Compare hash value before strcmp the full name to make clk_core_lookup faster. It make clk driver probe 30 percent faster on the platform have 1483 registered clks and average clock name length 20.Why is clk_core_lookup() a fast path for you?
Maybe because the Mediatek clock driver still does global clk name matching to resolve parents? _______________________________________________ Linux-mediatek mailing list Linux-mediatek@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-mediatek
