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>;
};
};
};
