On my OMAP4 platform, I'm getting this error message repeated several times at boot:
omap_vc_i2c_init: I2C config for all channels must match. omap_vc_i2c_init: I2C config for all channels must match. This doesn't help identify what the problem is. Fix this message to be more informative: omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0). omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0). This allows us to identify which voltage domains have a problem, and what the I2C configuration state (a boolean, i2c_high_speed) setting being used actually is. omap4_iva_pmic and omap4_mpu_pmic both have it set true.
