[PATCH 00/14] drm: Some more vblank timestampi changes

[ville.syrjala at linux.intel.com]

So I took another look at the vblank timestamping code, and got a bit
excited. The result is this patchset.

Summary of changes:
- kill crtc->hwmode dependency
- eliminate a bunch of 64bit math
- fix timestamps for stereo and interlaced modes (on i915 at least)
- move the "early vbl irq" hack into radeon code
- add a similar hack to i915, but make it as finely targeted
  as possibly to minimize the chance of accidentally
  applying it in the wrong place

The s/clock/crtc_clock change could use some radeon people to verify
whether changing radeon_atom_get_tv_timings() is enough to make
crtc_clock always populated.

This series applies on top of Mario's
"Vblank timestamping improvements/fixes for Linux drm." series.

Ville Syrjälä (14):
      drm: Pass the display mode to drm_calc_timestamping_constants()
      drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos()
      drm/i915: Kill hwmode save/restore
      drm/i915: Call drm_calc_timestamping_constants() earlier
      drm: Improve drm_calc_timestamping_constants() documentation
      drm: Simplify the math in drm_calc_timestamping_constants()
      drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings()
      drm: Use crtc_clock in drm_calc_timestamping_constants()
      drm: Change {pixel,line,frame}dur_ns from s64 to int
      drm/i915: Fix scanoutpos calculations for interlaced modes
      drm: Fix vblank timestamping constants for interlaced modes
      drm: Pass 'flags' from the caller to .get_scanout_position()
      drm/radeon: Move the early vblank IRQ fixup to radeon_get_crtc_scanoutpos()
      drm/i915: Add a kludge for DSL incrementing too late and ISR not working
