| 2 | -------------------------------------- |
| 3 | |
| 4 | The Video Processing Front End (VPFE) is a key component for image capture |
| 5 | applications. The capture module provides the system interface and the |
| 6 | processing capability to connect RAW image-sensor modules and video decoders |
| 7 | to the AM437x device. |
| 8 | |
| 9 | Required properties: |
| 10 | - compatible: must be "ti,am437x-vpfe" |
| 11 | - reg: physical base address and length of the registers set for the device; |
| 12 | - interrupts: should contain IRQ line for the VPFE; |
| 13 | - ti,am437x-vpfe-interface: can be one of the following, |
| 14 | 0 - Raw Bayer Interface. |
| 15 | 1 - 8 Bit BT656 Interface. |
| 16 | 2 - 10 Bit BT656 Interface. |
| 17 | 3 - YCbCr 8 Bit Interface. |
| 18 | 4 - YCbCr 16 Bit Interface. |
| 19 | |
| 20 | VPFE supports a single port node with parallel bus. It should contain one |
| 21 | 'port' child node with child 'endpoint' node. Please refer to the bindings |
| 22 | defined in Documentation/devicetree/bindings/media/video-interfaces.txt. |
| 23 | |
| 24 | Example: |
| 25 | vpfe: vpfe@f0034000 { |
| 26 | compatible = "ti,am437x-vpfe"; |
| 27 | reg = <0x48328000 0x2000>; |
| 28 | interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>; |
| 29 | |
| 30 | pinctrl-names = "default", "sleep"; |
| 31 | pinctrl-0 = <&vpfe_pins_default>; |
| 32 | pinctrl-1 = <&vpfe_pins_sleep>; |
| 33 | |
| 34 | port { |
| 35 | #address-cells = <1>; |
| 36 | #size-cells = <0>; |
| 37 | |
| 38 | vpfe0_ep: endpoint { |
| 39 | remote-endpoint = <&ov2659_1>; |
| 40 | ti,am437x-vpfe-interface = <0>; |
| 41 | bus-width = <8>; |
| 42 | hsync-active = <0>; |
| 43 | vsync-active = <0>; |
| 44 | }; |
| 45 | }; |
| 46 | }; |
| 47 | |
| 48 | i2c1: i2c@4802a000 { |
| 49 | |
| 50 | ov2659@30 { |
| 51 | compatible = "ti,ov2659"; |
| 52 | reg = <0x30>; |
| 53 | |
| 54 | port { |
| 55 | ov2659_1: endpoint { |
| 56 | remote-endpoint = <&vpfe0_ep>; |
| 57 | bus-width = <8>; |
| 58 | mclk-frequency = <12000000>; |
| 59 | }; |
| 60 | }; |
| 61 | }; |
