These patches add support for the clock and power controllers
of MediaTek's new SoC, MT8189. With these changes,
other modules can easily manage clock and power resources
using standard Linux APIs, such as the Common Clock Framework (CCF)
and pm_runtime on MT8189 platform.
Irving-ch Lin (4):
dt-bindings: clock: mediatek: Add MT8189 clock definitions
dt-bindings: power: mediatek: Add MT8189 power domain definitions
clk: mediatek: Add clock drivers for MT8189 SoC
pmdomain: mediatek: Add power domain driver for MT8189 SoC

Nothing here nor in cover letter. No changes, so you did not fix any of the bugs you had last time? Why aren't you using b4 to submit patches which would handle this?

Don't do this, don't add the consumers. Drop. The binding did not improve, so I am not doing full review. Please go through writing bindings or tutorials/presentations explaining this, so we won't need to repeat same comments.
