dt-bindings: display/ti: Simplify dma-coherent property

2025-12-16T13:59:30Z

Common boolean properties need to be only allowed in the binding (":true"), because their type is already defined by core DT schema. Simplify dma-coherent property to match common syntax.

dt-bindings: display: ti: Add schema for AM625 OLDI Transmitter

2025-06-26T09:37:08Z

The OLDI transmitters (TXes) do not have registers of their own, and are dependent on the source video-ports (VPs) from the DSS to provide configuration data. This hardware doesn't directly sit on the internal bus of the SoC, but does so via the DSS. Hence, the OLDI TXes are supposed to be child nodes under the DSS, and not independent devices. Two of the OLDI TXes can function in tandem to output dual-link OLDI output, or cloned single-link outputs. In these cases, one OLDI will be the primary OLDI, and the other one, a companion. The following diagram represents such a configuration. +-----+-----+ +-------+ | | | | | | | VP1 +----+--->+ OLDI0 | (Primary - may need companion) | | | | | | | DSS +-----+ | +-------+ | | | | | | VP2 | | +-------+ | | | | | | +-----+-----+ +--->+ OLDI1 | (Companion OLDI) | | +-------+ The DSS in AM625 SoC has a configuration like the one above. The AM625 DSS VP1 (port@0) can connect and control 2 OLDI TXes, to use them in dual-link or cloned single-link OLDI modes. It is only the VP1 that can connect to either OLDI TXes for the AM625 DSS, and not the VP2. Alternatively, on some future TI SoCs, along with the above configuration, the OLDI TX can _also_ connect to separate video sources, making them work entirely independent of each other. In this case, neither of the OLDIs are "companion" or "secondary" OLDIs, and nor do they require one. They both are independent and primary OLDIs. The following diagram represents such a configuration. +-----+-----+ +-------+ | | | | | | | VP1 +--+----------->+ OLDI0 | (Primary - may need companion) | | | | | | | +-----+ | +-------+ | | | | | | VP2 | | | | | | | DSS +-----+ | +---+ +-------+ | | | +-->+ M | | | | | VP3 +----->+ U +--->+ OLDI1 | (Companion or Primary) | | | | X | | | | +-----+ +---+ +-------+ | | | | | VP4 | | | | +-----+-----+ Note that depending on the mux configuration, the OLDIs can either be working together in tandem - sourced by VP1, OR, they could be working independently sourced by VP1 and VP3 respectively. The idea is to support all the configurations with this OLDI TX schema. The OLDI functionality is further supported by a system-control module, which contains a few registers to control OLDI IO power and other electrical characteristics of the IO lanes. Add devicetree binding schema for the OLDI TXes to support various configurations, and extend their support to the AM625 DSS.

dt-bindings: display: ti,am65x-dss: Add support for AM62L DSS

2025-05-20T11:43:56Z

The DSS controller on TI's AM62L SoC is an update from that on TI's AM625/AM65x/AM62A7 SoC. The AM62L DSS [1] only supports a single display pipeline using a single overlay manager, single video port and a single video lite pipeline which does not support scaling. The output of video port is routed to SoC boundary via DPI interface and the DPI signals from the video port are also routed to DSI Tx controller present within the SoC.

dt-bindings: display: ti,am65x-dss: Add support for common1 region

2024-02-19T11:12:50Z

TI keystone display subsystem present in AM65, AM62 and AM62A SoC support two separate register spaces namely "common" and "common1" which can be used by two separate hosts to program the display controller as described in respective Technical Reference Manuals [1]. The common1 register space has similar set of configuration registers as supported in common register space except the global configuration registers which are exclusive to common region. This adds binding for "common1" register region too as supported by the hardware.

The DSS controller on TI's AM625 SoC is an update from that on TI's AM65X SoC. The former has an additional OLDI TX on its first video port that helps output cloned video or WUXGA (1920x1200@60fps) resolution video output over a dual-link mode to reduce the required OLDI clock output. The second video port is same from AM65x DSS and it outputs DPI video data. It can support 2K resolutions @ 60fps, independently. Add the new controller's compatible and update descriptions.
