438b74a549 drm: Nuke fb->pixel_format 
Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.

Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

v2: Fix commit message (Laurent)
    Rebase due to earlier removal of many fb->pixel_format uses,
    including the 'fb->format = drm_format_info(fb->format->format);'
    snafu
v3: Adjusted the semantic patch a bit and regenerated due to code
    changes

81852b6abc drm/arcpgu: Add local 'fb' variables 
Add a local 'fb' variable to a few places to get rid of the
'crtc->primary->fb' stuff. Looks neater and helps me with my ppor
coccinelle skills later.

420382adf6 drm: Don't implement empty prepare_fb()/cleanup_fb() 
The plane .prepare_fb() and .cleanup_fb() helpers are optional, there's
no need to implement empty stubs, and no need to explicitly set the
function pointers to NULL either.

84d9a4a288 drm/arc: Actually bother with handling atomic events. 
The drm core has a nice ready-made helper for exactly the simple case
where it should fire on the next vblank.

Note that arming the vblank event in _begin is probably too early, and
might easily result in the vblank firing too early, before the new set
of planes are actually disabled. But that's kinda a minor issue
compared to just outright hanging userspace.

v2: Be more robust and either arm, when the CRTC is on, or just send
the event out right away.

v3: Just unconditionally send out the event directly, for safety -
arcpgu doesn't even have vblank support ...

ed4f885657 drm/arc: Nuke event_list 
This is just used for cleanup in preclose, and with the reworked event
handling code this is now done properly by the core.

Nuke it!

But it also shows that arc totally fails at sending out drm events for
flips. Next patch will hack that up.

v2: Rebase it!

51dacf2089 drm: Add support of ARC PGU display controller 
ARC PGU could be found on some development boards from Synopsys.
This is a simple byte streamer that reads data from a framebuffer
and sends data to the single encoder.
