Hi, Venu.

I saw your patch about this from https://lkml.org/lkml/2012/7/18/232
because i doesn't subcribe linux-kernel ML yet.

The tps65090 mfd driver has two mfd_cells for "tps65090-pmic" and
"tps65090-regulator". I can find tps65090-regulator driver but cannot find
tps65090-pmic driver.

Is there any reason to exist two mfd_cells?

And one more question.

struct tps65090_platform_data {
        int irq_base;
        int num_subdevs;
        struct tps65090_subdev_info *subdevs;
}

This is  platform data struct for tps65090 mfd driver, but num_subdevs
and subdevs are not used in the mfd driver. How do you handle platform
data of tps65090 mfd driver and regulator driver?

Thanks.
