[v4,13/13] arm64: dts: qcom: sa8295-adp: Enable DP instances
Commit Message
From: Bjorn Andersson <bjorn.andersson@linaro.org>
The SA8295P ADP has, among other interfaces, six MiniDP connectors which
are connected to MDSS0 DP2 and DP3, and MDSS1 DP0 through DP3.
Enable Display Clock controllers, MDSS instanced, MDPs, DP controllers,
DP PHYs and link them all together.

That's quite a lot of indentation.. couldn't these endpoints be defined
in the SoC DT?

Thanks for pointing that out. Would be nice if the computer told me
that...somehow...

The alternative would be to have the description of each DP controller
split over multiple nodes and rely on the reader to stitch together the
view of the node based on the label.
Based on the naming of these labels they would at least be adjacent, so
it wouldn't be that bad.
But I feel that there is enough DP-controller nodes in this board
already; I've yet to describe the two USB Type-C controllers or the two
DSI-DP bridges.
So I don't know if it's worth optimizing indentation-level within each
node like this.
And we will end up mixing this optimization between DP controllers, USB
Type-C nodes, QMP nodes, DSI-DP bridges.

Bjorn

Oh okay, I see, let's keep it as-is then.
