|  | 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>; | 
|  | }; | 
|  | }; | 
|  | }; |
