From 6ae690da1b6315f34ab7312bd2a02d49a606ccf7 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Fri, 25 Feb 2011 15:39:29 -0700 Subject: [PATCH] OMAP2420: clock: use autoidle clkops for all autoidle-controllable interface clocks Mark each interface clock with a corresponding CM_AUTOIDLE bit with a clkops that has the allow_idle/deny_idle function pointers populated. This allows the OMAP clock framework to enable and disable autoidle for these clocks.
