1*cb9b23cdSRajeshwari ShindeExynos ISP SPI Subsystem
2*cb9b23cdSRajeshwari Shinde
3*cb9b23cdSRajeshwari ShindeThe device node for ISP SPI subsytem.
4*cb9b23cdSRajeshwari ShindeSince Peripheral id in EXYNOS is decoded based on Interrupts, currently
5*cb9b23cdSRajeshwari ShindeISP SPI have no individual interrupts hence we add ad dummy interrupt node
6*cb9b23cdSRajeshwari Shindewhich will have a value beyond the maximum number of interrupts exynos5 can
7*cb9b23cdSRajeshwari Shindesupport.
8*cb9b23cdSRajeshwari Shinde
9*cb9b23cdSRajeshwari ShindeRequired properties :
10*cb9b23cdSRajeshwari Shinde - compatible : Should be "samsung,exynos-spi" for spi.
11*cb9b23cdSRajeshwari Shinde - reg : Base adrress of the the subsystem.
12*cb9b23cdSRajeshwari Shinde - interrupts : A value which is beyond the maximum number of interrupts
13*cb9b23cdSRajeshwari Shindeexynos5 can support.

15*cb9b23cdSRajeshwari ShindeExample:
16*cb9b23cdSRajeshwari Shindespi@131a0000 {
17*cb9b23cdSRajeshwari Shinde	#address-cells = <1>;
18*cb9b23cdSRajeshwari Shinde	#size-cells = <0>;
19*cb9b23cdSRajeshwari Shinde	compatible = "samsung,exynos-spi";
20*cb9b23cdSRajeshwari Shinde	reg = <0x131a0000 0x30>;
21*cb9b23cdSRajeshwari Shinde	interrupts = <0 129 0>;
