+Exynos ISP SPI Subsystem
+
+The device node for ISP SPI subsytem.
+Since Peripheral id in EXYNOS is decoded based on Interrupts, currently
+ISP SPI have no individual interrupts hence we add ad dummy interrupt node
+which will have a value beyond the maximum number of interrupts exynos5 can
+support.
+
+Required properties :
+ - compatible : Should be "samsung,exynos-spi" for spi.
+ - reg : Base adrress of the the subsystem.
+ - interrupts : A value which is beyond the maximum number of interrupts
+exynos5 can support.
+
+Example:
+spi@131a0000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "samsung,exynos-spi";
+ reg = <0x131a0000 0x30>;
+ interrupts = <0 129 0>;

+Exynos Sound Subsystem
+
+The device node for sound subsytem which contains codec and i2s block
+that is a part of Exynos5250
+
+Required properties :
+ - compatible : Should be "samsung,exynos-sound" for sound
+ - samsung,i2s-epll-clock-frequency : epll clock output frequency in Hz
+ - samsung,i2s-sampling-rate : sampling rate, default is 48000
+ - samsung,i2s-bits-per-sample : sample width, defalut is 16 bit
+ - samsung,i2s-channels : nummber of channels, default is 2
+ - samsung,i2s-lr-clk-framesize : lr clock frame size
+ - samsung,i2s-bit-clk-framesize : bit clock frame size
+ - samsung,codec-type : sound codec type
+
+Example:
+
+sound@12d60000 {
+ compatible = "samsung,exynos-sound"
+ samsung,i2s-epll-clock-frequency = <192000000>;
