From 655b34a78adf60ef260981688837904208883ae9 Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Sat, 18 Apr 2009 22:34:01 -0500 Subject: i2c: Create common default i2c_[set|get]_bus_speed() functions New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions replace a number of architecture-specific implementations. Also, providing default functions will allow all boards to enable CONFIG_I2C_CMD_TREE. This was previously not possible since the tree-form of the i2c command provides the ability to display and modify the i2c bus speed which requires i2c_[set|get]_bus_speed() to be present.
