这个是是对qcom camera bring up的补充：/wing12345678910/article/details/79261931
添加了eeprom actuator pdaf
文档参考sensor的bring up：/wing12345678910/article/details/79261931
EEPROM
eeprom的添加
在vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/module/sensor/config/xxx_camera.xml
中对应的模组添加eeprom
<EepromName>eeprom的名字</EepromName> 注意该名字要与驱动中名字相对应
修改dtsi文件
kernel/arch/arm/boot/qcom/dts/xxx-camera-sensor-xxx.dtsi
中添加对eeprom的配置
eeprom0: qcom,eeprom@0 {
cell-index = <0>;
compatible = "qcom,eeprom";
qcom,cci-master = <0>;
reg = <0x0>;
cam_vdig-supply = <&pm8937_l23>;
cam_vana-supply = <&pm8937_l22>;
cam_vio-supply = <&pm8937_l6>;
cam_vaf-supply = <&pm8937_l17>;
qcom,cam-vreg-name = "cam_vdig", "cam_vana", "cam_vio",
"cam_vaf";
qcom,cam-vreg-min-voltage = <1200000 0 2800000 2850000>; //这里的大多配置参考sensor就可以
qcom,cam-vreg-max-voltage = <1200000 0 2800000 2850000>;
qcom,cam-vreg-op-mode = <200000 0 80000 100000>;
}
sensor中添加：
qcom,camera@0 {
cell-index = <0>;
compatible = "qcom,camera";
reg = <0x0>;
qcom,csiphy-sd-index = <0>;
qcom,csid-sd-index = <0>;
qcom,mount-angle = <270>;
qcom,led-flash-src = <&led_flash0>;
qcom,eeprom-src = <&eeprom0>;
qcom,actuator-src = <&actuator0>;
cam_vana-supply = <&pm8937_l22>;
cam_vio-supply = <&pm8937_l6>;
cam_vaf-supply = <&pm8937_l17>;
...
驱动文件的添加：
vendor/qcom/properietary/mm-camera/mm-camera2/media-controller/module/sensor/eeprom/lib/XXXX/
驱动文件包含三部分：
Android.mk
xxx_eeprom.c
xxx_eeprom.h
.c文件是对读到的数据按照datashit进行解析
.h文件中主要涉及到power_up和power_down，mem_map_array(寄存器的相关设置)
actuator的添加：
actuator的驱动添加基本与eeprom一致
在kernel/arch/arm/boot/qcom/dts/xxx-camera-sensor-xxx.dtsi中添加设备
vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/module/sensor/config/xxx_camera.xml添加配置
vendor/qcom/properietary/mm-camera/mm-camera2/media-controller/module/sensor/actuator/lib/添加驱动文件
pdaf的添加
在vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/module/sensor/sensor/lib/xxx/
目录下添加驱动文件：xxx_pdaf.h xxx_pdaf_flip_mirror.h
注意在sensor的驱动中需要添加对padf的配置：
在res的配置中有：is_pdaf_supported 该值为1说明支持pdaf
.pdaf_config = {
#ifndef FLIP_MIRROR
#include "xxx_pdaf.h"
#else
#include "xxx_pdaf_flip_mirror.h"
#endif
}
