Subject: [PATCH v3 00/27] Add support for MT8196 clock controllers
This patch series introduces support for the clock controllers on the
MediaTek MT8196 platform, following up on an earlier submission[1].
MT8196 uses a hardware voting mechanism to control some of the clock muxes
and gates, along with a fence register responsible for tracking PLL and mux
gate readiness. The series introduces support for these voting and fence
mechanisms, and includes drivers for all clock controllers on the platform.
[1] https://lore.kernel.org/all/20250307032942.10447-1-guangjie.song@mediatek.com/
Changes in v3:
- Removed duplication in clock parent lists in the topckgen, topckgen2, and vlpckgen drivers
- Added vlp_clk26m parent and index table for audio clocks in the vlpckgen driver
- Added APLL tuner initialization to the probe function of the vlpckgen driver
- Dropped the adsp driver
- Merged reset controller binding into the clock binding doc commit
- Dropped .owner entry from mfg driver
- Added R-b tags
