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