1Exynos ISP SPI Subsystem
2
3The device node for ISP SPI subsytem.
4Since Peripheral id in EXYNOS is decoded based on Interrupts, currently
5ISP SPI have no individual interrupts hence we add ad dummy interrupt node
6which will have a value beyond the maximum number of interrupts exynos5 can
7support.
8
9Required properties :
10 - compatible : Should be "samsung,exynos-spi" for spi.
11 - reg : Base adrress of the the subsystem.
12 - interrupts : A value which is beyond the maximum number of interrupts
13exynos5 can support.

15Example:
16spi@131a0000 {
17	#address-cells = <1>;
18	#size-cells = <0>;
19	compatible = "samsung,exynos-spi";
20	reg = <0x131a0000 0x30>;
21	interrupts = <0 129 0>;
22};
