FSL I2C driver programs the two I2C busses differently
The i2c_init() function in fsl_i2c.c programs the two I2C busses differently. The second I2C bus has its slave address programmed incorrectly and is missing a 5-us delay. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
