In addition, write the correct segment address when reading more than two extension blocks.

The transaction retry strategy is as follows: first repeat the transaction using the same PHY AUX settings, and then retry the transaction using updated PHY AUX settings if repeating the transaction has failed.

Handle this by checking for a change in downstream sink count and appropriately handling EDID reads. It is also possible that the branch device may not have any local EDID. In such cases, when the downstream sink count is zero, do not read EDID.

For example, the driver must indefinitely postpone the handling of other events from the sink until the power off event is complete, ensuring that there is no interleaving of events that could lead to a bad state, or un-clocked register access.

While calulcating the total fetch pixels decimation calculation should be applied after adding the fetch values to the src rect. This change corrects this calculation and typecasts fetch values to signed 8 bit integer. There is no need to consider repeat values since repeat values are set to 0 by libscaler.

The current implementation sends the AUX command to specify the reduced bandwidth but doesn't actually reduce the link rate. This causes link training failures during compliance testing. Add change to disable the DP mainlink clocks and re-enable them with reduced rate in such cases.

For example, in case of framework restart, both display and audio HALs are not available, so nobody will notify and unblock hpd call. Another case is continuous splash in which unblank is delayed till the first display kickoff, so hpd cannot blocking wait for such a late notification.

The maximum value that can be specified for this field is 4095. In certain instances, a sink may list a resolution with 4096 horizontal addressable video pixels in the DTD by listing a value of 4095. If this value is parsed as is, it can lead to incorrect behavior. Fix this by explicitly updating the value to 4096.
