i am developing a linux kernel driver for a 4-CH AHD2.0 RX and 9-CH Audio Codec which is named nvp6124I .
below are few of its characteristics:
it digitizes and decodes ntsc/pal/comet/AHD1.0/AHD2.O video signal into digita video components
4ch analog video input and output 4ch digital signal, each channal has 8 data ports and a clk clock port
i want to submit the driver, but i have some problem on the below points:
1.I have write a v4l2-subdevice for this media codec,and it register /dev/videox sucsessed,but when i run a opencv captrue deom
I get a error information:select time_out.is there any body know what is the reason casused this,and how can i solve this problem.
2.just see the video interface ,i know i2c port can binding below the i2c node, but, how can i bind other data port and clock signal port
with device trees?
