i.mx8mq tvin(adv7282M)

[liyu1]

Hello everyone ！

      I have a custom board。

      my hardware:  i.mx8mq 

      OS： android 9_1.0.0

      The question I want to ask is： Is there any relevant document about  i.mx8mq Android 9 TVin？

       Now I register the name of the device driver of adv7282 as adv7180 _decoder

      static const struct i2c_device_id adv7282m_id[] = {
824 {"adv7180_decoder", 0},
825 };
826
827 MODULE_DEVICE_TABLE(i2c, adv7282m_id);
828
829 static const struct of_device_id adv7282m_of_match[] = {
830 { .compatible = "adv,adv7180_decoder" },
831 { /* sentinel */ }
832 };
833
834 static struct i2c_driver adv7282m_i2c_driver = {
835 .driver = {
836 .owner = THIS_MODULE,
837 .name = "adv7180_decoder",
838 .of_match_table = of_match_ptr(adv7282m_of_match),
839 },
840 .probe = adv7282m_probe,
841 .remove = adv7282m_remove,
842 .id_table = adv7282m_id,
843 };
844
845 module_i2c_driver(adv7282m_i2c_driver);
846
847 MODULE_AUTHOR("NXP Semiconductor, Inc.");
848 MODULE_DESCRIPTION("adv7282m Video Decoder Driver");
849 MODULE_LICENSE("GPL");
850 MODULE_VERSION("1.0");
851 MODULE_ALIAS("CSI");

HAL print is :

01-01 00:00:45.768 2934 2934 I FslCameraHAL: enumSensorSet

01-01 00:00:45.769 2934 2934 I FslCameraHAL: camera number is 1

Now I have successfully registered the adv7282m driver, and the driver name is adv7180_decoder,

But the HAL layer creates the ov5640 object。

My init.rc:

setprop camera.disable_zsl_mode 1
67 setprop back_camera_name mx6s-csi
68 setprop back_camera_orient 0
69 setprop front_camera_name uvc
70 setprop front_camera_orient 0

I want to know what else I need to change？

Hi li

I am afraid adv7282m is not supported in nxp software bsps and not aware

of relevant documentation. As suggestion one can look at efforts on

iMX8M MIPI-CSI 4-lane configuration 

and driver sources, check function csi_tvdec_enable()
mx6s_capture.c\capture\mxc\platform\media\drivers - linux-imx - i.MX Linux kernel 

unit tests:

mxc_v4l2_test\test - imx-test - i.MX Driver Test Application Software 

Best regards
igor

@igorpadykov ：

    Thank you for your reply ！

    I have implemented the driver of adv7282m, refer to adv7180,  But the Android Hal layer，I doesn't know how to modify it ， The object created by default is ov5640  ： 

     log  :       

 01-01 00:00:45.769 2934 2934 I FslCameraHAL: index:1, propName:uvc
01-01 00:00:45.769 2934 2934 I FslCameraHAL: matchNodeName
01-01 00:00:45.769 2934 2934 I FslCameraHAL: create id:0 5640-csi-8mq device
01-01 00:00:45.769 2934 2934 I FslCameraHAL: Camera:0: new camera device
01-01 00:00:45.769 2934 2934 I FslCameraHAL: camera number is 1

     But my driver name is adv7180_decoder !   Does init.rc need to be changed ？

     setprop back_camera_name mx6s-csi
     setprop back_camera_orient 0
     setprop front_camera_name uvc

     setprop front_camera_orient 0

    Attachment: drive of adv7282m， Thanks！
