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 platform changes. Main theme this merge window:

   - The Netx platform (Netx 100/500) platform is removed by Linus
     Walleij-- the SoC doesn't have active maintainers with hardware,
     and in discussions with the vendor the agreement was that it's OK
     to remove.

   - Russell King has a series of patches that cleans up and refactors
     SA1101 and RiscPC support"
