If suppose the UIM were to die and hence UART were to close when the
Bluetooth/FM or GPS is turned on, prep the ST for a state where-in if
the UIM comes back up, Bluetooth/FM/GPS can be turned on.

If during validation of the firmware download the data doesn't match what is
expected out of the chip, this calls for a firmware download failure and a
retry.
Free the SKB which collects response during such scenarios.

When the line discipline install fails for reasons such as missing user-space
UIM or broken communication between UIM and ST driver, then the ST
attempts/retries to request for ldisc installation again.

download firmware behaves differently at different times, when logs are
enabled and the system is loaded, the wait_for_completion is able to wait for
every send, However during other times the wait does not happen.
So, for reliability reinitializing the completion before every send, makes
sure the wait happens for every send.

Texas Instrument's shared transport driver interpret incoming data from the
UART based on the various protocol drivers registered to the driver such as
btwilink driver or FM or GPS driver which provide logical channel IDs.
In case of bad-behavior from chip such as HCI Event response for a GPS command
or a HCI Event (h/w error event) for a FM response & In case of bad-behavior
from UART driver such as dropping data bytes a fail-safe is required to avoid
kernel panic.

After the version information has been read, the completion which assists in
wait_for_completion during the firmware send/wait sequence is being re-used
and hence this needs to be re-initialised for fool proof firmware download
retries.

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.

Previously the private data of each protocol registered to use ST was
used to determine whether the protocol was registered to use shared
transport or otherwise.
However, now a flag is_registered is maintained to identify whether a
protocol intends to use ST.
Upon closing of the UART the error message relevant to this lack of
un-registration was misleading and this patch fixes that.

Did this as a merge because of (trivial) conflicts in
- Documentation/feature-removal-schedule.txt
- arch/xtensa/include/asm/uaccess.h
that were just easier to fix up in the merge than in the patch series.
Both displays on digsy_mtc board obtain their configuration from microwire
EEPROMs which are connected to the SoC over GPIO lines. We need an easy
way to access the EEPROMs to write the needed display configuration or to
read out the currently programmed configuration. The generic
eeprom_93xx46 SPI driver added by previous patch allows EEPROM access over
sysfs. Using the simple driver added by this patch we provide used GPIO
interface and access control description on the board for generic
eeprom_93xx46 driver and spi_gpio driver.

As stated in drivers/mfd/cs5535-mfd.c, the mfd driver exposes the BARs
which then make the GPIO, MFGPT, ACPI, etc. all visible to the system.
So the dependencies of the MFGPT stuff have changed, and most people
expect Kconfig to bring in the necessary dependencies. Without them, the
module fails to load and most people don't understand why because the
details of the rewrite aren't captured anywhere most people who know to
look.
This dependency needs to be reflected in Kconfig.
