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 0qcom,page0 = <1 0x100 2 0x01 1 1>;qcom,poll0 = <0 0x0 2 0 1 1>;qcom,mem0 = <0 0x0 2 0 1 0>;qcom,page1 = <1 0x0A02 2 0x01 1 1>;qcom,poll1 = <0 0x0 2 0 1 1>;qcom,mem1 = <0 0x0 2 0 1 0>;qcom,page2 = <1 0x0A00 2 0x01 1 100>;qcom,poll2 = <0 0x0 2 0 1 1>;qcom,mem2 = <64 0x0A04 2 0 1 0>;//page 1qcom,page3 = <1 0x100 2 0x01 1 1>;qcom,poll3 = <0 0x0 2 0 1 1>;qcom,mem3 = <0 0x0 2 0 1 0>;qcom,page4 = <1 0x0A02 2 0x02 1 1>;qcom,poll4 = <0 0x0 2 0 1 1>;qcom,mem4 = <0 0x0 2 0 1 0>;qcom,page5 = <1 0x0A00 2 0x01 1 100>;qcom,poll5 = <0 0x0 2 0 1 1>;qcom,mem5 = <64 0x0A04 2 0 1 0>;//page 2qcom,page6 = <1 0x100 2 0x01 1 1>;qcom,poll6 = <0 0x0 2 0 1 1>;qcom,mem6 = <0 0x0 2 0 1 0>;qcom,page7 = <1 0x0A02 2 0x03 1 1>;qcom,poll7 = <0 0x0 2 0 1 1>;qcom,mem7 = <0 0x0 2 0 1 0>;qcom,page8 = <1 0x0A00 2 0x01 1 100>;qcom,poll8 = <0 0x0 2 0 1 1>;qcom,mem8 = <64 0x0A04 2 0 1 0>;cam_vio-supply = <&pm660_l11>;cam_vana-supply = <&cam_avdd_gpio_regulator>;cam_vdig-supply = <&cam_dvdd_gpio_regulator>;qcom,cam-vreg-name = "cam_vio", "cam_vana", "cam_vdig";qcom,cam-vreg-min-voltage = <1780000 0 0>;qcom,cam-vreg-max-voltage = <1950000 0 0>;qcom,cam-vreg-op-mode = <105000 0 0>;qcom,gpio-no-mux = <0>;pinctrl-names = "cam_default", "cam_suspend";pinctrl-0 = <&cam_sensor_mclk1_active&cam_sensor_front_active>;pinctrl-1 = <&cam_sensor_mclk1_suspend&cam_sensor_front_suspend>;gpios = <&tlmm 33 0>,<&tlmm 47 0>;qcom,gpio-reset = <1>;qcom,gpio-req-tbl-num = <0 1>;qcom,gpio-req-tbl-flags = <1 0>;qcom,gpio-req-tbl-label = "CAMIF_MCLK1","CAM_RESET1";qcom,cam-power-seq-type = "sensor_gpio","sensor_vreg","sensor_vreg","sensor_vreg","sensor_clk","sensor_gpio";qcom,cam-power-seq-val =  "sensor_gpio_reset","cam_vdig","cam_vana","cam_vio","sensor_cam_mclk","sensor_gpio_reset";qcom,cam-power-seq-cfg-val = <0 1 1 1 24000000 1>;qcom,cam-power-seq-delay = <1 1 1 0 1 11>;qcom,sensor-position = <1>;qcom,sensor-mode = <0>;qcom,cci-master = <1>;status = "ok";clocks = <&clock_mmss MCLK1_CLK_SRC>,<&clock_mmss MMSS_CAMSS_MCLK1_CLK>;clock-names = "cam_src_clk", "cam_clk";qcom,clock-rates = <24000000 0>;
};

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。
