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,cal" +- reg: physical base address and length of the registers set for the 4 + memory regions required; +- reg-names: name associated with the memory regions described is <reg>; +- 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. Please +refer to the bindings defined in +Documentation/devicetree/bindings/media/video-interfaces.txt. + +Example: + cal: cal@4845b000 { + compatible = "ti,cal"; + ti,hwmods = "cal"; + reg = <0x4845B000 0x400>, + <0x4845B800 0x40>, + <0x4845B900 0x40>, + <0x4A002e94 0x4>; + reg-names = "cal_top", + "cal_rx_core0", + "cal_rx_core1", + "camerrx_control"; + interrupts = <GIC_SPI 119 IRQ_TYPE_LEVEL_HIGH>; + #address-cells = <1>; + #size-cells = <0>; + + csi2_0: port@0 { + #address-cells = <1>; + #size-cells = <0>; + reg = <0>; + endpoint { + slave-mode; + remote-endpoint = <&ar0330_1>; + }; + }; + csi2_1: port@1 { + #address-cells = <1>; + #size-cells = <0>; + reg = <1>; + }; + }; + + i2c5: i2c@4807c000 { + ar0330@10 { + compatible = "ti,ar0330"; + reg = <0x10>; + + port { + #address-cells = <1>; + #size-cells = <0>; + + ar0330_1: endpoint { + reg = <0>; + clock-lanes = <1>; + data-lanes = <0 2 3 4>; + remote-endpoint = <&csi2_0>; + }; + }; + }; + }; -- 1.8.5.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
