This patch series adds a new compatible for the Display SubSyetem controller on TI's AM625 SoC. It further adds the required support for the same in the tidss driver. The AM625-DSS is a newer version of the DSS from the AM65X version with the major change being the addition of another OLDI TX. With the help of 2 OLDI TXes, the AM625 DSS supports OLDI displays with a resolution of upto 2K. This patch set further adds support for the OLDI on AM625, and is, in essence, the second version of the following patch series: https://patchwork.kernel.org/project/dri-devel/list/?series=660970&state=%2A&archive=both The changes in the above-mentioned series forced some re-works in this series, and are better reviewed as a single set. TODO: - Support for OLDI Bridges that work on clone / dual-link modes is yet to be added. - The pixel clock for the OLDI VP passes through a clock divider, which was being explicitly set in previous series, but that was not the right way. That patch has been dropped and a newer implementation is in works. Note: - Due to lack of hardware, only dual-link mode has been tested.
