1Exynos4x12 SoC series Imaging Subsystem (FIMC-IS)
2
3The FIMC-IS is a subsystem for processing image signal from an image sensor.
4The Exynos4x12 SoC series FIMC-IS V1.5 comprises of a dedicated ARM Cortex-A5
5processor, ISP, DRC and FD IP blocks and peripheral devices such as UART, I2C
6and SPI bus controllers, PWM and ADC.

8fimc-is node
9------------
10
11Required 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.
23pmu subnode
24-----------
25
26Required properties:
27 - reg : must contain PMU physical base address and size of the register set.
28
29The following are the FIMC-IS peripheral device nodes and can be specified
30either standalone or as the fimc-is node child nodes.
31
32i2c-isp (ISP I2C bus controller) nodes
33------------------------------------------
34
35Required 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
43For the above nodes it is required to specify a pinctrl state named "default",
44according to the pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt.
45
46Device tree nodes of the image sensors' controlled directly by the FIMC-IS
47firmware must be child nodes of their corresponding ISP I2C bus controller node.
48The data link of these image sensors must be specified using the common video
49interfaces bindings, defined in video-interfaces.txt.
