Function Documentation

int __devinit __pata_platform_probe	(	struct device *	dev,
		struct resource *	io_res,
		struct resource *	ctl_res,
		struct resource *	irq_res,
		unsigned int	ioport_shift,
		int	__pio_mask
	)

__pata_platform_probe - attach a platform interface : device : Resource representing I/O base : Resource representing CTL base : Resource representing IRQ and its flags : I/O port shift : PIO mask

Register a platform bus IDE interface. Such interfaces are PIO and we assume do not support IRQ sharing.

Platform devices are expected to contain at least 2 resources per port:

- I/O Base (IORESOURCE_IO or IORESOURCE_MEM)
- CTL Base (IORESOURCE_IO or IORESOURCE_MEM)

and optionally:

- IRQ      (IORESOURCE_IRQ)

If the base resources are both mem types, the ioremap() is handled here. For IORESOURCE_IO, it's assumed that there's no remapping necessary.

If no IRQ resource is present, PIO polling mode is used instead.

__pata_platform_remove - unplug a platform interface : device

A platform bus ATA device has been unplugged. Perform the needed cleanup. Also called on module unload for any active devices.
