Incorrect Support of Address-Only AUX I2C Requests in DisplayPort Transmitter

Description

The DisplayPort IP core transmitter incorrectly generates AUX I2C address-only transactions.

This issue may cause the EDID read and all I2C address-only AUX transactions to fail.

Resolution

To avoid this issue, don’t use address-only AUX I2C transactions.

This issue is fixed in version 14.1 of the DisplayPort IP core.
