I got only this patch, no cover letter, no changelog. What happened here?

My bad, my scripts needs some more work :)

Will Cc you in the next version

+description:
+ The System Timer Module supports commonly required system and application
+ software timing functions. STM includes a 32-bit count-up timer and four
+ 32-bit compare channels with a separate interrupt source for each channel.
+ The timer is driven by the STM module clock divided by an 8-bit prescale
+ value.

Previously it was told to me there is no such soc as s32g but they are
named differently, e.g. s32g2. See other bindings.

Please consult internally and come with one unified approach to all NXP
bindings. Otherwise, if this is a real soc, fix this for top level
compatibles, because there is no s32g there either.

This applies to all NXP-related patches (which I am sure was previously
discussed on the lists).

What is confusing: previous compatible was correct and I did not ask to
change it.

Yeah, I think the answer is straightforward. It is s32g2 and s32g3, the two platforms having the STM. I'll will fix the compatibles.
