This patch series adds a new compatible for the Display SubSystem (DSS) controller on TI's AM62A7 SoC. It further adds the required support, for the same, in the tidss driver. The DSS controller is similar to the recently added AM625 DSS, with the key difference being the absence of VP1 output on the SoC. The VP1 in AM62A7 DSS is tied off and cannot be used, unlike in AM625, where the VP1 was connected to 2 OLDI TXes. The video pipeline that corresponds to VP1 still exists and can be used to overlay planes on the VP2's primary plane. This can be done using the overlay managers inside the SoC. Moreover, DSS VP2 can output Full-HD RGB888 DPI video signals. I have tested these patches on AM62A7 SK-EVM, which converts DPI signals to HDMI on the platform using the Sil9022A HDMI transmitter. All the patches, required to enable display on AM62A7-SK, can be found on my github fork[0] in the branch "next_am62a-v3".
