- Exynos4x12 SoC series Imaging Subsystem (FIMC-IS)
- The FIMC-IS is a subsystem for processing image signal from an image sensor.
- The Exynos4x12 SoC series FIMC-IS V1.5 comprises of a dedicated ARM Cortex-A5
- processor, ISP, DRC and FD IP blocks and peripheral devices such as UART, I2C
- and SPI bus controllers, PWM and ADC.
- fimc-is node
- ------------
- Required properties:
- - compatible : should be "samsung,exynos4212-fimc-is" for Exynos4212 and
- Exynos4412 SoCs;
- - reg : physical base address and length of the registers set;
- - interrupts : must contain two FIMC-IS interrupts, in order: ISP0, ISP1;
- - clocks : list of clock specifiers, corresponding to entries in
- clock-names property;
- - clock-names : must contain "ppmuispx", "ppmuispx", "lite0", "lite1"
- "mpll", "sysreg", "isp", "drc", "fd", "mcuisp", "uart",
- "ispdiv0", "ispdiv1", "mcuispdiv0", "mcuispdiv1", "aclk200",
- "div_aclk200", "aclk400mcuisp", "div_aclk400mcuisp" entries,
- matching entries in the clocks property.
- pmu subnode
- -----------
- Required properties:
- - reg : must contain PMU physical base address and size of the register set.
- The following are the FIMC-IS peripheral device nodes and can be specified
- either standalone or as the fimc-is node child nodes.
- i2c-isp (ISP I2C bus controller) nodes
- ------------------------------------------
- Required properties:
- - compatible : should be "samsung,exynos4212-i2c-isp" for Exynos4212 and
- Exynos4412 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 above nodes 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.
