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 : should contain "samsung,exynos5250-fimc-is" +- reg : physical base address and size of the memory mapped + registers +- interrupts : interrupt-specifier for the fimc-is interrupt +- 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 +-------------------------------------- +The i2c-isp nodes should be children of the fimc-is node. + +Required properties: + +- compatible : must contain "samsung,exynos4212-i2c-isp" for Exynos4212, + Exynos4412 and Exynos5250 SoCs +- reg : physical base address and length of the registers set +- clocks : should contain gate clock specifier for this controller +- clock-names : should contain "i2c_isp" for the gate clock +- pinctrl-0 : phandle of the pinctrl node for the i2c isp +- pinctrl-names : must contain "default" + +ranges, #address-cells, and #size-cells should be present as appropriate. + +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. + +Example: + + fimc_is: fimc-is@13000000 { + compatible = "samsung,exynos5250-fimc-is"; + #address-cells = <1>; + #size-cells = <1>; + ranges; + reg = <0x13000000 0x200000>; + interrupt-parent = <&combiner>; + interrupts = <19 1>; + clocks = <&clock 346>, <&clock 347>, <&clock 512>, + <&clock 513>, <&clock 514>, <&clock 515>, + <&clock 516>; + clock-names = "isp", "mcu_isp", "isp_div0", "isp_div1", + "isp_divmpwm", "mcu_isp_div0", + "mcu_isp_div1"; + samsung,pmu = <&pmu>; + + i2c0_isp: i2c-isp@13130000 { + compatible = "samsung,exynos4212-i2c-isp"; + reg = <0x13130000 0x100>; + #address-cells = <1>; + #size-cells = <0>; + clocks = <&clock 352>; + clock-names = "i2c_isp"; + pinctrl-0 = <&cam_i2c0_bus>; + pinctrl-names = "default"; + }; + + i2c1_isp: i2c-isp@13140000 { + compatible = "samsung,exynos4212-i2c-isp"; + reg = <0x13140000 0x100>; + #address-cells = <1>; + #size-cells = <0>; + clocks = <&clock 353>; + clock-names = "i2c_isp"; + pinctrl-0 = <&cam_i2c1_bus>; + pinctrl-names = "default"; + }; + }; + +In the board specific file the sensor nodes can be provided.
