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. 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?
