1.1 kernel层：

1.1.1 eeprom读取地址、大小和sensor上电时序等配置（dts配置）：

file path：kernel/arch/arm/boot/dts/qcom/sdm660-camera-sensor-mtp_gm8plus.dtsi

example：

eeprom2: qcom,eeprom@2 {
cell-index = <2>;
reg = <0x2>;
compatible = "qcom,eeprom";

qcom,eeprom-name = "s5k3h7_sunny_a8s05a_front_i";
qcom,i2c-freq-mode = <1>;
qcom,slave-addr = <0x20>;
qcom,num-blocks = <9>;

//page 0

qcom,mem2 = <64 0x0A04 2 0 1 0>;

//page 1

qcom,poll5 = <0 0x0 2 0 1 1>;
qcom,mem5 = <64 0x0A04 2 0 1 0>;

//page 2
qcom,page6 = <1 0x100 2 0x01 1 1>;
qcom,poll6 = <0 0x0 2 0 1 1>;

};

key note：

1.eeprom一页的读取示例解析：

//page 0
qcom,page0 = <1 0x100 2 0x01 1 1>; //打开stream（解析：向0x100地址的寄存器中写0x01）
qcom,poll0 = <0 0x0 2 0 1 1>;
qcom,mem0 = <0 0x0 2 0 1 0>;

qcom,page1 = <1 0x0A02 2 0x01 1 1>; //设置page
qcom,poll1 = <0 0x0 2 0 1 1>;
qcom,mem1 = <0 0x0 2 0 1 0>;

qcom,page2 = <1 0x0A00 2 0x01 1 100>; //使能读
qcom,poll2 = <0 0x0 2 0 1 1>;
qcom,mem2 = <64 0x0A04 2 0 1 0>; //读数据（解析：以0xa04为起始地址，读取64个字节大小的数据）

2.sensor的电源gpio配置与上电时序要写正确。

1.2 hal层：

1.2.1 添加eeprom驱动文件：

file path：

vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/modules/sensors/eeprom/libs/

example：

1.创建sensor的eeprom的文件夹。

2.添加sensor的eeprom的驱动文件:

(1)<sensor>_eeprom.c

(2)<sensor>_eeprom.h

(3)Makefile

1.2.2 配置<project&platform>_camera.xml文件：

file path：vendor/qcom-proprietary/mm-camera/mm-camera2/media-controller/modules/sensors/configs/gm8plus_camera.xml

example：

添加下述代码中的<EepromName>：

<CameraModuleConfig>
<CameraId>2</CameraId>
<SensorName>s5k3h7_sunny_a8s05a_front_i</SensorName>
<EepromName>s5k3h7_sunny_a8s05a_front_i</EepromName>
<FlashName>pmic</FlashName>
<ChromatixName>s5k3h7_sunny_a8s05a_front_i_chromatix</ChromatixName>
<ModesSupported>1</ModesSupported>
<Position>FRONT</Position>
<MountAngle>270</MountAngle>
<CSIInfo>
<CSIDCore>2</CSIDCore>
<LaneMask>0x1F</LaneMask>
<LaneAssign>0x4320</LaneAssign>
<ComboMode>0</ComboMode>
</CSIInfo>
<LensInfo>
<FocalLength>1.97</FocalLength>
<FNumber>2.0</FNumber>
<TotalFocusDistance>1.9</TotalFocusDistance>
<HorizontalViewAngle>84.0</HorizontalViewAngle>
<VerticalViewAngle>63.0</VerticalViewAngle>
<MinFocusDistance>0.1</MinFocusDistance>
</LensInfo>
</CameraModuleConfig>

1.2.3 把前面所有make file中的LOCAL_MODULE添加最终的make file（device-vendor.mk）：

file path：vendor/qcom/proprietary/common/config/device-vendor.mk

example：

MM_CAMERA += libmmcamera_s5k3h7_sunny_a8s05a_front_i_eeprom

key note：example中的s5k3h7_sunny_a8s05a_front_i_eeprom要与《1.2.1》添加的Makefile文件中的LOCAL_MODULE、《1.2.2》配置的xml文件中的<EepromName>一致。
