Looks like the default location for TI firmware is inside the ti-connectivity
directory, to be coherent with other firmware request used by TI drivers, load
the TIInit firmware from this directory instead of /lib/firmware directly.

The tty core provides an interface for flushing the driver's
write buffer: tty_driver_flush_buffer(); prefer the provided
interface over open-coded. Open-coding can lead to errors
such as the duplicated call in the st_kim driver.

This reverts commit eccf2979b2c034b516e01b8a104c3739f7ef07d1.

The reason is that it broke TI WiLink shared transport on Panda.
Also, callback functions should not be added to board files anymore,
so revert to implementing the power functions in the driver itself.

Additionally, changed a variable name ('status' to 'err') so that this
revert compiles properly.

Certain platform specific or Host-WiLink Interface specific actions would be
required to be taken when the chip is being enabled and after the chip is
disabled such as configuration of the mux modes for the GPIO of host connected
to the nshutdown of the chip or relinquishing UART after the chip is disabled.

Similar actions can also be taken when the chip is in deep sleep or when the
chip is awake. Performance enhancements such as configuring the host to run
faster when chip is awake and slower when chip is asleep can also be made
here.

Before the incrementing of ptr in skip_change_remote_baud,
it points to cur_action, but the increment is done by
the size of nxt_action instead. This could cause ptr
to not point to a bts_action structure, which is
harmful for the increment of ptr done in download_firmware.
Therefore, the skipping is first done for cur_action.

However now in case such gpios exist, which requires to be enabled

To fasten the process of firmware download, the chip allows
disabling of the command complete event generation from host.
In these cases, only few very essential commands would have
the command complete events and hence the wait associated with
them.

So now the driver would wait for a command complete event, only
when it comes across a wait event during firmware parsing.
This would also mean we need to skip not just the change baud
rate command but also the wait for it.

The data read will be shared over sysfs entries for the user-space

by opening up the UART, setting the baud-rate and installing the

The architecture of shared transport had begun with individual
protocols like bluetooth, fm and gps telling the shared transport
what sort of protocol they are and then expecting the ST driver
to parse the incoming data from chip and forward data only
relevant to the protocol drivers.

This change would mean each protocol drivers would also send
information to ST driver as to how to intrepret their protocol
data coming out of the chip.

Based on comments from Jiri Slaby, drop the register
storage specifier, remove the unused code, cleanup
the const to non-const type casting.
Also make the line discipline ops structure static, since
its a singleton, unmodified structure which need not be
in heap.

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.
