0001 Texas Instruments AM437x CAMERA (VPFE)
0002 --------------------------------------
0003
0004 The Video Processing Front End (VPFE) is a key component for image capture
0005 applications. The capture module provides the system interface and the
0006 processing capability to connect RAW image-sensor modules and video decoders
0007 to the AM437x device.
0008
0009 Required properties:
0010 - compatible: must be "ti,am437x-vpfe"
0011 - reg: physical base address and length of the registers set for the device;
0012 - interrupts: should contain IRQ line for the VPFE;
0013 - ti,am437x-vpfe-interface: can be one of the following,
0014 0 - Raw Bayer Interface.
0015 1 - 8 Bit BT656 Interface.
0016 2 - 10 Bit BT656 Interface.
0017 3 - YCbCr 8 Bit Interface.
0018 4 - YCbCr 16 Bit Interface.
0019
0020 VPFE supports a single port node with parallel bus. It should contain one
0021 'port' child node with child 'endpoint' node. Please refer to the bindings
0022 defined in Documentation/devicetree/bindings/media/video-interfaces.txt.

0024 Example:
0025 vpfe: vpfe@f0034000 {
0026 compatible = "ti,am437x-vpfe";
0027 reg = <0x48328000 0x2000>;
0028 interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>;
0029
0030 pinctrl-names = "default", "sleep";
0031 pinctrl-0 = <&vpfe_pins_default>;
0032 pinctrl-1 = <&vpfe_pins_sleep>;
0033
0034 port {
0035 #address-cells = <1>;
0036 #size-cells = <0>;
0037
0038 vpfe0_ep: endpoint {
0039 remote-endpoint = <&ov2659_1>;
0040 ti,am437x-vpfe-interface = <0>;
0041 bus-width = <8>;
0042 hsync-active = <0>;
0043 vsync-active = <0>;
0044 };
0045 };
0046 };
0047
0048 i2c1: i2c@4802a000 {
0049
0050 ov2659@30 {
0051 compatible = "ti,ov2659";
0052 reg = <0x30>;
0053
0054 port {
0055 ov2659_1: endpoint {
0056 remote-endpoint = <&vpfe0_ep>;
0057 bus-width = <8>;
0058 mclk-frequency = <12000000>;
0059 };
0060 };
0061 };
