There is a possibility of unacknowledged pending interrupt at the time
of secondary event ring cleanup. As a result xHC does not generate any
interrupt further because event handler busy flag is set. Hence disable
interrupter to prevent any further interrupt, acknowledge any pending
interrupt and clear event handler busy flag. This allows xHC to generate
interrupt after setting up new event ring.

Add vdd_class support which would help vote/unvote for any voltage rail
for the clock frequency to the regulator framework. A clock client request
for a clock frequency would look for the corresponding voltage vote and
would be send the request to regulator framework.

Only call an SVID handler's disconnect function only if it was
previously connected, i.e. when the state machine had proceeded
received a successful DISCOVER_SVIDs response. This helps to
avoid excessive notification to SVID clients.
While at it, require that .connect and .disconnect callbacks
are supplied during registration. This helps to eliminate NULL
checks each time they are called.

The codec DSP needs to be enabled only when there is use case that
utilizes the DSP. This way the codec DSP can be shutdown when it
is not used. Change adds misc device node that the user space can
use to trigger boot and shutdown of DSP.

Upon host bus reset driver draws 0mA and switches
to higher value 900/500 mA after moving to configured
state. This causes a glitch in the led and battery icon
status. Hence request to draw 100mA to void the glitch.

Audio format received from QMI client are not one to one
mapped to pcm format defined by ALSA driver. This causes
format mismatch when QMI client request a format not
defined by ALSA driver. Fix this by creating a mapping
between two formats.

This commit provides a mechanism for the host drivers to advertise the
support for different beacon intervals among the respective interface
combinations in a group, through NL80211_IFACE_COMB_BI_MIN_GCD (u32).
This value will be compared against GCD of all beaconing interfaces of
matching combinations.
If the driver doesn't advertise this value, the old behaviour where
all beacon intervals must be identical is retained.
If it is specified, then any beacon interval for an interface in the
interface combination as well as the GCD of all active beacon intervals
in the combination must be greater or equal to this value.
