This should probably refer to the standard (JEDEC JESD301). Also, I am not
sure if pmic50x0 is appropriate, since the standard refers to pmic5000 and
pmic5010, but does not cover pmic50[2-9]0.

You did not Cc any maintainers, but you Cc-ed 5 Amazon people. Great.

Drop unrelated Cc list and start using kernel tools for development.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument, so you will
not CC people just because they made one commit years ago). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.

Tools like b4 or scripts/get_maintainer.pl provide you proper list of
people, so fix your workflow. Tools might also fail if you work on some
ancient tree (don't, instead use mainline) or work on fork of kernel
(don't, instead use mainline). Just use b4 and everything should be
fine, although remember about 'b4 prep --auto-to-cc' if you added new
patches to the patchset.
