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.

|
|
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;
|
|

clock-names property;
|
|
|
|
|
- clock-names : must contain "ppmuispx", "ppmuispx", "lite0", "lite1"

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.
