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>;

qcom,actuator-src = <&actuator1>;

qcom,eeprom-src = <&eeprom0>;

qcom,led-flash-src = <&led_flash0>;

qcom,mount-angle = <90>;

qcom,sensor-name = "ov8865_qtech";

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-type = <0 0 0>;

qcom,cam-vreg-min-voltage = <1500000 1800000 2850000>;

qcom,cam-vreg-max-voltage = <1500000 1800000 2850000>;

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,gpio-req-tbl-flags = <1 0 0 0>;

qcom,gpio-req-tbl-label = "CAMIF_MCLK",

"CAM_RESET1",

"CAM_STANDBY",

"CAM_VDIG";

qcom,csi-lane-assign = <0xe4>;

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

@@ -13,7 +14,7 @@

#include "af_main_cam_camcorder_4.h"

#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_4,

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：
