From b46226bdb5a1690756daf77c42bdec91194927b0 Mon Sep 17 00:00:00 2001 From: Dirk Eibach Date: Thu, 3 Jul 2014 09:28:18 +0200 Subject: i2c: IHS I2C master driver IHS I2C master support was merely a hack in the osd driver. Now it is a proper u-boot I2C framework driver, supporting the v2.00 master features.
