic_* handlers actually cover the USB bulk to serial data
path. So that code disappears.
The USB interrupt data to TIOCMGET ioctl path does not appear to be used by
pppd in userspace, using a temporary BUG_ON() to confirm.
So we end up with very little but a hook to register generic usb-serial
handlers for the MDM6600 vendor id.
I have not spent time testing behavior in low-power-modes, it is likely I will
need to over-ride some of the generic handlers at that point.

Instead just allow userspace to turn on and off the backlight when
entering suspend. Otherwise we get a race condition on some hardware
where the backlight does not go off.

Disable cpcap interrupts at suspend and re-enable at resume, to avoid

This allow's Motorola's mdm6600_modem driver to work with suspend.
Patch provided by Motorola.
mdm6600_modem will shortly be replaced by a re-write, but its useful to commit
this update for easier A/B testing.

If Stingray is powered up with a charger already attached, the battery
driver would not report charging to the system, even though the battery
was being charged. This charges the DS2781 battery driver to check
if a charger is already present when the driver is probed.

due to the incorrect value being used for Rsnsp. The DS2781 has
a register with the correct value, so use it instead of a hard

This change will add the file cpcap-irq to the debug fs directory. The file will
provide data for each of the cpcap interrupts. The data includes the interrupt
name, if the interrupt is enabled/disabled, if a handler has been registered
with the interrupt, and the number of times the interrupt has been generated.

Previously, Message Processor always generated
CRC byte at end of message.
Now(version 8), this CRC byte is generated only upon request.
To request that a checksum is generated, the MSBit
of the address of the Message Processor object is set to 1.
By default the CRC byte is not generated, reading the CRC byte
will remove new messages from IC causing lost touches.
Added control flag and message size correction for this feature.
