Hello,
I am writing the device tree for our custom board, which uses an nRF9160 SiP. This approach to configuring the hardware
is new to me, since my experience is with micro-controllers where the hardware is configured at runtime.
With the device trees, once a set of pins is configured for a given functionality (say serial port or SPI) is it possible to change them
at runtime for another functionality ?
For instance, two pins are configured as Tx and Rx of a serial port, but for testing we would like to be able to at runtime to
change them to I/O pins and control them.
