  The SC8280XP currently shows depressing results in memory benchmarks.
Fix this by introducing support for the platform in the OSM (and EPSS)
L3 driver and support for the platform in the bwmon binding.

Then add the necessary nodes and values throughout the sc8280xp and
sa8540p dtsi files to make the various devices on these platforms scale
both L3, memory bus and DDR.

Bjorn Andersson (10):
  interconnect: qcom: osm-l3: Use platform-independent node ids

Good stuff! Thanks Bjorn!

I plan to merge everything except the dts patches, that should go
through the qcom tree.

BR,
