在8X12平台添加或者移植一个完整的camera
以OV8865为例
1、kernel部分：
A、kernel_driver:把驱动文件ov8865_qtech_f8865ac.c 放到kernel/drivers/media/platform/msm/camera_v2/sensor/目录下
B、kernel_dtsi:
把如下板级信息加到 kernel/arch/arm/boot/dts/msm8610-qrd-camera-sensor.dtsi文件中
actuator1: qcom,actuator@18 {
cell-index = <4>;
reg = <0x18>;
compatible = "qcom,actuator";
qcom,cci-master = <0>;
};
eeprom0:qom,eeprom@2b{
cell-index = <0>;
reg = <0x2b 0x0>;
...
...
｝；
qcom,camera@7f {
compatible = "qcom,ov8865_qtech";
reg = <0x7f>;
qcom,slave-id = <0x6c 0x300b 0x8865>;
qcom,csid-sd-index = <0>;

cam_vdig-supply = <&pm8110_l7>;
cam_vana-supply = <&pm8110_l19>;
cam_vio-supply = <&pm8110_l14>;
qcom,cam-vreg-name = "cam_vdig", "cam_vio", "cam_vana";

qcom,cam-vreg-op-mode = <200000 200000 100000>;
qcom,gpio-no-mux = <0>;
gpios = <&msmgpio 13 0>,
<&msmgpio 21 0>,
<&msmgpio 20 0>,
<&pm8110_gpios 2 0>;
qcom,gpio-reset = <1>;
qcom,gpio-standby = <2>;
qcom,gpio-vdig = <3>;
qcom,gpio-req-tbl-num = <0 1 2 3>;

qcom,csi-lane-mask = <0x3>;
qcom,sensor-position = <0>;
qcom,sensor-mode = <1>;
qcom,cci-master = <0>;};
C、kernel-clock:
这部分主要是针对 B 的，增加一些I2C地址
如下代码断：

+++ b/arch/arm/mach-msm/clock-8610.c

D、把C文件加到Makefile

+obj-y +=ov8865_qtech_f8865ac.o
kernel部分就这么多了，此时可以先编译一个bootimage看看能不能编译过。
2、vendor部分
这一部分主要包括：效果（chromatix）、马达AF驱动（actuators）、库文件（sensor_libs）
A、效果（chromatix）：把chromatix_ov8865_qtech_f8865ac整个文件夹放到vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/modules/sensors/chromatix/0301/libchromatix/下
B、马达AF驱动（actuators） ：把af_main_cam_camcorder_6.h、af_main_cam_camera_6.h AF头文件放到vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/modules/sensors/actuators/0301/目录下。
同时做如下工作：
--- a/mm-camera/mm-camera2/media-controller/modules/sensors/actuators/actuator.c
+++ b/mm-camera/mm-camera2/media-controller/modules/sensors/actuators/actuator.c

#include "af_main_cam_camcorder_5.h"
+ #include "af_main_cam_camcorder_6.h"
}
};在af_main_cam_camcorder_6.h中会有af_header_info_t：
如下：
/* af_header_info_t */
{
/* header_version */
0x301,
/* cam_name */
ACTUATOR_MAIN_CAM_6,
/* module_name */
"ov8865",
/* actuator_name */
"BU64243GWZ",
}, /* af_header_info_t */
其中ACTUATOR_MAIN_CAM_6这个需要在kernel中定义，在kernel/include/media/msm_cam_sensor.h文件中添加ACTUATOR_MAIN_CAM_6
enum af_camera_name {
ACTUATOR_MAIN_CAM_0,
ACTUATOR_MAIN_CAM_1,
ACTUATOR_MAIN_CAM_2,
ACTUATOR_MAIN_CAM_3,

ACTUATOR_MAIN_CAM_5,
ACTUATOR_MAIN_CAM_6
ACTUATOR_WEB_CAM_0,
ACTUATOR_WEB_CAM_1,
ACTUATOR_WEB_CAM_2,
};
C、库文件（sensor_libs） ：把ov8865_qtech_f8865ac整个文件夹放到vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/modules/sensors/sensor_libs/目录下
D、把相关文件添加到config中，如下：
