Subject: [PATCH v2 8/9] media: dt-bindings: Add Intel Displayport RX IP
Date: Wed, 21 Feb 2024 16:02:14 +0000 [thread overview]
Message-ID: <20240221160215.484151-9-panikiel@google.com> (raw)
In-Reply-To: <20240221160215.484151-1-panikiel@google.com>
The Intel Displayport RX IP is a part of the DisplayPort Intel FPGA IP
Core. It implements a DisplayPort 1.4 receiver capable of HBR3 video
capture and Multi-Stream Transport. The user guide can be found here:

+description: |
+ The Intel Displayport RX IP is a part of the DisplayPort Intel FPGA IP
+ Core. It implements a DisplayPort 1.4 receiver capable of HBR3 video
+ capture and Multi-Stream Transport.
+
+ The IP features a large number of configuration parameters, found at:
+ https://www.intel.com/content/www/us/en/docs/programmable/683273/23-3-20-0-1/sink-parameters.html
+
+ The following parameters have to be enabled:
+ - Support DisplayPort sink
+ - Enable GPU control
+ The following parameters' values have to be set in the devicetree:
+ - RX maximum link rate
+ - Maximum lane count
+ - Support MST
+ - Max stream count (only if Support MST is enabled)
