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.
