From: Lee Jones <[email protected]> Date: Wed, 13 Jun 2012 16:21:14 +0100 Subject: [PATCH 2/3] ARM: ux500: Add i2c configurations to the Device Tree for DB8500 based devices
For correct operation of the i2c-nomadik driver, it requires some information surrounding clock-frequencies, delay times and thresholds. Here we apply those configurations to be used when a platform is booted via the device Tree.
