Merge tag 'bcm2835-for-3.10-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-rpi into next/dt
From Stephen Warren <swarren@wwwdotorg.org>:
ARM: bcm2835: device tree updates
This branch adds two devices to the BCM2835 SoC device tree: the SPI
controller and the HW random number generator.
The SPI controller isn't actually instantiated in the Raspberry Pi
device tree, since there are no on-board SPI devices; it's up to the
end-user to modify their own device-tree to describe whatever they
have attached.
* tag 'bcm2835-for-3.10-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-rpi:
ARM: bcm2835: add Broadcom BCM2835 RNG to the device tree
ARM: bcm2835: add SPI device to DT
