Hello Andy,
There are two DW DPTX based DisplayPort Controller on rk3588 which
are compliant with the DisplayPort Specification Version 1.4 with
the following features:
* DisplayPort 1.4a
* Main Link: 1/2/4 lanes
* Main Link Support 1.62Gbps, 2.7Gbps, 5.4Gbps and 8.1Gbps
* AUX channel 1Mbps
* Single Stream Transport(SST)
* Multistream Transport (MST)
* Type-C support (alternate mode)
* HDCP 2.2, HDCP 1.3
* Supports up to 8/10 bits per color component
* Supports RBG, YCbCr4:4:4, YCbCr4:2:2, YCbCr4:2:0
* Pixel clock up to 594MHz
* I2S, SPDIF audio interface
The current version of this patch series only supports basic display outputs.
I conducted tests with DP0 in 1080p and 4K@60 YCbCr4:2:0 modes; the ALT/Type-C
mode was tested on Rock 5B
Is there an example of this? I want to implement it for the usb-c port
on the orangepi 5 plus, but I can't quite figure out where I would have
to link the DP output endpoint to?
The usb-c endpoints are all done. Is it to another endpoint in the
usbdp_phy? The only endpoints there seem to be outputs. Or is it
supposed to be left unconnected for the ALT/type-C mode?
I've tried reading through all the relevant dt-bindings but can't find it.
Kind regards,
Maud
