bring UP 需要做的工作1、kernelspace sensor driver ： 驱动和设备树2、userspacecamera 对应的chromatix library 和sensor library准备工作1、模组原理图 2、sensor spec3、sensor resolution代码准备1、kernel1、设备树qcom,camera@20 {compatible =“qcom,imx111”;reg = <0x20>;qcom,slave-id =<0x20 0x0 0x111>; //(slave id – 0x20, chip id address – 0x0, chip id –0x111)qcom,csiphy-sd-index= <0>; //(Use CSIPHY subdev 0)qcom,csid-sd-index= <0>; //(Use CSID subdev 0)qcom,flash-src-index= <&led_flash0>; //(Use LED flash subdev 0)qcom,mount-angle =<90>; //(mount angle 90 degree)qcom,sensor-name =“imx111”;// (sensor name)cam_vdig-supply =<&pm8941_l3>;// (Use L3 for VDIG)cam_vana-supply =<&pm8941_l23>;// (Use L23 for VANA)cam_vio-supply =<&pm8941_lvs2>; //(Use xndmz for VIO)cam_vaf-supply =<&pm8941_l17>; //(Use L17 for VAF)qcom,cam-vreg-name= “cam_vdig”, “cam_vio”, “cam_vana”, “cam_vaf”;qcom,cam-vreg-type= <0 1 0 0>; //(0 – LDO, 1 – LVS)qcom,cam-vreg-min-voltage= <1225000 0 2850000 2850000>;// (min voltage)qcom,cam-vreg-max-voltage= <1225000 0 2850000 2850000>;// (max voltage)qcom,cam-vreg-op-mode= <105000 0 80000 100000>; //(Optimum mode)qcom,gpio-no-mux =<0>;gpios =<&msmgpio 15 0>, <&msmgpio 90 0>;qcom,gpio-reset =<1>; //(Use gpio pin 90 for reset)qcom,gpio-req-tbl-num= <0 1>; //(0 – pin 15, 1 – pin 90)qcom,gpio-req-tbl-flags= <1 0>; //(0 – output gpio, 1 – input gpio)qcom,gpio-req-tbl-label= “CAMIF_MCLK”, “CAM_RESET1”; //(gpio name)qcom,gpio-set-tbl-num= <1 1>;// (1 – pin 90)qcom,gpio-set-tbl-flags= <0 2>; //(0 – GPIOF_OUT_INIT_LOW, 2 -qcom,gpio-set-tbl-delay= <1000 4000>; //(delay in micro sec)qcom,csi-lane-assign= <0x4320>; //(Use 0x4320 for CSI lane assign)qcom,csi-lane-mask= <0x1F>; //(Use 0x1F for lane mask)qcom,sensor-position= <0>; //(0 – back camera, 1 – front camera)qcom,sensor-mode =<1>;// (1 – 2D, 3 – 3D)qcom,cci-master =<0>; //(0 – Master 0, 1 – Master 1)status = “ok”;};2、驱动vendor（chromatix library）1、vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/modules/sensors/chromatix/0301/libchromatix/chromatix_imx111/使用高通的chromatix tunning 软件生成头文件。2、vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/modules/sensors/sensor_libs/imx111/需要配置以下信息：1）init, start, stop寄存器配置2）coarse_int_time_addr 、global_gain_addr 寄存器地址3）x_output 、y_output、line_length_pclk 、frame_length_lines 寄存器地址4）full/half resolution 寄存器配置5）配置每个every resolution 对应xxddx library 6）配置每个resolution 对应的sensor_out_info structsensor_lib_out_info_t sensor_out_info花痴的板栗 = {
