Pull ARM SoC late updates from Arnd Bergmann:
 "This is some material that we picked up into our tree late or that had
  complex inter-depondencies. The fact that there are these
  interdependencies tends to meant that these are often actually the
  most interesting new additions:

   - The new Aspeed AST2600 baseboard management controller is added,
     this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and
     had some dependencies on other device drivers.

   - After many years, support for the MMP2 based OLPC XO-1.75 finally
     makes it into the kernel.

   - The Armada 3720 based Turris Mox open source router platform is a
     late addition and it follows some preparatory work across multiple
     branches.

   - The OMAP2+ platform had some large-scale cleanup involving driver
     changes and DT changes, here we finish it off, dropping a lot of
     the now-unused platform data.

   - The TI K3 platform that got added for 5.3 gains a lot more support
     for individual bits on the SoC, this part just came late for the
     merge window"

[ This pull request itself wasn't actually sent late at all by Arnd, but
  I waited on the branches that it used to be pulled first, so it ends
  up being merged much later than the other ARM SoC pull requests this
  merge window     - Linus ]
