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:
"Board updates for 3.12. Again, a bit of domain overlap with SoC and
DT branches, but most of this is around legacy code and board support.
We've found that platform maintainers have a hard time separating all
of these out and might move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and
clocksource setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas
Lager.
- New backlight drivers for backlights used on Renesas shmobile
platforms.
- Removal of Renesas leds driver.
- Shuffling of some of the new Broadcom platforms to give room for
others in the same mach directory. More in 3.13"
