From c564e6ae6c5aa6e3995ff87ed4a32b4788ad5109 Mon Sep 17 00:00:00 2001 From: Daniel Silverstone Date: Fri, 13 Mar 2009 13:53:46 +0000 Subject: i2c-s3c2410: Simplify bus frequency calculation The platform data for the i2c-s3c2410 driver used to allow a min, max and desired frequency for the I2C bus. This patch reduces it to simply a desired frequency ceiling and corrects all the uses of the platform data appropriately. This means, for example, that on a system with a 66MHz fclk, a request for 100KHz will achieve 65KHz which is safe and acceptable, rather than 378KHz which it would have achieved without this change.
