-Texas Instruments AM437x CAMERA (VPFE)
---------------------------------------
-
-The Video Processing Front End (VPFE) is a key component for image capture
-applications. The capture module provides the system interface and the
-processing capability to connect RAW image-sensor modules and video decoders
-to the AM437x device.
-
-Required properties:
-- compatible: must be "ti,am437x-vpfe"
-- reg: physical base address and length of the registers set for the device;
-- interrupts: should contain IRQ line for the VPFE;
-- ti,am437x-vpfe-interface: can be one of the following,
- 0 - Raw Bayer Interface.
- 1 - 8 Bit BT656 Interface.
- 2 - 10 Bit BT656 Interface.
- 3 - YCbCr 8 Bit Interface.
- 4 - YCbCr 16 Bit Interface.
-
-VPFE supports a single port node with parallel bus. It should contain one
-'port' child node with child 'endpoint' node. Please refer to the bindings
-defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
-
-Example:
- vpfe: vpfe@f0034000 {
- compatible = "ti,am437x-vpfe";
- reg = <0x48328000 0x2000>;
- interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>;
-
- pinctrl-names = "default", "sleep";
- pinctrl-0 = <&vpfe_pins_default>;
- pinctrl-1 = <&vpfe_pins_sleep>;
-
- port {
- #address-cells = <1>;
- #size-cells = <0>;
-
- vpfe0_ep: endpoint {
- remote-endpoint = <&ov2659_1>;
- ti,am437x-vpfe-interface = <0>;
- bus-width = <8>;
- hsync-active = <0>;
- vsync-active = <0>;
- };
- };
- };
-
- i2c1: i2c@4802a000 {
-
- ov2659@30 {
- compatible = "ti,ov2659";
- reg = <0x30>;
-
- port {
- ov2659_1: endpoint {
- remote-endpoint = <&vpfe0_ep>;
- bus-width = <8>;
- mclk-frequency = <12000000>;
- };
- };
- };
