In case of runtime pinmuxing, the pin configuration would also be
required to be setup in some cases. pin_config_set() is suitable to be
called from the platform code. In case of runtime pinmuxing in driver
code, is there any way to set the pin config also at runtime in driver
code?

Thanks,
Thomas.
