can be correctly programmed with link pattern and drive
settings.

Add table to store transfer unit settings for different
resolutions. The table is used for mapping the resolution
with the lane count and Display-port link rate.

Limit the resolutions provided by sink to the ones supported
by the interface so that user modules do not receive the resolutions
which are not supported by the interface.

Add new settings for link-training parameters. Add
code in DP OFF to set the DP state to IDLE mode.
Add support for DP global reset before
initializing DP controller.

Add changes to have default settings for color depth and
output format in DP controller.
Currently, the workqueue used to handle different events
in controller driver has very high delay in handling events.
Fix this.

Use the information about lane count and orientation
provided in the spare MDP registers by the DP controller
driver to configure the PLL lock sequence.

The DisplayPort PHY driver needs information about the number
of lanes and the plug orientation to do additional settings.
Add code to support this.

First update the audio switch node to indicate that the cable was
disconnected. Wait for the audio codec to indicate that the teardown
of the audio path has been completed, timing out after three
seconds. This ensures that the audio framework will start and end
the audio teardown while the interface VSync is still running,
ensuring a graceful shutdown of the audio path.

Before going for full PLL enable sequence, we need to clear out the
override bit and precalibrated values of VCO_TUNE and KVCO_CODE, as
these registers might be storing values for old VCO rate. This will
cause the DSI PLL to be in a bad state and hence PLL unlock errors
might occur during use case like resolution switch. So always clear
the precalibrated values first in PLL configuration sequence.

Currently mtp function driver is skipping function
setup call back by not populating function pointer
in function instance. Also, is_ptp flag is set
incorrectly as true for mtp instance which would
pass wrong os descriptor for mtp and ptp instance.
Allow mtp driver to send os descriptor by populating
function pointer in function instance and correctly
set the is_ptp flag to pass valid os descriptors.

Consider recent history (residencies) of the low power modes per
core while the next low power mode to enter is selected. If most
of the history says the pattern of residencies is repeating with
minimal deviation then use the average of these for predicting
the next mode to enter.
If the pattern is not repeating then if more than 50 percent of
the samples out of history have exited a low power mode earlier
than the minumim residency of that mode, restrict it and also low
power modes deeper than that.
In any of the above case, trigger a hrtimer to wakeup cpu with
timeout as predicted+delta or max residency of the mode selected
if a deeper state can be selected after waking up incase if
prediction goes wrong.
