Hi
I'm looking for a way to turn the hdmi output on and off without rebooting.
I've seen some ways to disable it in the device tree or pass parameters to the kernel at boot time but nothing that will allow me to turn it off completely and then turn it back on without rebooting my system.
I need it to do power and electromagnetic tests, so the bus has to be really turned off with nothing running on it.
Do you have a clue or an idea?
Chip IMX8MDQLQRM
Kernel 4.19.35
Thanks.
