+Broadcom BCM2835 auxiliar SPI1/2 controller
+
+The BCM2835 contains two forms of SPI master controller, one known simply as
+SPI0, and the other known as the "Universal SPI Master"; part of the
+auxiliary block. This binding applies to the SPI1/2 controller.
+
+Required properties:
+- compatible: Should be "brcm,bcm2835-aux-spi".
+- reg: Should contain register location and length for the spi block
+       as well as for the common aux block control
+- interrupts: Should contain shared interrupt of the aux block
+- clocks: The clock feeding the SPI controller.
+- cs-gpios: the cs-gpios (native cs is NOT supported)

it would be nice to reference to spi-bus.txt here, just like the other bindings does.

- cs-gpios: see spi-bus.txt (native chip-select is NOT supported)

Beside that try to get a feedback from the devicetree maintainers.

Stefan
