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 +- 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. + +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. -- 1.7.9.5
