1 | Exynos4x12 SoC series Imaging Subsystem (FIMC-IS) |
| 2 | ||
| 3 | The FIMC-IS is a subsystem for processing image signal from an image sensor. | |
| 4 | The Exynos4x12 SoC series FIMC-IS V1.5 comprises of a dedicated ARM Cortex-A5 | |
| 5 | processor, ISP, DRC and FD IP blocks and peripheral devices such as UART, I2C | |
| 6 | and SPI bus controllers, PWM and ADC. | |
| 7 | ||
| 8 | fimc-is node | |
| 9 | ------------ | |
| 10 | ||
| 11 | Required properties: | |
| 12 | - compatible : should be "samsung,exynos4212-fimc-is" for Exynos4212 and | |
| 13 | Exynos4412 SoCs; | |
| 14 | - reg : physical base address and length of the registers set; | |
| 15 | - interrupts : must contain two FIMC-IS interrupts, in order: ISP0, ISP1; | |
| 16 | - clocks : list of clock specifiers, corresponding to entries in | |
| 17 | clock-names property; | |
| 18 | - clock-names : must contain "ppmuispx", "ppmuispx", "lite0", "lite1" | |
| 19 | "mpll", "sysreg", "isp", "drc", "fd", "mcuisp", "uart", | |
| 20 | "ispdiv0", "ispdiv1", "mcuispdiv0", "mcuispdiv1", "aclk200", | |
| 21 | "div_aclk200", "aclk400mcuisp", "div_aclk400mcuisp" entries, | |
| 22 | matching entries in the clocks property. | |
| 23 | pmu subnode | |
| 24 | ----------- | |
| 25 | ||
| 26 | Required properties: | |
| 27 | - reg : must contain PMU physical base address and size of the register set. | |
| 28 | ||
| 29 | The following are the FIMC-IS peripheral device nodes and can be specified | |
| 30 | either standalone or as the fimc-is node child nodes. | |
| 31 | ||
| 32 | i2c-isp (ISP I2C bus controller) nodes | |
| 33 | ------------------------------------------ | |
| 34 | ||
| 35 | Required properties: | |
| 36 | ||
| 37 | - compatible : should be "samsung,exynos4212-i2c-isp" for Exynos4212 and | |
| 38 | Exynos4412 SoCs; | |
| 39 | - reg : physical base address and length of the registers set; | |
| 40 | - clocks : must contain gate clock specifier for this controller; | |
| 41 | - clock-names : must contain "i2c_isp" entry. | |
| 42 | ||
| 43 | For the above nodes it is required to specify a pinctrl state named "default", | |
| 44 | according to the pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt. | |
| 45 | ||
| 46 | Device tree nodes of the image sensors' controlled directly by the FIMC-IS | |
| 47 | firmware must be child nodes of their corresponding ISP I2C bus controller node. | |
| 48 | The data link of these image sensors must be specified using the common video | |
| 49 | interfaces bindings, defined in video-interfaces.txt. |
