One thing that's new here in the core is SSC spread spectrum support (SSC) in the clk provider API. The idea is that DT authors will configure SSC for certain clks and they'll be configured at clk provider registration time or when a consumer device is probed, similar to how we handle assigned clk rates or parents. On the clk driver side we have Qualcomm adding almost half the diff because they add support for 4 different SoCs and then a long tail of other SoCs like Mediatek, Renesas, Rockchip, SpaceMiT, etc. add more SoC support this time around. Luckily it's mostly clk data for these new SoCs because the actual clk_ops are already there. Beyond the new drivers we get all the little fixups for more compilation coverage or usage of more modern APIs. That all looks normal. Finally, I kinda buried the lede, I'm bringing on Brian and Jerome to help out with maintaining the clk subsystem. The current working model is already semi-distributed in that silicon vendors typically take care of their drivers and send me pull requests but I'm becoming a bottleneck for new drivers and core framework review because this has become a 100% volunteer effort on my part. Mike is stepping down after all these years (thanks Mike!) and that jump started the conversation around finding co-maintainers. Brian and Jerome have graciously offered to help me with the work load, meaning in the future they'll be sending pull requests and committing directly to the clk.git tree. They've both been around on the list for a while, I've met them both in person, and they've been making changes to the core clk framework along with helping review patches so I'm pretty confident this will work well.

Similarly: a call to pwrseq_power_off() does not have to result in an actual powering off of resources: there may still be other users that requested a power-on before. We will also introduce the concept of "non-controllable" pwrseq targets soon which further increases the disconnect between the naming convention and the actual semantics. What consumers of pwrseq descriptors actually do is: they *vote* for a powering on of a given target or retract that vote. These operations could be called get/put in line with runtime PM but this could become confusing since we already provide pwrseq_get/put() for a different purpose. pwrseq_vote_on/off() also have been rejected as unusual in the tree. Change the name of the two functions to pwrseq_enable/disable() which better reflects their purpose and semantics and also mirrors other enable-counted resources like regulators and clocks. No functional change intended. If at any point users need to know *when* the exact power event happens, we can provide that information in the form of a notifier.
