Axel Lin 19234cdda5 gpio: add MODULE_DEVICE_TABLE
The device table is required to load modules based on modaliases.

After adding MODULE_DEVICE_TABLE, below entries will be added to
modules.pcimap:

  pch_gpio             0x00008086 0x00008803 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0
  ml_ioh_gpio          0x000010db 0x0000802e 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0

Roland Stigge 6e20fb1805 drivers/gpio/pca953x.c: add a mutex to fix race condition
Add a mutex to register communication and handling.  Without the mutex,
GPIOs didn't switch as expected when toggled in a fast sequence of
status changes of multiple outputs.

Feng Tang 0766d20fdb langwell_gpio: modify EOI handling following change of kernel irq subsystem
Latest kernel has many changes in IRQ subsystem and its interfaces, like
adding "irq_eoi" for struct irq_chip, this patch is a follow up change
for that.

Also remove the unnecessary cast for a "void *".

Lennert Buytenhek 7f5db6a802 gpio: timbgpio: Fix up irq_data conversion breakage.
Commit a1f5f22adc ("gpio: timbgpio:
irq_data conversion") was slightly too enthusiastic in converting
timbgpio_irq() over to take an irq_data * argument instead of an
unsigned int irq argument, as it is a flow handler, which still take
IRQ numbers for now.  (And on top of that, it was using the wrong
accessors.)

This fixes it up, and seems to build without warnings.

Andres Salomon 1b912c1bca drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO functionality
This adds (well, re-adds actually) handling for events/IRQs through cs5535
GPIOs.  In the wild and wooly world of CS5535, setup_event() is for
assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the
pair to trigger IRQs.

These should really only be used in highly platform-specific drivers (such
as OLPC's DCON driver).  Sadly, because set_irq() uses MSRs, this causes
the driver to become X86-specific.
