[PATCH v6 0/6] dt-bindings: msm/dp: Add support for 4 pixel streams

[Dmitry Baryshkov]

On some MSM chipsets, the display port controller is capable of supporting
up to 4 streams.

To drive these additional streams, the pixel clocks for the corresponding
stream needs to be enabled.

Fixup the documentation of some of the bindings to clarify exactly which
stream they correspond to, then add the new bindings and device tree
changes.

Note: SC7280 changes depend on clock driver changes and will be posted
