e81507acdc
are a couple patches to the core clk framework, but they're all basically
cleanups or debugging aids. The driver updates and new additions are dominated
in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
new drivers for various SoCs, and MediaTek gained a bunch of drivers for
MT8188. The MediaTek drivers are being modernized as well, so there are
updates all over that vendor's clk drivers. There's also a couple other new clk
drivers in here, for example the Starfive JH7110 SoC support is added.
Outside of the two major SoC vendors though, we have the usual collection of
non-critical fixes and cleanups to various clk drivers. It's good to see that
we're getting more cleanups and modernization patches. Maybe one day we'll be
able to properly split clk providers from clk consumers.
Core:
- Print an informational message before disabling unused clks
New Drivers:
- BCM63268 timer clock and reset controller
