Resolutions listed in the Detailed Timing Descriptor (DTD) have
detailed information about all the timings. Current implementation
attempts to match the parsed resolution with the resolution database
based on just the Video Information Code (VIC). This can potentially
overlook mismatches in certain parameters such as refresh rates and
can cause unintended results. Fix this by always adding the resolutions
parsed from the DTDs to the reserved timing list.

Current implementation of the EDID parser always ensures that
VGA resolution (640x480) is added to the list of supported modes.
However, this should really be done by the client of the parser
based on their policies. This will avoid usecases where the EDID
parser would report the VGA resolution as supported even if it
was not listed in the sink's EDID.

Current implementation utilizes a simple event queue to handle
some of the tasks when setting up or tearing down a display port
session. This is currently achieved using a workqueue and assumes
that there can be at most one unhandled event outstanding. This
may not be valid and can result certain events being skipped.
Refactor this by handling the events in a new event thread.

EDID parser assigns temporary Video Identification Codes (VIC) for
all non-standard resolutions when parsing a sink's EDID. These
VICs can be reused for a subsequent connection for different
resolutions. In the current implementation of the Display Port (DP)
driver, a resolution change is detected whenever a new VIC is used.
However, when switching between two non-standard resolutions spanning
connections to two different sinks, it is possible to have the same
VIC assigned for the two resolutions. This can result in abnormal
behavior. Fix this by resetting the video identification code and panel
information to reset value every time we get an HPD for disconnect.

During authentication, HDCP may poll hardware for status.
HDCP may be turned off by other thread abruptly depending
on the use-case. Do not poll hardware in case HDCP has been
turned off. Also, wait for authenticating thread to finish
in hdcp off thread to avoid any race condition.

Interrupts from sinks (cp_irq) may come asynchronously at different
states for HDCP authentications. In case HDCP has failed and an
interrupt is received from sink, do not process it to avoid getting
unnecessary failures.

If read function is waiting for interrupt and after that
NFCC goes to recovery, MW will call ioctl (0) and ioctl (1),
In ioctl (0) call we are disabling interrupt so read function
was waiting for interrupt and ioctl call has disabled interrupt,
now there is no possibility interrupt will be enabled again
because only read function enables the interrupt.
Enabled interrupt in ioctl (1) so that we can receive data
after reset/recovery.
