[PATCH v6 0/4] spi: bcm2835: add spi-bcm2835aux driver

[kernel@xxxxxxxxxxxxxxxx]

From: Martin Sperl <kernel@xxxxxxxxxxxxxxxx>

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.

Martin Sperl (4):
  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
