BT656 camera driver example

[smzahraee]

I am trying to write a b656 camera driver.
Is there any working example camera driver in your camera drivers that you tested?
I wonder how to config device tree and driver configuration to enable V4L2_MBUS_BT656
good luck

Sorry, we have not tested the DVP camera driver and we are unable to guide you on how to configure the device tree and driver at this time.
But usually you can find linux drivers and tutorials for the corresponding camera or seek help from the camera vendor.

No Problem.
There is a "Rockchip Driver Guide VI v1.0.8" document, In that document there are some guides on running dvp interface.
but I could not find the right kernel for that document.
could you guide me how I can find that kernel to check?
Thanks

but I could not find the right kernel for that document.

I'm not sure about your question. Do you mean the driver?

I am searching for the source code corresponding to the specified kernel version mentioned in the document.
The document lists some clock names that I was unable to locate in your kernel source code.

For instance, I cannot determine which clock to use for the DVP. In a CSI camera, the clock is specified as clocks = <&cru MCLK_REF_MIPI0>;, but the appropriate clock for the DVP remains unclear. I came across CLK_VICAP_M0, but I am unsure if it is the correct choice.
