About serdes_pix_clk_hz and mipi-rate in dts

Hi,
I have some questions about this formula

image

  1. What does the “deserializer output data rate in hertz” in the formula mean? How can I find out the value of this parameter?
  2. Does the “number of CSI lanes” in the formula refer to the number of lanes used, or does it mean all of them?For example, if the mipi is 2*4, but the sensor output is 2 lanes, about 288MHZ, yuv422(8bit). should I use that number to bring into the formula for calculation? And how do I calculate it using the formula?

thanks.

Doesn’t see this in default device tree.
You may need to check the kernel driver to known the detail.

Thanks

Hi,
I checked and re-edited. Please help with the answer.

Thanks.

Have check the programing guide for the detail of serdes_pix_clk_hz.

Yes, that’s what I found here, so please explain what deserializer output data rate in hertz means

Suppose It’s the same with pix_clk_hz but may greater than it able 115%.
