From 4bcfda09936da647b0a3b49d5dcb3c6c6ebb0395 Mon Sep 17 00:00:00 2001 From: "Tan, Raymond" Date: Wed, 3 Sep 2014 10:41:38 +0800 Subject: i2c: designware: add support of platform data to set I2C mode Use the platform data to set the clk_freq when there is no DT configuration available. The clk_freq in turn will determine the I2C speed mode. In Quark, there is currently no other configuration mechanism other than board files.

It went into a 16-bit flags field but was defined at (1 << 16). Since we have no 10-bit i2c devices on the other side of the tunnel on any known devices this was never a problem. Until we do it makes sense to remove this code. On the EC side the code to handle this flag was removed in .
