From e78feaaeeb9bbf78f961917d72d692802ac110e8 Mon Sep 17 00:00:00 2001 From: Graf Yang Date: Mon, 14 Sep 2009 04:41:00 +0000 Subject: [PATCH] Blackfin: swap clocksource ratings for gptimer/cycles The cycles clocksource is a higher resolution than the gptimer one, so make sure the ratings field reflects this.
