Tool/software:
While putiing the processor into deep sleep , it was told to do modprobe -rf ti_k3_dsp_remoteproc as this prevents from going to sleep , once I did this I was able to put into deep sleep , After waking up from sleep the dsp doesn't works , I was trying to stream my camera I was able to do run
gst-launch-1.0 v4l2src device=/dev/video3 ! video/x-bayer, width=1920, height=1080, format=grbg12 ! fakesink
but when I gave this command gives error as I think VISS uses dsp and i previously unloaded it.

Setting pipeline to NULL ...
So I want to know how to handle this , i want to use dsp once it wakes up from sleep , or any proper method to load again ti_k3_dsp_remoteproc .
I tried with modprobe ti_k3_dsp_remoteproc but still after this I was not able to stream.
