+description: |
- The IT6505 is a high-performance DisplayPort 1.1a transmitter,
- fully compliant with DisplayPort 1.1a, HDCP 1.3 specifications.
- The IT6505 supports color depth of up to 36 bits (12 bits/color)
- and ensures robust transmission of high-quality uncompressed video
- content, along with uncompressed and compressed digital audio content.
- Aside from the various video output formats supported, the IT6505
- also encodes and transmits up to 8 channels of I2S digital audio,
- with sampling rate up to 192kHz and sample size up to 24 bits.
- In addition, an S/PDIF input port takes in compressed audio of up to
- 192kHz frame rate.
- Each IT6505 chip comes preprogrammed with an unique HDCP key,
- in compliance with the HDCP 1.3 standard so as to provide secure
- transmission of high-definition content. Users of the IT6505 need not
- purchase any HDCP keys or ROMs.

Drop this. You should be using the usb-connector binding instead which means you should have a OF graph port to the connector. For TypeC, there's a defined port for DP.
