[PATCH v5 0/7] drm/mgag200: Implement VBLANK support

[Thomas Zimmermann]

Implement support for VBLANK events in mgag200.

Patches 1 to 5 prepare mgag200's modesetting code by renaming or
adding variables for various hardware fields. This makes the code
more readable and aligns it with the programming manuals for Matrox 
hardware.

Patch 6 implements support for VBLANK events. The patch has been
reviewed before at [1]. That old patchset never found its way into
the kernel, but the VBLANK support is still useful.

Patch 7 adds support for VBLANK timestamps.

v5:
- clear all interrupts before registering IRQ (Jocelyn)
- don't read from ICLEAR (Jocelyn)

v4:
- split off the patchset from an earlier series [1]
