Let me just check I understand this ...

.. so if I just need to change MUX to control GPIO in I/O mode, I need that API to the SC to do this ..?

Where is this document .. ? (why there is no link to official latest version to it in the chip's UG?)


JUST making sure I need "that" highly protected Mux to do this -->

This UG part does not say which mux it is !

... "IOMUX chapter",    where ,which .. ? There is sub-chapter / section on IOMUXD.  

Would be awesome if NXP does in-the-doc links to what they refer to.

@joanxie 

Sorry I thought that was clear from my original question / post. Processor is iMX8QM, and document is one referred by NXP's User Guide :

Please see "i.MX 8QuadMax Applications Processor Reference Manual".

So, which is this "System Controller API Reference Guide .. "?   Where is latest official version ..?

If I'm working with older NXP linux distro/release - 4.19.35 - do I have to use the SCFW archive version matching that specific Linux version / release , or should I use latest available of the SCFW..?

If so, is there official Repo with all the SCFW  archive files .. ? Is there official git repo to take latest source ..?
