After part I authentication, SW DDC is not disabled and because of
this, we observe arbitration issues during part III authentication.
Disable SW DDC before starting part III of HDCP authentication.
Fail part II of authentication with repeater if its device count is zero.

Display Port driver never supported YC420 formats.
Also w.r.t to display quality, 4K30 RGB 8bit is
better than 4K60 YC420 8bit.
So, do not include edid modes(VICs) from YC420 Video
Data Block while parsing EDID.

Clear PP features dirty flags only when they are programmed, based on
programming stage, i.e. clear dirty flags of features programmed in
early stage after early stage programming and clear dirty flags of
features programmed in deferred stage after their actual programming
is complete.
Clearing the flags in one go is resulting in missing programming of
features designated to be programmed in early stage, if the dirty flags
are updated in between the stages.

The SD card specification allows cards to error out a SWITCH command
where the requested function in a group is not supported. The spec
provides for a set of capabilities which indicate which functions are
supported.
In the case of the power limit, requesting an unsupported power level
via the SWITCH command fails, resulting in the power level remaining at
the power-on default of 0.72W, even though the host and card may support
higher powers levels.
This has been seen with SanDisk 8GB cards, which support the default
0.72W and 1.44W (200mA and 400mA) in combination with an iMX6 host,
supporting up to 2.88W (800mA). This currently causes us to try to set
a power limit function value of '3' (2.88W) which the card errors out
on, and thereby causes the power level to remain at 0.72W rather than
the desired 1.44W.
Arrange to limit the selected current limit by the capabilities reported
by the card to avoid the SWITCH command failing. Select the highest
current limit that the host and card combination support.
