ILK is the only platform that we consider "gen5" and SNB is the only
platform we consider "gen6." Add an IS_SANDYBRIDGE() macro and then
replace numeric platform tests for these two generations with direct
platform tests with the following Coccinelle semantic patch:
@@ expression dev_priv; @@
- IS_GEN(dev_priv, 5)
+ IS_IRONLAKE(dev_priv)
@@ expression dev_priv; @@
- IS_GEN(dev_priv, 6)
+ IS_SANDYBRIDGE(dev_priv)
@@ expression dev_priv; @@
- IS_GEN_RANGE(dev_priv, 5, 6)
+ IS_IRONLAKE(dev_priv) || IS_SANDYBRIDGE(dev_priv)
This will simplify our upcoming patches which eliminate INTEL_GEN()
usage in the display code.
v2:
- Reverse ilk/snb order for IS_GEN_RANGE conversion. (Ville)
- Rebase + regenerate from semantic patch

Move the g4x+ DP code into a new file. This will leave mostly
platform agnostic code in intel_dp.c. Well, the misplaced phy
test stuff pretty much ruins that, but let's squint real hard
for now.
v2: Add comment exlaining which platforms are covered (Daniel)
Leave intel_dp_unused_lane_mask() be since it is pretty generic

intel_display.c has some pps functions that belong to intel_pps.c. Move
them over.
While at it, refactor the duplicate intel_pps_init() in intel_display.c
into an orthogonal intel_pps_setup() in intel_pps.c, and call it earlier
in intel_modeset_init_nogem().

Once you realize there is no need to hold the pps mutex when calling
pps_init_timestamps() in intel_pps_init(), we can reuse
intel_pps_encoder_reset() which has the same code.
Since intel_dp_pps_init() is only called from one place now, move it
inline to remove one "init" function altogether.
Finally, remove some initialization from
vlv_initial_power_sequencer_setup() and do it in the caller to highlight
the similarity, not the difference, in the platforms.
v2: Fix comment (Anshuman)

There are a number of functions that "init" pps in various ways. Try to
find some more consistency in the naming.
Rename:
- intel_dp_init_panel_power_sequencer -> pps_init_delays
- intel_dp_init_panel_power_sequencer_registers -> pps_init_registers
- intel_dp_init_panel_power_timestamps -> pps_init_timestamps
as this is what the functions do. Skip the intel_ prefix here to
emphasize these are static and not exported.
No functional changes.

Add an "encoder reset" call to hide some more pps functions, and clean
up the callers. A minor functional change is not holding the pps lock
across the whole operation in intel_dp_encoder_reset, but instead doing
it in two steps.
v2: rename intel_pps_reinit to intel_pps_encoder_reset for clarity

In a long overdue refactoring, split out all panel sequencer code from
intel_dp.c to new intel_pps.[ch].
The first part is mostly just code movement as-is, without cleanups or
functional changes.
We need to add a vlv_get_dpll() helper to get at the vlv/chv dpll from
pps code.
v2: Rebase.
