The adjustead_mode crtc_ timings are what we will program into the hardware,
so it's those timings we should be looking practically everywhere.
The normal and crtc_ timings should differ only when stere doubling is
used. In that case the normal timings are the orignal non-doubled
timigns, and crtc_ timings are the doubled timings used by the hardware.
The only case where we continue to look at the normal timings is when we
pass the adjusted_mode to drm_match_{cea,hdmi}_mode() to find the VIC.
drm_edid keeps the modes aronund in the non-double form only, so it
needs the non-double timings to match against.
Done with sed
's/adjusted_mode->\([vhVH]\)/adjusted_mode->crtc_\1/g'
's/adjusted_mode->clock/adjusted_mode->crtc_clock/g'

Another interesting criteria to work dmc as expected is pw1 to be
enabled by driver and dmc will shut it off in its execution
sequence. If already disabled by driver dmc will get confuse and
behave differently than expected found during pc10 entry issue
for skl.
So berfore we disable power-well 1, added check if dmc firmware is
present and driver will not disable power well 1, but for any reason
if firmware is not present of failed to load we can shut off the
power well 1 which will save some power.
As skl is currently fully dependent on dmc to go in lowest possible
power state (dc6) but the same is not applicable for bxt. Display
engine can enter into dc9 without dmc, hence unblocking disable call.

Dmc will restore the csr program except DC9, cold boot,
warm reset, PCI function level reset, and hibernate/suspend.
intel_csr_load_program() function is used to load the firmware
data from kernel memory to csr address space.
All values of csr address space will be zero if it got reset and
the first byte of csr program is always a non-zero if firmware
is loaded successfuly. Based on hardware status will load the
firmware.
Without this condition check if we overwrite the firmware data the
counters exposed for dc5/dc6 (help for debugging) will be nullified.
Note: Above commit message seems to be confused and the real problem
apparently going on is that for suspend-to-idle and system standby the
firmware survives (it's like runtime pm), but it doesn't for
suspend-to-mem and hibernate-to-disk. All the other talking about DC9
and pci reset are irrelevant for the path touched here (only driver
load and system resume functions) and might not be true statements.

->load is deprecated, bus functions are deprecated and everyone
should use drm_dev_alloc®ister.
So update the .tmpl (and pull a bunch of the overview docs into the
sourcecode to increase chances that it'll stay in sync in the future)
and add notes to functions which are deprecated. I didn't bother to
clean up and document the unload sequence similarly since that one is
still a bit a mess: drm_dev_unregister does way too much,
drm_unplug_dev does what _unregister should be doing but then has the
complication of promising something it doesn't actually do (it doesn't
unplug existing open fds for instance, only prevents new ones).
Motivated since I don't want to hunt every new driver for usage of
drm_platform_init any more ;-)
