1Texas Instruments AM437x CAMERA (VPFE) 2-------------------------------------- 3 4The Video Processing Front End (VPFE) is a key component for image capture 5applications. The capture module provides the system interface and the 6processing capability to connect RAW image-sensor modules and video decoders 7to the AM437x device. 8 9Required 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 20VPFE 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 22defined in Documentation/devicetree/bindings/media/video-interfaces.txt. 23 24Example: 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 };
