+Exynos4x12 SoC series Imaging Subsystem (FIMC-IS)
+
+The FIMC-IS is an subsystem for processing image signal from an image sensor.
+The Exynos4x12 SoC series FIMC-IS V1.5 comprises of a dedicated ARM Cortex-A5
+processor, ISP, DRC and FD IP blocks and peripheral IPs such as I2C, SPI, UART
+bus controllers, Multi-PWM and ADC.
+
+fimc-is node
+------------
+
+Required properties:
+
+- compatible : should be "samsung,exynos4212-fimc-is" for Exynos4212 and
+	       Exynos4412 SoCs;
+- reg	     : physical base address and size of the device memory mapped
+	       registers;
+- interrupts : should contain FIMC-IS interrupts;
+
+The following are the FIMC-IS peripheral device nodes and can be specified
+either standalone or as fimc-is child nodes.
+
+pmu subnode
+-----------
+
+Required properties:
+ - reg	: should contain PMU physical base address of the memory mapped
+          registers and size, the value of size should be 0x3000.
+
+
+i2c-isp (ISP I2C bus controller) nodes
+------------------------------------------
+
+Required properties:
+
+- compatible : should be "samsung,exynos4212-i2c-isp" for Exynos4212 and
+	       Exynos4412 SoCs;
+- reg	     : physical base address and size of the device memory mapped
+	       registers;
+
+For the above nodes it is required to specify a pinctrl state named "default",
+according to the pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt.
