Subject: [PATCH v2 00/18] genpd: Create a genpd directory to host genpd providers
Changes in v2:
- Added/updated commit messages to patch2 - > patch18.
- Fixed the build for amlogic
- Added a few tags for acks/reviewed by.
- Cc all platform/soc maintainers on the cover-letter and patch1.
- Updated the path to the git tree. The git is now created.
- Rebased on v6.5-rc1.
- Update the cover letter a bit.
There are currently ~60 users of the genpd provider interface, which
implementations are sprinkled across various subsystems. To help out with
maintenance and to gain a bit better control, let's create a new subsystem
(drivers/genpd) and move some of the providers from the soc directories in here.
Clearly some providers aren't really feasible to move - and that's perfectly
fine too. We don't need to keep all genpd providers together to improve the
situation, but keeping most of them would be nice, I think. At this point I
have walked through driver/soc and /arch/ - deferring others to later. Moreover,
I am intentionally leaving the Kconfig files in drivers/soc/, as I think it's
better to discuss what to with them separately.
Note that, the intention is also to host a git tree (it's not been created yet,
but should be quick if this seems reasonable to everybody), to collect and to
get the patches tested/integrated through the linux-next tree. Ideally this
should release some of the burden on the soc maintainers (Arnd/Olof/etc).
Note that, going forward - it's probably best to funnel this through the soc
tree (I can send a pull request if agreed) the I can take over in the next
release cycle at v6.6-rc1 and onwards. In that case, I will of course require
acks/reviews from the current platform/soc maintainers, hence the MAINTAINERS
are also being updated as a part of $subject series.
Does this make sense?
Kind regards
Ulf Hansson
