move the 3 source files st_core.c, st_kim.c and st_ll.c
from staging to drivers/misc/.
Texas Instrument's WiLink 7 chipset packs wireless technologies like
Bluetooth, FM, GPS and WLAN into a single die.
Among these the Bluetooth, FM Rx/Tx and GPS are interfaced to a apps processor
over a single UART.
This line discipline driver allows various protocol drivers such as Bluetooth
BlueZ driver, FM V4L2 driver and GPS simple character device driver
to communicate with its relevant core in the chip.
Each protocol or technologies use a logical channel to communicate with chip.
Bluetooth uses the HCI-H4 [channels 1-4], FM uses a CH-8 and
GPS a CH-9 protocol. The driver also constitutes the TI HCI-LL Power
Management protocol which use channels 30-33.

Move the header to a standard linux device driver location.
This should pave the way for other drivers to be moved into the relevant
directories.
ti_wilink_st.h is a common header file used by the TI's shared transport device
driver for WiLink chipsets. Each individual protocol drivers like bluetooth
driver, FM V4L2 driver and GPS drivers will make use of this header.

move all the header information to ti_wilink_st.h.
This header would then not only serve the local modules like the st_core.c,
st_kim.c and st_ll.c but also the external modules/protocol drivers that are
dependent on the shared transport driver.
Modify the source files to include the new header ti_wilink_st.h,

Platform devices tend to have id as -1 when only 1 device exist and
a value >=0 when multiple devices exist, since we plan to store all
these platform devices if multiple exist, there was a requirement to
have id to be >=0.
The patch fixes this problem.

In order to support multiple ST platform devices, a new symbol
'st_get_plat_device' earlier needed to be exported by the arch/XX/brd-XX.c
file which intends to add the ST platform device.
On removing this dependency, now inside ST driver maintain the array of
ST platform devices that would be registered.
As of now let id=0, as and when we end up having such platforms
where mutliple ST devices can exist, id would come from
protocol drivers (BT, FM and GPS) as to on which platform device
they want to register to.

When the chip is in use, information like the chip's ROM version and the
protocols currently making use of the chip needs to be made known to
user-space.
Earlier the version and the protocol-list were exposed as sysfs entries
now cleanup by making them as debugfs entries, also in process remove
any unwanted/previously unused sysfs entries.

Replace looping on the data buffers and printk-ing by
print_hex_dump.
Also replace most of the pr_info by pr_debug to reduce logging at
default loglevels (7 in our case..)

Providing a context which can be passed around the driver, the KIM's platform
driver's struct device to be used to dev_set_drvdata and dev_get_drvdata.
The ST core's data is passed around using tty's disc_data and in other
cases the ST KIM's platform device is exposed from the board-XX.c which
adds KIM platform device whose dev is used.
Thereby remove the need for the global reference struct kim_data_s *kim_gdata;

Remove the older way of communicating with user-space
daemon UIM.
The older way involved creating of a new kobj and pid
sysfs file under it, and sending signal using that pid.
Now we communicate via rfkill to user-space UIM.
Background: UIM is the user-space daemon which upon
notification from ldisc driver, opens the tty, sets
default baud and then installs (tiocsetd) the ldisc.

Kernel Space Init-Manager works along with User-Mode
Init Manager daemon running to maintain the UART state.
Communication between user-space daemon and this module can be
1. Via the pid written onto sysfs entry
2. Via the rfkill subsystem
It also is a platform driver with a relevant platform device
in the board-*.c along with the list of BT/FM/GPS chip enable
gpio configuration
