Merge tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC board updates from Olof Johansson:
"This branch is reducing in size for every release since most
board-related changes have started happening in devicetrees now.
Still, we have some things going on here.
* Renesas platforms are still adding a bit more legacy device
support, something that should trail off shortly as they move to
full DT
* We group most defconfig updates into this branch out of old habits
* Removal of legacy OMAP2 platforms over to DT continues, and a
handful of old code is being removed here"
* tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (94 commits)
