Problem with MIPI camera on Xavier NX

Does Xavier NX have the ability to run mipi cameras by following settings ?
Based on the specification that it have two D-PHY 1.2 interface. Each csi interface have 2 lanes. It’s right?
I assume that the total bandwidth = 5Gbps (~ 625MB/s)

Resolution : 3840x2160
Pixel Format : YUY2 (YUV)
Frame Rate: 30 fps

I have one MIPI cameras (integrate with external bsp) that I am trying to use on my Xavier NX board. By using the Gstreamer pipeline to estimate the fps then it shows only 20 fps (~316MB/s). What are its limitations? (nx hardware, kernel core or v4l2 framework).

Have a try to boost the NVCSI/VI clocks to try.

sudo nvpmodel -m 0
sudo jetson_clocks

sudo su
echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked
cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate |tee /sys/kernel/debug/bpmp/debug/clk/vi/rate
cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate | tee  /sys/kernel/debug/bpmp/debug/clk/isp/rate
cat /sys/kernel/debug/bpmp/debug/clk/nvcsi/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate

Have you tried with the suggestions? Any result can be shared?
