1Broadcom BCM2835 auxiliar SPI1/2 controller
2
3The BCM2835 contains two forms of SPI master controller, one known simply as
4SPI0, and the other known as the "Universal SPI Master"; part of the
5auxiliary block. This binding applies to the SPI1/2 controller.
6
7Required properties:
8- compatible: Should be "brcm,bcm2835-aux-spi".
9- reg: Should contain register location and length for the spi block
10- interrupts: Should contain shared interrupt of the aux block
11- clocks: The clock feeding the SPI controller - needs to
12	  point to the auxiliar clock driver of the bcm2835,
13	  as this clock will enable the output gate for the specific
14	  clock.
15- cs-gpios: the cs-gpios (native cs is NOT supported)
