>From ICELAKE platform onwards, new MIPI DSI IP controller is integrated to GPU/Display Engine and same could be extended for future Intel platforms as well. DSI IP controller supports MIPI DSI 1.3 and DPHY 1.2 specification. So, a new DSI driver has been added inside I915. Given below patches are the part of new DSI driver which implements BSPEC sequence till transcoder configuration. Rest of the patches (~45) will be published to GITHUB by mid next week and will share the GITHUB link here so that complete implementation can be looked at by reviewers.
