[PATCH 0/5] Haswell watermarks

[Paulo Zanoni <przanoni@gmail.com>]

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

Hi

This series is a new version of "drm/i915: replace snb_update_wm with
haswell_update_wm on HSW". Ville asked to split the series into smaller patches,
so here they are. I also implemented the other suggestions made by Ville.

After this series, the only thing missing for correctness of the Haswell
watermark register values will be to use the correct mode clock when calculating
linetime watermarks. I had a patch for this, but Daniel suggested to wait until
we merge "drm/i915: store adjust dotclock in adjustede_mode->clock". I can
already see us reaching PC7 state with this series on eDP 1920x1080 with
138.78MHz pixel clock.

Thanks,
Paulo
