here comes the question:

Peter's patches should be applied only to the mainline development tree:

if I clone the git Daniel suggested I get errors:

error: patch failed: drivers/gpu/drm/i915/intel_display.c:5316
error: drivers/gpu/drm/i915/intel_display.c: patch does not apply

I also tried to reapply the patch after branching to drm-intel-fixes
but I got an error I don't know how to cope with:

$ git am 152705 152707 152708
previous rebase directory /home/alfonso/kernel/linux/.git/rebase-apply
still exists but mbox given.

for now I'm going on compiling mainline (I'll report asap), plus Peter's patches
but is there a chance to have Peter's patch for the drm-intel-fixes branch?

what am I missing when I use mainline? I ask this since I have two
separate issues...

in the meanline the patches were accepted:
$ git am 152705 152707 152708
Applying: drm/i915: specify vertical timings in frame units for
interlaced modes (gen3+)
Applying: drm/i915: allow interlaced mode output on the SDVO connector
Applying: drm/i915: allow interlaced mode output on the HDMI connector

thank you,
