Rob Herring 5be478f9c2 dt-bindings: Another round of adding missing 'additionalProperties'
Another round of wack-a-mole. The json-schema default is additional
unknown properties are allowed, but for DT all properties should be
defined.

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.
