Add the fimc-is node and the required pinctrl nodes for
fimc-is driver for Exynos5. Also adds the DT binding documentation
for the new fimc-is node.

+Samsung EXYNOS SoC Camera Subsystem
+-----------------------------------
+
+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 removed the FIMC-CAPTURE. Instead it has an improved
+FIMC-IS which can provide imate data DMA output.
+
+The device tree binding remain similar to the Exynos4 bindings which can
+be seen at samsung-fimc.txt with the addition of fimc-is sub-node which will
+be explained here.
+
+fimc-is subnode of camera 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
+
+Board specific properties:
+
+- pinctrl-names : pinctrl names for camera port pinmux control, at least
+ "default" needs to be specified.
+- pinctrl-0...N : pinctrl properties corresponding to pinctrl-names
+
+Sensor sub-nodes:
+
+FIMC-IS IP supports custom built sensors to be controlled exclusively by
+the FIMC-IS firmware. These sensor properties are to be defined here.
+Sensor nodes are described in the same way as in generic sensors used in
+Exynos4 and described in samsung-fimc.txt.
+
+Example:
+
+SoC common node:
+
+ fimc_is: fimc-is@13000000 {
+ compatible = "samsung,exynos5250-fimc-is";
+ reg = <0x13000000 0x200000>;
+ interrupt-parent = <&combiner>;
+ interrupts = <19 1>;
+ status = "disabled";
+ };
+
+Board specific node:
+
+ fimc-is@13000000 {
+ status = "okay";
+ pinctrl-0 =
+ <&cam_port_a_clk_active
+ &cam_bayer_clk_active
+ &isp_uart
+ &cam_i2c0
+ &cam_i2c1>;
+ pinctrl-names = "default";
+ s5k4e5 {
+ compatible = "samsung,s5k4e5";
+ gpios = <&gpx1 2 1>;
+ clock-frequency = <24000000>;
+ port {
+ is_s5k4e5_ep: endpoint {
+ remote-endpoint = <&csis0_ep>;
+ };
+ };
+ };
+ s5k6a3 {
+ compatible = "samsung,s5k6a3";
+ gpios = <&gpx1 0 1>;
+ clock-frequency = <24000000>;
+ port {
+ is_s5k6a3_ep: endpoint {
+ remote-endpoint = <&csis1_ep>;
+ };
+ };
+ };
+ };
