This will be helpful for adding future platforms. It is better to keep
the information in the single point of truth (the table) instead of
duplicating it into the validity function.
While at it, add dev_priv parameter to the function, also to prepare for
adding future platform support.

Rename intel_gmbus_is_port_valid to intel_gmbus_is_valid_pin, and rename

Even though we only support atomic plane updates at the moment, we still
need to add an .atomic_get_property() entrypoint for connectors before
we allow the driver to flip on the DRIVER_ATOMIC bit. As soon as that
bit gets set, the DRM core will start adding atomic connector properties
(in addition to the plane properties we care about at the moment), so we
need to be able to handle the new way the DRM core will interact with
us.
For simplicity, we just lookup driver-specific connector properties in
the usual shadow array maintained by the core. Once we get real atomic
modeset support for crtc's and planes, this code should be re-written to
pull the data out of crtc/connector state structures.

We want to enable/test plane updates via the atomic interface, but as
soon as we flip DRIVER_ATOMIC on, the DRM core will take some atomic
codepaths to lookup properties during drmModeGetConnector() and some of
those codepaths unconditionally dereference connector->state
(specifically when looking up the CRTC ID property in
drm_atomic_connector_get_property()). Create a dummy connector state
for each connector at init time to ensure the DRM core doesn't try to
dereference a NULL connector->state. The actual connector properties
will never be updated or contain useful information, but since we're
doing this specifically for testing/debug of the plane operations (and
only when a specific kernel module option is given), that shouldn't
really matter.
Once we start creating connector states, the DRM core will want to be
able to clean them up for us. We also need to hook up the destruction
entrypoint to the core's helper.

On certain platforms pixel_multiplier is read out in
.get_pipe_config(), but it also gets used to calculate the
pixel clock in intel_sdvo_get_config(). If the pipe is disable
but some SDVO outputs are active, we may end up dividing by zero
in intel_sdvo_get_config().
To avoid the problem simply check for zero pixel_multiplier and skip
the division. Another attempt at fixing this involved populating
pixel_multiplier to 1 even for disabled pipes, but that triggered a
WARN because SDVO_CMD_GET_CLOCK_RATE_MULT command failed and thus
encoder_pixel_multiplier was left at zero and didn't match
pipe_config->pixel_multiplier.
The "divide by pixel_multiplier" operation got introduced here:

SDVO is used by both crtcs using the i9xx_ and the ironlake_
functions. For both cases there is nothing between the
encoder->mode_set and the encoder->pre_enable calls that touches the
hardware.
The vlv_ functions are different since they enable the pll before the
->pre_enable hook. But SDVO isn't supported on vlv platforms, so this
doesn't matter.
We've also already clean up all the sdvo state computation logic, all
relevant parts are already in the ->compute_config hook. So we can
just get rid of the ->mode_set hook by converting it to a ->pre_enable
hook.

Currently we allow encoders to indicate whether they can be part of a
cloned set with just one flag. That's not flexible enough to describe
the actual hardware capabilities. Instead make it a bitmask of encoder
types with which the current encoder can be cloned.
For now we set the bitmask to allow DVO+DVO and DVO+VGA, which should
match what the old boolean flag allowed. We will add some more cloning
options in the future.
Note that this patch also removes the encoder.possible_clones setting
from encoder setup code - we compute this dynamically.

Since
commit d9255d57147e1dbcebdf6670409c2fa0ac3609e6
Author: Paulo Zanoni <paulo.r.zanoni@intel.com>
Date: Thu Sep 26 20:05:59 2013 -0300
it became clear that we need to separate the unload sequence into two
parts:
1. remove all interfaces through which new operations on some object
(crtc, encoder, connector) can be started and make sure all pending
operations are completed
2. do the actual tear down of the internal representation of the above
objects
The above commit achieved this separation for connectors by splitting
out the sysfs removal part from the connector's destroy callback and
doing this removal before calling drm_mode_config_cleanup() which does
the actual tear-down of all the drm objects.
Since we'll have to customize the interface removal part for different
types of connectors in the upcoming patches, add a new unregister
callback and move the interface removal part to it.
No functional change.

