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

Description

When the GPU is used, the DisplayPort IP core receiver incorrectly handles the DisplayPort source’s 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 from the DisplayPort source.

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