Remove excessive logging from AUX transaction procedures as these
logs amount to log spam while debugging.

to detect hotplug events which involve more than one
sink device.

Update the AUX error codes to match the I2C error codes so that
the driver has the correct corresponding error code. This is
useful for debugging problems in which there is an AUX
transaction failure.

Add support to enter failsafe mode on EDID read failures
that might be caused by corrupt EDID blocks or AUX
transaction failures. The failsafe mode for this driver
is 640x480 at 60fps, in accordance with the Display Port
v1.3 specification.

Add support to parse the test request vector to determine
whether an automated EDID test has been requested. If requested,
send the checksum found in the first EDID block back to the sink
for validation.

Add support for a new 1080p configuration which utilizes 4 lanes
at a link rate of 2.7 GBps. This configuration is added to the
existing table that stores the transfer unit values for
different link and resolution combinations.

Fix the GPIO settings by changing output of GPIO78 to 0 to flip
the on board AUX switch, and furthermore, setting the function
of GPIO38 to gpio. These updated GPIO settings enable flip plug
orientation to work by fixing the AUX switch and the PHY lane
configuration.

Fix the PHY programming sequence for flip plug orientation by
ensuring that the correct PHY_MODE and LANE_MODE values are
selected, depending on the orientation and link rate
respectively.

In existing HDMI PLL driver the VCO frequency value is truncated
so following PLL calculation could be impacted. Use 64 bit value
instead to maintain the necessary precision.

Clock recovery and dynamic resolution change require changing
HDMI clock rate while HDMI PLL is on. There are two paths while
clock is changed, one is atomic update which doesn't require
PLL tear down, the other is when clock rate change is too big
and a full PLL tear down is needed.

Commit 18cd808986ba101d ("usb: dwc3-msm: Make power collapse
and power-on-reset mandatory") removed the device tree properties
for power-collapse due to which the dwc3_restart_usb_work() which
was supposed to do a full POR sequence by simulating a cable
disconnection-reconnection sequence now only does a dbm reset.
Fix this, so that dwc3_restart_usb_work(), does a full POR.
