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 in 1080p and 4K@60 YCbCr4:2:0 modes; the ALT/Type-C mode
hasn't been tested yet, but I suspect it will likely work. HDCP and audio
features remain unimplemented. For RK3588, it's only support SST, while in
the upcoming RK3576, it can support MST output.

Andy,

Is tis series enough to get usbc1/dp1 working as video output ?
(assuming i will add necessary code in dt) 

rock5-itx has second hdmi port using usbc1/dp1 lanes 2,3 to ra620 dp->hdmi converter

is it worth to play with this or it is too early?
