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"
