From 182bf92d19cf007c2d6b9a264107d6996ae9014f Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 20 Apr 2015 12:37:15 -0600 Subject: dm: i2c: Add an explicit test mode to the sandbox I2C driver At present this driver has a few test features. They are needed for running the driver model unit tests but are confusing and unnecessary if using sandbox at the command line. Add a flag to enable the test mode, and don't enable it by default.
