1Andestech ATCSPI200 SPI controller Device Tree Bindings
2-------------------------------------------------------
3ATCSPI200 is a Serial Peripheral Interface (SPI) controller
4which serves as a SPI master or a SPI slave.
5
6It is often be embedded in AE3XX and AE250 platforms.
7
8Required properties:
9- compatible: has to be "andestech,atcspi200".
10- reg: Base address and size of the controllers memory area.
11- #address-cells: <1>, as required by generic SPI binding.
12- #size-cells: <0>, also as required by generic SPI binding.
13- interrupts: Property with a value describing the interrupt number.
14- clocks: Clock phandles (see clock bindings for details).
15- spi-max-frequency: Maximum SPI clocking speed of device in Hz.
16
17Optional properties:
18- num-cs: Number of chip selects used.

20Example:
21
22	spi: spi@f0b00000 {
23		compatible = "andestech,atcspi200";
24		reg = <0xf0b00000 0x1000>;
25		#address-cells = <1>;
26		#size-cells = <0>;
27		num-cs = <1>;
28		clocks = <&spiclk>;
29		interrupts = <3 4>;
30		flash@0 {
31			compatible = "spi-flash";
32			spi-max-frequency = <50000000>;
33			reg = <0>;
34			spi-cpol;
35			spi-cpha;
36		};
37	};
