| 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. |
