[Intel-gfx] [PATCH 1/2] drm/i915/ddi: Don't frob the DP link scramble disabling flag

[Imre Deak]

According to BSpec this flag should not be changed while the DDI
function is enabled. On BDW+ the DP_TP_CTL register spec also states it
explicitly that the HW takes care of enabling/disabling the scrambling
for training patterns (and it must stay enabled for normal pixel
output). Assume that this HW automatic handling of scrambling is also
true for HSW.

BSpec: 8013, 7557, 50484

[Intel-gfx] [PATCH 2/2] drm/i915/ddi: Don't rewrite DDI_BUF_CTL reg during DP link training

[Imre Deak]

The driver enables the DDI function in the DDI_BUF_CTL register before
starting the link training and disables it when disabling the output. It
also gets disabled/re-enabled during link re-trainining.

Except of the above the value we program to the register (intel_dp->DP)
doesn't change, so no need to reprogram the register when changing the
link training patterns.

The only concern I had was the buf trans stuff for hsw/bdw/skl,
but looks like hsw_set_signal_levels() does everything we need.

Ok, I missed this part, will fix the commit message.

It is at least marked as debug only for hsw.
