From: Martin Sperl <kernel at martin.sperl.org>

This patch series adds the bcm2835aux uart driver, which is created
as a wrapper arround the 8250 driver (based on recommendations by
Stephen Warren)

Also (as per request) the recommendation for naming conventions of nodes
in the device-tree have been followed for both the primary uart as well
as for the auxiliar uart: nodes should be called "serial at ...".

The device tree patches will not apply cleanly as:
* the bcm-auxiliar clock device tree patch has not been applied to
  upstream yet (but it is pending).
* there is a rename of arch/arm/boot/dts/bcm2835.dtsi
  scheduled, which is also not upstream yet.

I want to get this patch out before I go on vacation not waiting for
it to appear. If necessary please modify the corresponding patches.

  ARM: bcm2835: follow dt uart node-naming convention
  dt/bindings: serial: bcm2835: add binding documentation for
  serial: bcm2835: add driver for bcm2835-aux-uart
  ARM: bcm2835: add bcm2835-aux-uart support to default DT
