From: Martin Sperl <[email protected]>
This patch-series adds the spi-bcm2835aux driver to the kernel.
After a long discussion of how to enable/disable the hw block,
which resulted in multiple versions, the consensus is now
that the clk-bcm2835-aux clock driver is responsible for
enabling/disabling the HW block.
So there is a dependency of this device-driver on the
clock driver that supplies that functionality.

dt/bindings: bcm2835: spi: add bindings for the bcm2835 auxiliary spi
devices
spi: bcm2835: add bcm2835 auxiliary spi device driver
spi: bcm2835: add the auxiliary spi1 and spi2 to the device tree
ARM: bcm2835: enable auxiliary spi driver in defaultconfig
