[PATCH 06/16] ARM: omap: fix uninformative vc/i2c configuration error message

[Tony Lindgren]

* Russell King - ARM Linux <linux at arm.linux.org.uk> [120208 08:06]:
> 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.
