Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC platform updates from Olof Johansson:
 "SoC updates, mostly refactorings and cleanups of old legacy platforms.

  Major themes this release:

   - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)

   - Moving some of the ep93xx headers around to get it closer to
     multiplatform enabled.

   - Cleanups of Davinci

  This also contains a few patches that were queued up as fixes before
  5.1 but I didn't get sent in before release"

+description: |
+  On the IXP4xx SoCs, the Network Processing Engine (NPE) is a small
+  processor that can load a firmware to perform offloading of networking
+  and crypto tasks. It also manages the MDIO bus to the ethernet PHYs
+  on the IXP4xx platform. All IXP4xx platforms have three NPEs at
+  consecutive memory locations. They are all included in the same
+  device node since they are not independent of each other.
