I suggest we add it to include/linux/mfd/motorola-cpcap.h:

static inline int cpcap_get_irq_status(struct device *dev,
				       struct regmap *regmap,
				       int irq,
				       u16 *status);

Or do you guys have better ideas?

I'll be needing that for the USB PHY driver too for multiple
bits so we want to return the whole bank register in status.

We may want to change to do that later to avoid dependencies
or set up an immutable branch with just that change.

Other than that things work for me based on a quick test.

Regards,

Tony
