From 9ca1c5a4bf4105d6f2f2a46892495953dd3e2fec Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Wed, 6 Jun 2012 14:41:30 +0530 Subject: clk: cache parent clocks only for muxes caching parent clocks makes sense only when a clock has more than one parent (mux clocks). Avoid doing this for every other clock.
