-Broadcom BCM2835 auxiliary 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
-- interrupts: Should contain shared interrupt of the aux block
-- clocks: The clock feeding the SPI controller - needs to
- point to the auxiliary clock driver of the bcm2835,
- as this clock will enable the output gate for the specific
- clock.
-- cs-gpios: the cs-gpios (native cs is NOT supported)
- see also spi-bus.txt
-
-Example:
-
-spi1@7e215080 {
- compatible = "brcm,bcm2835-aux-spi";
- reg = <0x7e215080 0x40>;
- interrupts = <1 29>;
- clocks = <&aux_clocks BCM2835_AUX_CLOCK_SPI1>;
- #address-cells = <1>;
- #size-cells = <0>;
- cs-gpios = <&gpio 18>, <&gpio 17>, <&gpio 16>;
-};
-
-spi2@7e2150c0 {
- compatible = "brcm,bcm2835-aux-spi";
- reg = <0x7e2150c0 0x40>;
- interrupts = <1 29>;
- clocks = <&aux_clocks BCM2835_AUX_CLOCK_SPI2>;
- #address-cells = <1>;
- #size-cells = <0>;
- cs-gpios = <&gpio 43>, <&gpio 44>, <&gpio 45>;
