Shouldn't it be, e.g.: Samsung EXYNOS5 SoC series Imaging Subsystem (FIMC-IS) Or do you intend this file to be describing also the other sub-devices, like GScaler ?
+----------------------------------- + +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 +- 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. + + +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
What pins exactly are supposed to be covered by these properties ? For what devices ? Aren't the camera port pins supposed to be specified at the common 'camera' node ? I believe the camera ports are not specific to the FIMC-IS.
+pmu subnode +----------- + +Required properties: + - reg : should contain PMU physical base address and size of the memory + mapped registers.
What about other devices, like ISP I2C, SPI ? Don't you want to list at least
the ones currently used (I2C bus controllers) ? Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
