Subject: Re: [PATCH v5 6/8] clk: tegra20: Turn EMC clock gate into divider

Quoting Dmitry Osipenko (2018-07-24 09:42:19)
> Kernel should never gate the EMC clock as it causes immediate lockup, so
> removing clk-gate functionality doesn't affect anything. Turning EMC clk
> gate into divider allows to implement glitch-less EMC scaling, avoiding
> reparenting to a backup clock.
