如何增加一种新的传感器

Step1

/device/mediatek/ ${project} /ProjectConfig.mk
/kernel-4.4/arch/arm64/configs/ ${project}_debug_defconfig
/kernel-4.4/arch/arm64/configs/${project}_defconfig

1.1ProjectConfig.mk 如下修改
(a) 修改imgsensor相关
eg:main(后摄) xxx_mipi_raw, sub (前摄)xxxx_mipi_raw, main2(stereo)xxxx_mipi_raw)

• CUSTOM_HAL_IMGSENSOR = xxxx_mipi_raw
• CUSTOM_KERNEL_IMGSENSOR = xxxx_mipi_raw
• CUSTOM_HAL_MAIN_IMGSENSOR = xxxx_mipi_raw
• CUSTOM_HAL_SUB_IMGSENSOR = xxxx_mipi_raw
• CUSTOM_KERNEL_MAIN_IMGSENSOR = xxxx_mipi_raw
• CUSTOM_KERNEL_SUB_IMGSENSOR = xxxx_mipi_raw
• CUSTOM_HAL_MAIN2_IMGSENSOR = xxxx_mipi_raw
• CUSTOM_KERNEL_MAIN2_IMGSENSOR = xxxx_mipi_raw
