From 1d31b58f648c4f754b23fed4d57acc941080e5ee Mon Sep 17 00:00:00 2001 From: Dirk Brandewie Date: Thu, 6 Oct 2011 11:26:30 -0700 Subject: i2c-designware: Move retriveving the clock speed out of core code. The clock frequecy supplied to the IP core is specific to a single instance of the driver. This patch makes it possible to have multiple Designware I2C cores in the system possibly running at different core frequencies.
