+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 combiner
Is it really only one interrupt or two as in case of Exynos4x12 ?
Also it's probably more appropriate to say "interrupt controller"
instead of "combiner", not including details of the the FIMC-IS external
interrupt controller in this binding.
+- 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.
+- pmu : phandle to the fimc-is pmu node describing the register
+ base and size for FIMC-IS PMU.
This property needs to be prefixed with "samsung,".
+
+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
nit: As pointed out already there is no need for the apostrophe.
+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.
