After opening and closing the file /dev/ipoctal.X.Y.Z for the second time, it
gives a kernel oops due to a dereference of a NULL pointer.

The problem was that tty->driver_data was not properly initialized when
accessing the file for the second time.

The macros 'update_dacsr', 'update_adcsr', and 'update_supcsr' all use
the 'devpriv' macro which uses a local variable of a specific name and
yeilds a pointer derived from that name. They are also just wrappers
around simple 'outw' calls. Remove the macros.

This patch has the common thermal framework support for OMAP
bandgap driver. It includes the zone registration and unregistration,
the cpu cooling and the trip definitions.

The trips definition is essentially one trip for passive cooling
using the generic cpu cooling device and another one for thermal
shutdown. The cpu cooling device is built based on the existing
cpu freq table. The build should be agnostic to omap version,
but relies that cpufreq is up and running by the time the driver
registers the cpu cooling, as it relies on the table walk api
from cpufreq.

In the System Control Module, OMAP supplies a voltage reference
and a temperature sensor feature that are gathered in the band
gap voltage and temperature sensor (VBGAPTS) module. The band
gap provides current and voltage reference for its internal
circuits and other analog IP blocks. The analog-to-digital
converter (ADC) produces an output value that is proportional
to the silicon temperature.

This patch provides a platform driver which expose this feature.
It is moduled as a MFD child of the System Control Module core
MFD driver.

This driver provides only APIs to access the device properties,
like temperature, thresholds and update rate.
