ARM: bcm2835: device tree updates

Browse Source 
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.

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.
