      drm/i915: Limit the watermark to at least 8 entries on gen2/3 · d6feb196
      Ville Syrjälä authored 
      830 is very unhappy of the watermark value is too low (indicating a very
high watermark in fact, ie. memory fetch will occur with an almost full
FIFO). Limit the watermark value to at least 8 cache lines.

That also matches the burst size we use on most platforms. BSpec seems
to indicate we should limit the watermark to 'burst size + 1'. But on
gen4 we already use a hardcoded 8 as the watermark value (as the spec
says we should), so just use 8 as the limit on gen2/3 as well.

      drm/i915: Fix DVO 2x clock enable on 830M · 1c4e0274
      Ville Syrjälä authored 
      The spec says:
"For the correct operation of the muxed DVO pins (GDEVSELB/ I2Cdata,
GIRDBY/I2CClk) and (GFRAMEB/DVI_Data, GTRDYB/DVI_Clk): Bit 31
(DPLL VCO Enable) and Bit 30 (2X Clock Enable) must be set to “1” in
both the DPLL A Control Register (06014h-06017h) and DPLL B Control
Register (06018h-0601Bh)."

The pipe A and B force quirks take care of DPLL_VCO_ENABLE, so we
just need a bit of special care to handle DPLL_DVO_2X_MODE.

v2: Recompute num_dvo_pipes on the spot, use PIPE_A/PIPE_B instead
    of pipe/!pipe for the register offsets in disable (Daniel)
    Add a comment about the ordering in enable and another one
    about filtering out the DVO 2x bit in state readout

      Commit "drm/rcar-du: Use struct videomode in platform data" touches board code
in arch/arm/mach-shmobile. There is, to the best of my knowledge, no risk of
conflict for v3.18. Simon, are you fine with getting those changes merged
through Dave's tree (and could you confirm that no conflict should occur) ?
