Enable eMMC background operations (BKOPS) feature.
If URGENT_BKOPS is set after a response, note that BKOPS are required.
Immediately run BKOPS if required. Read/write operations should be
requested during BKOPS(LEVEL-1), then issue HPI to interrupt the
ongoing BKOPS and service the foreground operation.
(This patch only controls the LEVEL2/3.)
When repeating the writing 1GB data, at a certain time, performance is
decreased. At that time, card triggers the Level-3 or Level-2. After
running bkops, performance is recovered.
Future considerations:
* Check BKOPS_LEVEL=1 and start BKOPS in a preventive manner.
* Interrupt ongoing BKOPS before powering off the card.
* How do we get BKOPS_STATUS value (periodically send ext_csd command)?
* If using periodic bkops, also consider runtime_pm control.

low power mode changes are causing issues like,delay in reponse to
touch , and controller is not recognizing the touch events as its
scan rate is also low in low power mode state . since controller is
not recognizing the touch in low power mode state , so only way
for the controller to come out of low power mode is to do multi-touch
and controller responds randomly to one of the touches and comes out
of the low power mode.

The demux is an in-kernel software component whose purpose is to take
an incoming TSIF stream and split it into multiple output channels
based on the PID field in each TS packet. Each output channel can be
used for a different purpose, such as audio, video or channel
information. In order to get good performance when moving such large
data streams around, the demux was placed in kernel-space as to
prevent copying memory buffers between kernel-space and user-space, at
least at this early stage in processing the traffic. Originally the
design of the TSPP driver was based on the earlier TSIF driver, so it
contained only a user-space API.

Add version check to allow VADC/IADC reads if the

who need to know if the ADC driver is ready. There is a
bug where the completion is not initialized. Fix it

conversion.
Add scaling functions to support reading the die temperature,
XO_THERM, batt_therm and batt_id. Add the ratiometric
calibration routine that uses the vref/gnd for calibration.
The ratiometric calibration is used for calibrating xo_therm,

This change addresses following enhancements to debug
logging:-
1) Add data payload logging which is not currently
supported. This helps to sniff first 32 bytes of data
being sent and received. Data payload logging is
enabled by default. To disable data payload logging:-
echo 0 > /sys/module/ehci_hcd/parameters/enable_payload_log
2) Current urb submission event logging does not cover
root hub submissions, hence move urb submission logging
to hcd driver.
3) Current urb submission event logging does not return
the correct status if submission fails. Hence log the
return status of urb submission.

Data contact detection (DCD) involves applying small amount of current on
D+ and waiting for it to go low. The D+ is pulled to low when the data
pins get contacted with the other device data pins.
The current code does not disable D+ pull-down resistor during DCD. If this
resistor is not disabled, the current applied on D+ becomes low immediately
even without connecting to any device. Fix it. Remove enable_dcd flag
from platform data as data contact detection is working reliably on all
targets supported by this driver.

controller will issue interrupts to processor. Increasing
this value results in fewer interrupts which may save power
as processor has to handle fewer interrupts. Side effect of
increasing this value is higher data latency. For fusion3,

for other targets. Also, allow ehci stack to set ITC value
