Greetings all,

Was there a particular issue with this patch? I just realized that patches 1,2, and 5 were accepted but not 3 or 4.

Thanks,

-Nick Hawkins

It looks like you sent the patch to a lot of people, without addressing
anyone in particular. I certainly did not expect to pick it up like this.

When you resend the missing patches after 6.1-rc1, please send the
ones you want to be merged through the soc tree to:soc@kernel.org,
with reviewers and mailing lists on Cc, but nobody else as the
recipient.

For the SoC tree, I usually have separate branches for code
changes (usually just Kconfig and MAINTAINERS entries in case of
arm64), devicetree changes, defconfig changes and driver (typically
drivers/soc, but could be others that have no separate subsystem
maintainers), so ideally you send a set of patches or a pull request
for each such topic branch.
