From 92b7eb8ffc0741f1fd5fbd5458a466d608310442 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Thu, 22 Jun 2006 22:18:21 +0100 Subject: [ARM] 3628/1: S3C24XX: add get_rate call to struct clk Patch from Ben Dooks Add a get_rate call to allow an given clock to over-ride the clk_get_rate() call. This provides support for clocks which rely on division of their parent to correctly report their frequency when the parent can also change.
