staging: ipack: remove irq field in struct ipack_device.

2012-09-14T03:21:38Z

The field irq currently is identical to the slot number. It does not seem to have any real use. The number is written to hardware in ipoctal but it seems the value that is written does not matter.

Staging: ipack: move the responsibility to clear interrupts to the IPack devices.

2012-09-14T03:21:38Z

Now the IPack device acknowledges its own IRQ. Signed-off-by: Jens Taprogge Signed-off-by: Samuel Iglesias Gonsalvez Signed-off-by: Greg Kroah-Hartman

Staging: ipack: Add IPACK_INT_SPACE memory space.

2012-09-14T03:21:38Z

This will allow us to correctly access the IPack INT space. Signed-off-by: Jens Taprogge Signed-off-by: Samuel Iglesias Gonsalvez Signed-off-by: Greg Kroah-Hartman

staging: ipack/bridges/tpci200: Use endianess-aware types where applicable.

Staging: ipack: Let interrupts return irqreturn_t.

Staging: ipack/bridges/tpci200: move tpci200_free_irq() and tpci200_request_irq()

2012-09-12T16:56:01Z

Now, all the interrupt related functions are next to each other. Signed-off-by: Jens Taprogge Signed-off-by: Samuel Iglesias Gonsalvez Signed-off-by: Greg Kroah-Hartman

Staging: ipack/bridges/tpci200: More cleanups.

2012-09-12T16:56:01Z

Rename __tpci_request_irq() to tpci_enable_irq() and __tpci_free_irq() to tpci_disable_irq(). Change their second argument, move them above tpci200_interrupt(), and use tpci_disable_irq() in the latter Signed-off-by: Jens Taprogge Signed-off-by: Samuel Iglesias Gonsalvez Signed-off-by: Greg Kroah-Hartman

Staging: ipack/bridges/tpci200: Cleanup in tpci200_slot_irq() and tpci200_interrupt()

2012-09-12T16:56:01Z

Minor cleanup. No functional changes. Signed-off-by: Jens Taprogge Signed-off-by: Samuel Iglesias Gonsalvez Signed-off-by: Greg Kroah-Hartman

Staging: ipack/bridges/tpci200: Clean up interrupt handling.

2012-09-12T16:56:01Z

Previously the return value from tpci200_interrupt was not quite correct if a slot had caused an interrupt but no handler was instellalled: IRQ_NONE was returned. However in this case we react to the interrupt by disabling the IPack device interrupt. Basically there are two cases the code now distinguishes: - The tpci200 has raised an interrupt. We handle it and return IRQ_HANDLED. - Our device did not raise an interrupt. We return IRQ_NONE.
