Subject: Re: [PATCH v4] clk: tegra: pll: Improve PLLM enable-state detection

Quoting Dmitry Osipenko (2020-07-09 10:20:57)
> Power Management Controller (PMC) can override the PLLM clock settings,
> including the enable-state. Although PMC could only act as a second level
> gate, meaning that PLLM needs to be enabled by the Clock and Reset
> Controller (CaR) anyways if we want it to be enabled. Hence, when PLLM is
> overridden by PMC, it needs to be enabled by CaR and ungated by PMC in
> order to be functional. Please note that this patch doesn't fix any known
> problem, and thus, it's merely a minor improvement.
