Subject: [PATCH v2 0/3] nvmem: s32g-ocotp: Add driver for S32G OCOTP

This driver provides a way to access the On Chip One-Time Programmable
Controller (OCOTP) on the s32g chipset.  There are three versions of this
chip but they're compatible.

v2:
I have fixed everything that people pointed out about version 1.

Sorry, Rob and Krzysztof, for the problems with the device tree YAML
file.  I had an issue with my dtschema installation and it's fixed now.

I also screwed up the From headers in v1.  I called git format-patch
without passing the --from argument.  I've fixed my scripts so that
won't happen again.  I also messed up the Signed-off by lines in patch
1 and 2.  Sorry!

My other mistakes were from not being a familiar enough with the
subsystem and those are addressed as well.  Especially re-writing the
driver using keepouts cut down a lot of lines of code.  I've tested it
and the results are the same before and after.
