Subject: Re: [PATCH RESEND v3 1/5] clk: Respect CLK_OPS_PARENT_ENABLE during recalc

Quoting Nicolas Frattaroli (2025-12-15 03:23:58)
> When CLK_OPS_PARENT_ENABLE was introduced, it guarded various clock
> operations, such as setting the rate or switching parents. However,
> another operation that can and often does touch actual hardware state is
> recalc_rate, which may also be affected by such a dependency.
> 
> Add parent enables/disables where the recalc_rate op is called directly.
