From e1ca95e3a93c9a0392163a7a6791deda48b5eeca Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Thu, 13 Sep 2012 14:57:58 +0800 Subject: mtd: gpmi: do not set the default values for the extra clocks The default frequencies of the extra clocks are 200MHz. The current code sets the extra clocks to 44.5MHz. When i add the EDO feature to gpmi, i have to revert the extra clocks to 200MHz. So it is better that we do not set the default values for the extra clocks. The driver runs well even when we do not set the default values for extra clocks.
