Please remove the part in ()'s.

a) There's no need for it - we know what's in 'struct device' and b)
if 'struct platform_data' is removed from 'struct device' this comment
will become incorrect. Easy maintainability and all that ...

> + * @pdata: Platform data from DTS or board files

s/from/populated with data from

> + * @regmap_pmic: Regmap associated with PMIC's I2C address

Is there any reason for not using IRQ Domains?

> + * @irq: Generic IRQ number for device
> + * @irq_data: Runtime data structure for IRQ controller
> + * @ono: Power onoff IRQ number for s5m87xx

Perhaps consider a better name for this in a future patch.
