+Broadcom BCM2835 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.
+- gpio-cs: the gpio-cs (native cs is NOT supported)
+
+Example:
+
+spi1@7e215080 {
+ compatible = "brcm,bcm2835-aux-spi";
+ reg = <0x7e215080 0x40>, <0x7e215000 0x08>;
+ interrupts = <1 29>;
+ clocks = <&clk_spi>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+};
+
+spi2@7e215080 {
+ compatible = "brcm,bcm2835-aux-spi";
+ reg = <0x7e2150c0 0x40>, <0x7e215000 0x08>;
+ interrupts = <1 29>;
+ clocks = <&clk_spi>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+};
