From 1a565cf07fa1be0a6d5cf30e87ee2d204e9753d3 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 27 Jan 2012 20:43:14 +0900 Subject: [PATCH] sh: cpufreq: notify about rate rounding fallback. The general case for platforms that support the clock framework fully will be rate table rounding, while others will have to fall back on much coarser general rate rounding. Notify about it during boot so the limited functionality for the given subtype is appropriately noted.
