1 Broadcom BCM2835 auxiliar SPI1/2 controller
3 The BCM2835 contains two forms of SPI master controller, one known simply as
4 SPI0, and the other known as the "Universal SPI Master"; part of the
5 auxiliary block. This binding applies to the SPI1/2 controller.
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
15 - cs-gpios: the cs-gpios (native cs is NOT supported)
