Laurent Pinchart	138b87fa43	drm: vblank: Fix vblank timestamp update ... Commit 3fcdcb2709 ("drm/vblank: Switch to bool in_vblank_irq in get_vblank_timestamp") inverted a condition by mistake that resulted in vblank timestamps always being 0 on hardware without a vblank counter. Fix it.

Daniel Vetter	16584b2045	drm/doc: Polish irq helper documentation ... Pull a (much shorter) overview into drm_irq.c, and instead put the callback documentation into in-line comments in drm_drv.h. v2: Move the include stanzas back to the split-up patch (Stefan).

Daniel Vetter	3ed4351a83	drm: Extract drm_vblank.[hc] ... drm_irq.c contains both the irq helper library (optional) and the vblank support (optional, but part of the modeset uapi, and doesn't require the use of the irq helpers at all. Split this up for more clarity of the scope of the individual bits. v2: Move misplaced hunks to this patch (Stefan).
