Aidan MacDonald ca54d06fca clk: ingenic: Mark critical clocks in Ingenic SoCs ... Consider CPU, L2 cache, and memory clocks as critical to prevent them -- and the parent clocks -- from being automatically gated, since nothing calls clk_get() on these clocks. Gating the CPU clock hangs the processor, and gating memory makes external DRAM inaccessible. Normal kernel code can't hope to deal with either situation so those clocks have to be critical. The L2 cache is required only if caches are running, and could be gated if the kernel takes care to flush and disable caches before gating the clock. There's no mechanism to do this, and probably no reason to do it, so it's simpler to mark the L2 cache as critical.
