It'd be pretty awesome if someone would care enough to port this all
properly to a class interface, perhaps submitting a command stream to
the core via a sw object on PFIFO (emulating how EVO works basically,
and also what nvidia have done forever..)..

But, this seems unlikely given how old this hardware is now, so, lets
just hide it away.

There's a heap of other bits and pieces laying around that are still
tangled.  I'll (re)move them in pieces.

Seen in the wild, don't have the hardware but this hacks things up to
treat it the same as GF119 for now.

Should be relatively safe, I'd be very surprised if anything major
changed outside of PGRAPH.  PGRAPH (3D etc) is disabled by default
however until it's confirmed working.

The page flip handler stores the page flip event pointer and then calls
drm_vblank_get() to enable the vblank interrupt. Due to the vblank off
delay, the vblank interrupt can be enabled in the hardware at that
point, even if the vblank reference count is equal to 0. If a vblank
interrupt is triggered between storing the event pointer and calling
drm_vblank_get(), the page flip completion handler will process the
event and call drm_vblank_put() with a reference count equal to 0. This
will result in a BUG_ON.

Fix the race condition by calling drm_vblank_get() before storing the
event pointer.

The tilcdc driver fails to be built as a module because of extraneous
MODULE_DEVICE_TABLE entries:

drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here

Since the entire point of these entries is to make the module autoload
when one of the devices is present, it's enough to keep the one entry
for "ti,am33xx-tilcdc", which should always be there if any of the
others are.

Backlight hotkeys weren't working before on certain cedartrail laptops.

The source of this problem is that the hotkeys' ASLE opregion interrupts
were simply ignored. Driver seemed to expect the interrupt to be
associated with a pipe, but it wasn't.

Accepting the ASLE interrupt without an associated pipe event flag fixes
the issue, the backlight code is called when needed, making the
brightness keys work properly.

[patrik: This patch affects irq handling on any netbook with opregion support]
