From mboxrd@z Thu Jan 1 00:00:00 1970 From: Darwin Rambo Date: Fri, 13 Dec 2013 12:57:26 -0800 Subject: [U-Boot] [PATCH] i2c: Fix i2c speed command Message-ID: <1386968246-20386-1-git-send-email-drambo@broadcom.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This corrects i2c core to interpret the value returned by i2c_set_bus_speed as a success indicator rather than the actual speed that was set. When i2c_set_bus_speed returns a failure code, the speed is unknown so the adapter speed is set to zero.
