[Intel-gfx] [PATCH v2 00/20] ICELAKE DSI DRIVER

[Madhav Chauhan]

>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 and will share the GITHUB link so that complete
implementation can be looked at by reviewers.

v2: Addressed review comments from Jani N for Patches 1-6 and rebase for some
other few patches.
