+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 fimc-is pmu node describing the register
+ base and size for FIMC-IS PMU.
As this is a phandle to the whole SoC Power Management Unit I would amend
this to something like:
- 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.
Thanks,
Sylwester
