Function Documentation

int samsung_gpiolib_to_irq	(	struct gpio_chip *	chip,
		unsigned int	offset
	)

samsung_gpiolib_to_irq - convert gpio pin to irq number : The gpio chip that the pin belongs to. : The offset of the pin in the chip.

This helper returns the irq number calculated from the chip->irq_base and the provided offset.
