no /dev/media0 node appears on porting tc358749 mipi-csi

[chenfeng2016]

Hello,

I am porting the tc358749 module according to Linux 4.14.78_.0.0, kernel source /drivers/media/i2c/tc358743.c, but it doesn't work always, Under/dev/, we can only see /dev/video0, /dev/video1, but not /dev/media0,

Is the node of /dev/media0 necessary?

In addition, can you give some suggestions on how to porting  the tc358749 module on Android 9 on imx8mq;

thanks.

Hi feng

general way for porting is to look at exisitng mipi-csi drivers described in

sect.6.1.4 MIPI Camera Serial Interface (MIPI CSI) attached Linux Manual.

unit tests for testing :

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

Best regards
igor
