(

pm8xxx_get_irq_stat

)

int pm8xxx_get_irq_stat	(	struct pm_irq_chip *	chip,
		int	irq
	)

pm8xxx_get_irq_stat - get the status of the irq line : pointer to identify a pmic irq controller : the irq number

The pm8xxx gpio and mpp rely on the interrupt block to read the values on their pins. This function is to facilitate reading the status of a gpio or an mpp line. The caller has to convert the gpio number to irq number.

RETURNS: an int indicating the value read on that line
