returns as soon as it finds any constraint that doesn't allow the
call to succeed.

4.2.3 pci_enable_msi_block_auto

int pci_enable_msi_block_auto(struct pci_dev *dev, unsigned int *count)

This variation on pci_enable_msi() call allows a device driver to request
the maximum possible number of MSIs. The MSI specification only allows
interrupts to be allocated in powers of two, up to a maximum of 2^5 (32).

If this function returns a positive number, it indicates that it has
succeeded and the returned value is the number of allocated interrupts. In
this case, the function enables MSI on this device and updates dev->irq to
be the lowest of the new interrupts assigned to it. The other interrupts
assigned to the device are in the range dev->irq to dev->irq + returned
value - 1.

If this function returns a negative number, it indicates an error and
the driver should not attempt to request any more MSI interrupts for
this device.

If the device driver needs to know the number of interrupts the device
supports it can pass the pointer count where that number is stored. The
device driver must decide what action to take if pci_enable_msi_block_auto()
succeeds, but returns a value less than the number of interrupts supported.
If the device driver does not need to know the number of interrupts
supported, it can set the pointer count to NULL.

4.2.4 pci_disable_msi
4.2.3 pci_disable_msi

void pci_disable_msi(struct pci_dev *dev)

This function should be used to undo the effect of pci_enable_msi() or
pci_enable_msi_block() or pci_enable_msi_block_auto(). Calling it restores
dev->irq to the pin-based interrupt number and frees the previously
allocated message signaled interrupt(s). The interrupt may subsequently be
assigned to another device, so drivers should not cache the value of
dev->irq.

interrupt number and frees the previously allocated message signaled
interrupt(s). The interrupt may subsequently be assigned to another
device, so drivers should not cache the value of dev->irq.

Before calling this function, a device driver must always call free_irq()
on any interrupt for which it previously called request_irq().

__devinit Device initialization code.
Identical to __init if the kernel is not compiled
with CONFIG_HOTPLUG, normal function otherwise.
__devexit The same for __exit.

Tips on when/where to use the above attributes:
o The module_init()/module_exit() functions (and all
initialization functions called _only_ from these)
should be marked __init/__exit.

o Do not mark the struct pci_driver.

o The ID table array should be marked __devinitconst; this is done
automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE().

o The probe() and remove() functions should be marked __devinit
and __devexit respectively. All initialization functions
exclusively called by the probe() routine, can be marked __devinit.
Ditto for remove() and __devexit.

o If mydriver_remove() is marked with __devexit(), then all address
references to mydriver_remove must use __devexit_p(mydriver_remove)
(in the struct pci_driver declaration for example).
__devexit_p() will generate the function name _or_ NULL if the
function will be discarded. For an example, see drivers/net/tg3.c.

o Do NOT mark a function if you are not sure which mark to use.
Better to not mark the function than mark the function wrong.

Driver a GPIO line that can be used to turn the power off.

The driver supports both level triggered and edge triggered power off.
At driver load time, the driver will request the given gpio line and
install a pm_power_off handler. If the optional properties 'input' is
not found, the GPIO line will be driven in the inactive
state. Otherwise its configured as an input.

When the pm_power_off is called, the gpio is configured as an output,
and drive active, so triggering a level triggered power off
condition. This will also cause an inactive->active edge condition, so
triggering positive edge triggered power off. After a delay of 100ms,
the GPIO is set to inactive, thus causing an active->inactive edge,
triggering negative edge triggered power off. After another 100ms
delay the GPIO is driver active again. If the power is still on and
the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.
