This series moves the tidss to using new connectoe model, where the SoC driver (tidss) creates the connector and all the bridges are attached with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR. It also now creates bridge to support format negotiation and and 'simple' encoder to expose it to the userspace. Since the bridges do not create the connector, the bus_format and bus_flag is set via atomic hooks. Support format negotiations in the tfp410, sii902x and mhdp-8546 bridge drivers as a first step before moving the connector model. These patches were tested on AM625-SK EVM, AM625 SoC based BeaglePlay, and J721E-SK. Display support for AM625 SoC has not been added upstream and is a WIP. To test this series on AM625 based platforms, basic display support patches, (for driver + devicetree), can be found in the "next_AttachNoConn-v2" branch on my github fork[2]. Thanks, Aradhya [1]: https://patchwork.freedesktop.org/series/82765/#rev5 [2]: https://github.com/aradhya07/linux-ab/tree/next_AttachNoConn-v2 Change Log: V6 -> V7 - Rebase and cosmetic changes. - Drop the output format check condition for mhdp8546 and hence, drop Tomi Valkeinen's R-b tag. - Added tags wherever suggested. V5 -> V6 - Rebase and cosmetic changes - Dropped the output format check condition for tfp410 and hence, dropped Tomi Valkeinen's and Laurent Pinchart's R-b tags. - Based on Boris Brezillon's comments: dropped patches 5 and 6 from the series and instead created a single patch that, 1. Creates tidss bridge for format negotiation. 2. Creates 'simple' encoder for userspace exposure. 3. Creates a tidss connector. 4. Attaches the next-bridge to encoder with the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag. - Add format negotiation support for sii902x driver.
