[Intel-gfx] [PATCH v6 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 panel programming. Rest of the patches will be published
to GITHUB.

v2: Addressed review comments from Jani N for Patches 1-6 and rebase for some
other few patches.
v3: Renamed intel_dsi_new.c to gen11_dsi.c as per discussion with Jani, Daniel,
    Ville. Also addressed review comments for couple of patches.
v4: Rename gen11_dsi.c to icl_dsi.c (Ville). No functional changes.
v5: Rebase on drm-tip after initial 7 patches got merged.
v6: Addressed various review comments from Jani N, Ville, Vandita.
