1Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL) 2------------------------------------------------------ 3 4The Camera Adaptation Layer (CAL) is a key component for image capture 5applications. The capture module provides the system interface and the 6processing capability to connect CSI2 image-sensor modules to the 7DRA72x device. 8 9Required properties: 10- compatible: must be "ti,dra72-cal" 11- reg: CAL Top level, Receiver Core #0, Receiver Core #1 and Camera RX 12 control address space 13- reg-names: cal_top, cal_rx_core0, cal_rx_core1, and camerrx_control 14 registers 15- interrupts: should contain IRQ line for the CAL; 16 17CAL supports 2 camera port nodes on MIPI bus. Each CSI2 camera port nodes 18should contain a 'port' child node with child 'endpoint' node. Please 19refer to the bindings defined in 20Documentation/devicetree/bindings/media/video-interfaces.txt. 21 22Example: 23 cal: cal@4845b000 { 24 compatible = "ti,dra72-cal"; 25 ti,hwmods = "cal"; 26 reg = <0x4845B000 0x400>, 27 <0x4845B800 0x40>, 28 <0x4845B900 0x40>, 29 <0x4A002e94 0x4>; 30 reg-names = "cal_top", 31 "cal_rx_core0", 32 "cal_rx_core1", 33 "camerrx_control"; 34 interrupts = <GIC_SPI 119 IRQ_TYPE_LEVEL_HIGH>; 35 #address-cells = <1>; 36 #size-cells = <0>; 37 38 ports { 39 #address-cells = <1>; 40 #size-cells = <0>; 41 42 csi2_0: port@0 { 43 reg = <0>; 44 endpoint { 45 slave-mode; 46 remote-endpoint = <&ar0330_1>; 47 }; 48 }; 49 csi2_1: port@1 { 50 reg = <1>; 51 }; 52 }; 53 }; 54 55 i2c5: i2c@4807c000 { 56 ar0330@10 { 57 compatible = "ti,ar0330"; 58 reg = <0x10>; 59 60 port { 61 #address-cells = <1>; 62 #size-cells = <0>; 63 64 ar0330_1: endpoint { 65 reg = <0>; 66 clock-lanes = <1>; 67 data-lanes = <0 2 3 4>; 68 remote-endpoint = <&csi2_0>; 69 }; 70 }; 71 }; 72 }; 73
