1*4882a593SmuzhiyunTexas Instruments AM437x CAMERA (VPFE) 2*4882a593Smuzhiyun-------------------------------------- 3*4882a593Smuzhiyun 4*4882a593SmuzhiyunThe Video Processing Front End (VPFE) is a key component for image capture 5*4882a593Smuzhiyunapplications. The capture module provides the system interface and the 6*4882a593Smuzhiyunprocessing capability to connect RAW image-sensor modules and video decoders 7*4882a593Smuzhiyunto the AM437x device. 8*4882a593Smuzhiyun 9*4882a593SmuzhiyunRequired properties: 10*4882a593Smuzhiyun- compatible: must be "ti,am437x-vpfe" 11*4882a593Smuzhiyun- reg: physical base address and length of the registers set for the device; 12*4882a593Smuzhiyun- interrupts: should contain IRQ line for the VPFE; 13*4882a593Smuzhiyun- ti,am437x-vpfe-interface: can be one of the following, 14*4882a593Smuzhiyun 0 - Raw Bayer Interface. 15*4882a593Smuzhiyun 1 - 8 Bit BT656 Interface. 16*4882a593Smuzhiyun 2 - 10 Bit BT656 Interface. 17*4882a593Smuzhiyun 3 - YCbCr 8 Bit Interface. 18*4882a593Smuzhiyun 4 - YCbCr 16 Bit Interface. 19*4882a593Smuzhiyun 20*4882a593SmuzhiyunVPFE supports a single port node with parallel bus. It should contain one 21*4882a593Smuzhiyun'port' child node with child 'endpoint' node.
