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

[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

[PATCH v6 1/6] dt-bindings: display/msm: dp-controller: allow eDP for SA8775P

[Dmitry Baryshkov]

On Qualcomm SA8775P the DP controller might be driving either a
DisplayPort or a eDP sink (depending on the PHY that is tied to the
controller). Reflect that in the schema.

[PATCH v6 2/6] dt-bindings: display/msm: qcom,x1e80100-mdss: correct DP addresses

[Dmitry Baryshkov]

From: Abhinav Kumar <quic_abhinavk@quicinc.com>

Fix c&p error and correct example to use 32-bit addressing (as the rest
of the example DT does) instead of 64-bit (as the platform does).  It
got unnoticed before since DP controller node wasn't validated against
DT schema because of the missing compatible.

[PATCH v6 4/6] dt-bindings: display/msm: drop assigned-clock-parents for dp controller

[Dmitry Baryshkov]

From: Abhinav Kumar <quic_abhinavk@quicinc.com>

DP controller schema documents assigned-clocks and
assigned-clock-parents. However these assignments should not be a part
of the ABI: there are no actual requirements on the order of the
assignments, MST cases require different number of clocks to be
assigned, etc.

Instead of fixing up the documentation, drop the assigned-clock-parents
and assigned-clocks from the bindings. The generic clock/clock.yaml
already covers these properties.

[PATCH v6 5/6] dt-bindings: display/msm: add stream pixel clock bindings for MST

[Dmitry Baryshkov]

From: Abhinav Kumar <quic_abhinavk@quicinc.com>

On a vast majority of Qualcomm chipsets DisplayPort controller can
support several MST streams (up to 4x). To support MST these chipsets
use up to 4 stream pixel clocks for the DisplayPort controller. Expand
corresponding clock bindings for these platforms and fix example
schema files to follow updated bindings.

Note: On chipsets that do support MST, the number of streams supported
can vary between controllers. For example, SA8775P supports 4 MST
streams on mdss_dp0 but only 2 streams on mdss_dp1.
