Summary
This push request enables trigger output (TRGO) configuration for ST pwm instances via devictree.
Therefore the usage of the STM32 interconnect matrix is possible for pwm instances.
API remains unchanged.
What is changed
Alternatives
As described in #70097 an interconnect subsystem would solve the problem as well.
In comparison to a new subsystem this solution is more lightweight on code size and most init time.
Drawback is the hardware dependency to ST devices (but you have to know the hardware interconnect capabilities of your SoC in both cases to archive maximal performance).
