Can I have a DT binding maintainer Ack for this binding ?
I'd like to queue this patch for 3.13 once the merge window has closed.

+Samsung EXYNOS5 SoC series Imaging Subsystem (FIMC-IS)
+------------------------------------------------------
+
+The camera subsystem on Samsung Exynos5 SoC has some changes relative
+to previous SoC versions. Exynos5 has almost similar MIPI-CSIS and
+FIMC-LITE IPs but has a much improved version of FIMC-IS which can
+handle sensor controls and camera post-processing operations. The
+Exynos5 FIMC-IS has a dedicated ARM Cortex A5 processor, many
+post-processing blocks (ISP, DRC, FD, ODC, DIS, 3DNR) and two
+dedicated scalers (SCC and SCP).
+
+fimc-is node
+------------
+
+Required properties:
+
+- compatible : must be "samsung,exynos5250-fimc-is"
+- reg : physical base address and size of the memory mapped
+ registers
+- interrupt-parent : parent interrupt controller
+- interrupts : fimc-is interrupt to the parent interrupt controller
+- clocks : list of clock specifiers, corresponding to entries in
+ clock-names property
+- clock-names : must contain "isp", "mcu_isp", "isp_div0", "isp_div1",
+ "isp_divmpwm", "mcu_isp_div0", "mcu_isp_div1" entries,
+ matching entries in the clocks property
+- samsung,pmu : phandle to the Power Management Unit (PMU) node
+
+i2c-isp (ISP I2C bus controller) nodes
+------------------------------------------
+
+Required properties:
+
+- compatible : should be "samsung,exynos4212-i2c-isp" for Exynos4212,
+ Exynos4412 and Exynos5250 SoCs
+- reg : physical base address and length of the registers set
+- clocks : must contain gate clock specifier for this controller
+- clock-names : must contain "i2c_isp" entry
+
+For the i2c-isp node, it is required to specify a pinctrl state named
"default",
+according to the pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt.
+
+Device tree nodes of the image sensors controlled directly by the FIMC-IS
+firmware must be child nodes of their corresponding ISP I2C bus controller
node.
+The data link of these image sensors must be specified using the common video
+interfaces bindings, defined in video-interfaces.txt.
