高通Android Camera Actuator的移植

介紹
自動對焦功能需要靠馬達帶動鏡片移動來實現，在拍照時候仔細聽能聽到對焦馬達發出的咔咔聲。因此，在Camera sensor bring up以後，就需要關注這個部分的控制。
這篇文章主要介紹在高通平臺的CamX框架裡面，如何去點亮攝像頭馬達，需要修改哪些相關的檔案。
mm-camera 也是類似的。
大體瀏覽
先來個整體的瀏覽，看下涉及到需要修改哪些目錄下的檔案。要讓馬達運轉起來，我們需要修改的基本就是下面4個目錄下的相關檔案。
| 目錄 | 意義 |
|---|---|
| vendor/qcom/proprietary/chi-cdk/oem/qcom/actuator | 各種型號的馬達配置檔案目錄 |
| vendor/qcom/proprietary/chi-cdk/oem/qcom/module | Camera sensor配置檔案目錄 |
| vendor/qcom/proprietary/chi-cdk/tools/buildbins | 各個Camera sensor編譯配置的檔案目錄 |
| vendor/qcom/proprietary/camera-devicetree | dtsi檔案相關，主要配置Camera sensor上電時序等資訊 |
修改檔案內容詳細分析
例如，某個sensor是s5k3p9sx、馬達型號是dw9763。
actuator配置
路徑：vendor/qcom/proprietary/chi-cdk/oem/qcom/actuator
這個目錄下，是各個型號的馬達配置檔案，高通原始碼裡面已經有一些比較常見的馬達型號的配置檔案，我們可以進行參考。
vendor/qcom/proprietary/chi-cdk/oem/qcom/actuator$ ls ak7371_actuator.xml dw9714v_actuator.xml dw9763b_actuator.xml gt9764_actuator.xml lc898217xc_actuator.xml ak7374_actuator.xml dw9718s_actuator.xml dw9767_actuator.xml gt9772_actuator.xml bu64297gwz_actuator.xml dw9763_actuator.xml dw9800_actuator.xml
我們隨便打開個xml的檔案：cat dw9763_actuator.xml
<?xml version="1.0" encoding="utf-8" ?>

基本上，用到的Camera sensor的xml，需要根據實際情況進行配置：
-
如果xml不存在，那麼需要在
vendor/qcom/proprietary/chi-cdk/oem/qcom/actuator添加個一個xml的檔案。模組廠會給我們提供關於該顆sensor的相關文件，我們需要獲取的馬達相關資訊，也能從提供的文件中找到。 -
如果sersor 用的馬達型號對應的xml已經有了，那基於初始配置就可以了。
根據實際硬體情況，只需要做少量的改動即可（甚至不需要）。
常見的改動有：
- slaveAddress ：i2c裝置地址。
- i2cFrequencyMode：i2c速率。
- 上下電時序需要根據資料手冊進行修改。
camera sensor配置
路徑：vendor/qcom/proprietary/chi-cdk/oem/qcom/module
這個目錄下，就是關於camera sensor的配置檔案了，關於某顆sensor的的詳細資訊，是在這邊進行建立新增的。
vendor/qcom/proprietary/chi-cdk/oem/qcom/module$ ls

...
同樣地，隨便開啟一個module配置：cat truly_s5k3p9sx_module.xml

如果是廠商會提供這樣的配置，那是最好，基本上不用怎麼修改，但如果是自己弄的話，就需要注意以下部分：
- actuatorName：馬達名稱（例如
dw9763），這個部分要和上面的actuator配置中的actuatorName匹配 - cameraId：要和裝置樹匹配。
- position：前後攝像頭等
編譯系統
上面的2個配置已經配好了，但是需要在這裡進行編輯才能夠編譯進驅動中。
yaml檔案
路徑： vendor/qcom/proprietary/chi-cdk/tools/buildbins
vendor/qcom/proprietary/chi-cdk/tools/buildbins$ ls
buildbins_bengal.yaml buildbins_lito.yaml buildbins_sm6150.yaml linux64 win32
buildbins_kona.yaml buildbins.py buildbins.yaml NOTICE yaml
在Camx架構中，各個功能模組（每顆sensor的module和turning等模組），都可以編譯成各自獨立的so檔案。
修改某個模組的內容後，我們可以切到chi-cdk目錄下，進行mm編譯，編譯生成的對應so檔案在vendor/lib*/目錄下。
我們開啟其中一個yaml檔案，看下里面的內容：
sensor_drivers:
- com.qti.sensormodule.truly_s5k3p9sx:
- sensor/default/s5k3p9sx/s5k3p9sx_sensor.xml
- sensor/default/s5k3p9sx/s5k3p9sx_pdaf.xml # 新增
- module/truly_s5k3p9sx_module.xml
- actuator/default/dw9763_actuator.xml # 新增
- flash/back_sensor_flash.xml
...
mk檔案
路徑：vendor/qcom/proprietary/common/config/device-vendor.mk
確保對應的camera-sensor以及actuator編譯進：
...
MM_CAMERA += com.qti.sensor.s5k3p9sx
...
MM_CAMERA += com.qti.actuator.dw9763
裝置樹
在驅動框架、編譯系統都準備就緒以後，就要實際結合硬體來進行修改了，這部分的工作主要以配置引腳等屬性為主。
路徑：vendor/qcom/proprietary/devicetree-4.19/qcom/camera
根據版本不同，目錄略有差異，但類似，例如
vendor/qcom/proprietary/camera-devicetree
camera-devicetree 這邊的dtsi檔案，配置的就是和camera上電相關的內容了， 修改了該目錄下的檔案後，我們需要編譯dtbo.img檔案來燒錄更新修改。
vendor/qcom/proprietary/camera-devicetree$ ls
bengal-camera.dtsi kona-camera-sensor-mtp.dtsi lito-camera.dtsi
bengal-camera-sensor-idp.dtsi kona-camera-sensor-qrd.dtsi lito-camera-sensor-cdp.dtsi
camera.dtsi
我們開啟需要編譯的dtsi檔案，看下里面的內容：
