Subject: Re: [PATCH v6 09/27] dt-bindings: clock: mediatek: Describe MT8196 clock controllers

> Introduce binding documentation for system clocks, functional clocks,
> and PEXTP0/1 and UFS reset controllers on MediaTek MT8196.
> 
> This binding also includes a handle to the hardware voter, a
> fixed-function MCU designed to aggregate votes from the application
> processor and other remote processors to manage clocks and power
> domains.
> 
> The HWV on MT8196/MT6991 is incomplete and requires software to manually
> enable power supplies, parent clocks, and FENC, as well as write to both
> the HWV MMIO and the controller registers.
> Because of these constraints, the HWV cannot be modeled using generic
> clock, power domain, or interconnect APIs. Instead, a custom phandle is
> exceptionally used to provide direct, syscon-like register access to
> drivers.