For some reason, every single time I try to run module_reload
something tries to read the connector sysfs files. This happens
after we destroy the encoders and before we destroy the connectors, so
when the sysfs read triggers the connector detect() function,
intel_conector->encoder points to memory that was already freed.
The bad backtrace is just:

Now that adjusted_mode.clock no longer contains the pixel_multiplier, we
can kill the get_clock() callback and instead do the clock readout
in get_pipe_config().
Also i9xx_crtc_clock_get() can now extract the frequency of the PCH
DPLL, so use it to populate port_clock accurately for PCH encoders.
For DP in port A the encoder is still responsible for filling in
port_clock. The FDI adjusted_mode.clock extraction is kept in place
for some extra sanity checking, but we no longer need to pretend it's
also the port_clock.
In the encoder get_config() functions fill out adjusted_mode.clock
based on port_clock and other details such as the DP M/N values,
HDMI 12bpc and SDVO pixel_multiplier. For PCH encoders we will then
do an extra sanity check to make sure the dotclock we derived from
the FDI configuratiuon matches the one we derive from port_clock.
DVO doesn't exist on PCH platforms, so it doesn't need to anything
but assign adjusted_mode.clock=port_clock. And DDI is HSW only, so
none of the changes apply there.
v2: Use hdmi_reg color format to detect 12bpc HDMI case
v3: Set adjusted_mode.clock for LVDS too
v4: Rename ironlake_crtc_clock_get to ironlake_pch_clock_get,
eliminate the useless link_freq variable.

Some Poulsbo cards seem to incorrectly report
SDVO_CMD_STATUS_TARGET_NOT_SPECIFIED instead of
SDVO_CMD_STATUS_PENDING, which causes the display to be turned off.
This could also happen to i915.

It's what all callers (except for the destroy callback which is called
from drm core) actually want.

Try to decypher detection failures is a little tricker at the moment as
the only indicator of progress is when output_poll_execute() tells us
the result after the connector->detect() has run. This patch adds a
telltale to the start of each detect function so that we can track
progress and associate activity more clearly with each connector.

If intel_sdvo_get_value() fails here, val is unitialized and the cross
check will compare the pipe config multiplier with a bogus value.
Instead, only set encoder_pixel_multiplier when the sdvo command has
been successful. The cross check will compare the pipe config value with
0 otherwise.
v2: Do the cross check with the initial value of encoder_pixel_multiplier (0)
if the sdvo command fails (and thus keep the warning) (Daniel Vetter)

Now that we painstakingly track the shared pch dplls we can finally
implement pixel mutliplier readout support for pch ports, too.
v2: Undo the temporary hack to disable the sdvo pixel multiplier
cross-checking.

Last 3.11 feature pull. I have a few odds bits and pieces and fixes in my
queue, I'll sort them out later on to see what's for 3.11-fixes and what's
for 3.12. But nothing to hold this here up imo.
Highlights:
- more hangcheck work from Mika and Chris to prepare for arb robustness
- trickle feed fixes from Ville
- first parts of the shared pch pll rework, with some basic hw state
readout and cross-checking (this shuts up the confused pch pll refcount
WARN that Linus just recently forwarded)
- Haswell audio power well support from Wang Xingchao (alsa bits acked by
Takashi)
- some cleanups and asserts sprinkling around the plane/gamma enabling
sequence from Ville
- more gtt refactoring from Ben
- clear up the adjusted->mode vs. pixel clock vs. port clock confusion
- 30bpp support, this time for real hopefully

drm: Add probed modes in probe order
in drm-next. W simply need to add the vbt modes before edid modes, i.e. the
other way round than now.

We don't (yet) have proper pixel multiplier readout support on pch
split platforms, so the cross check will naturally fail.
v2: Fix spelling in the comment, spotted by Ville.
v3: Since the ordering constraint is pretty tricky between the crtc
get_pipe_config callback and the encoder->get_config callback add a
few comments about it. Prompted by a discussion with Chris Wilson on
irc about why this does work anywhere else than on i915g/gm.
