looks like SoC ID is not exported to sysfs for some reason.
This patch adds it!
This is mostly used by userspace libraries like SNPE.

What is SNPE?

Hmm I wasn't aware this driver was merged.

Snapdragon Neural Processing Engine. Pronounced "snap-e". Its
basically the framework someone goes through to run a neural network
on a Qualcomm mobile SoC. SNPE can utilize various hardware resources
such as the applications CPU, GPU, and dedicated compute resources
such as a NSP, if available. Its been around for over a year, and
much more information can be found by just doing a simple search since
SNPE is pretty much a unique search term currently.

I wouldn't mind if it was still spelled out instead of just as an
acronym. Who knows, a few years from now it may not be a unique acronym
and then taking the extra few seconds to write it out once would have
saved future effort.

Fair point.
