programming sequence to access the hardware. The other boards supported
by this driver use simple register mapping. Including support for the
PCI-1760 in this driver just makes it harder to understand.

Separate out the PCI-1760 support into a new driver, adv_pci1760.

Clean up the new driver. The original code had a bunch of CamelCase and
other checkpatch.pl issues.

The code used to access the outgoing/incoming mailboxes was also a bit
awkward with the passing of the arrays for the outgoing and incoming
mailbox bytes. Replace them with two new functions that send a command
and return the feedback data from the command based on the programming
flow chart in the datasheet for the PCI-1760.

This subdevice is actually the 2 PWM outputs so the subdevice type
has been changed to COMEDI_SUBD_PWM.

The counter subdevice support was not complete in the original code.
They are also a bit strange since they are up counters connected to

So far, my patches tried to do equivalent conversions of the

how the devices get probed. In particular, the spi driver
no longer creates the netdev until the device is probed,
and I've removed the global wilc_sdio_func and wilc_spi_dev

variable that will eventually get passed through all functions

Whether the SDIO function uses an internal or external interrupt
should not be a compiletime decision but be determined at runtime.

This changes the code to pass a GPIO number from the init code
as early as possible, and leaves just one #ifdef WILC_SDIO_IRQ_GPIO
to preserve the previous behavior.

All other locations that check for the interrupt method are turned
into runtime checks based on the gpio number (>=0) or the interrupt
number (>0).

staging/wilc1000: use device pointer for phy creation

wilc_create_wiphy tries to get a pointer to a device from the
global wilc_sdio_func variable. This is a layering violation
and we can use the wilc_dev->dev pointer instead.

staging/wilc1000: pass io_type to wilc_netdev_init

In order to avoid some of the #ifdefs, this passes the io_type
and device pointer as an argument to wilc_netdev_init.

staging/wilc1000: unify device pointer

struct wilc has two pointers to store the device, one for sdio_func
and one for spi_device. By changing the pointer to a 'struct device',
we can simplify the logic and avoid a few #ifdefs.
