The capture module provides the system interface and the +processing capability to connect CSI2 image-sensor modules to the +DRA72x device. + +Required properties: +- compatible: must be "ti,dra72-cal" +- reg: CAL Top level, Receiver Core #0, Receiver Core #1 and Camera RX + control address space +- reg-names: cal_top, cal_rx_core0, cal_rx_core1, and camerrx_control + registers +- interrupts: should contain IRQ line for the CAL; + +CAL supports 2 camera port nodes on MIPI bus. Each CSI2 camera port nodes +should contain a 'port' child node with child 'endpoint' node.
