Chon Ming Lee 44f37d1f52 drm/i915/chv: Pipe select change for DP and HDMI
With additional of pipe C, current 1 bit registers for pipe select
for HDMI and DP are no longer able to gather for 3 pipes. As a result,
new bits location in the same registers are added.

For HDMI, VLV uses bit 30, CHV uses bit 24-25.

For DP, VLV uses bit 30, CHV uses bit 16-17.

Ville Syrjälä 40478455fe drm/i915: Allow user modes to exceed DVI 165MHz limit
In commit
 commit 6375b768a9
 Author: Ville Syrjälä <ville.syrjala@linux.intel.com>
 Date:   Mon Mar 3 11:33:36 2014 +0200

    drm/i915: Reject >165MHz modes w/ DVI monitors

the driver started to filter out display modes which exceed the
single-link DVI 165Mz dotclock limits when the monitor doesn't report
itself as being HDMI compliant. The intent was to filter out all
EDID derived modes that require dual-link DVI to operate since we
don't support dual-link.

However the patch went a bit too far and also causes the driver to reject
such modes even when specified by the user. Normally we don't check the
sink limitations when setting a mode from the user. This allows the user
to specify any mode whether the sink reports to support it or not. This
can be useful since often the sinks support more modes than they report
in the EDID.

So relax the checks a bit, and apply the single-link DVI dotclock limit
only when filtering the mode list, and ignore the limit when setting
a user specified mode.

Ville Syrjälä c6f1495d4c drm/i915: Allow HDMI+HDMI cloning on g4x
BSpec is a bit unclear whether HDMI+HDMI cloning should work on g4x.
Tests on real hardware say that it does. Since g4x can't send
infoframes to more than one HDMI port anyway, we don't lose anything
by allow it.

For PCH platforms BSpec explicitly forbids HDMI+HDMI cloning.

Whether HDMI+HDMI cloning might also work on VLV is a bit unclear, but
since we'd at least lose the capability of sending infoframes to more
than one cloned HDMI port, it doesn't seem like a good idea to allow it.

Ville Syrjälä bc079e8b16 drm/i915: Make encoder cloning more flexible
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.

Imre Deak 6d129beac7 drm/i915: check port power domain when reading the encoder hw state

domain for that port is on before reading out the encoder HW state.

since all those just call the corresponding encoder get_hw_state
handler, which checks - after this change - for all power domains
the connector needs.

Imre Deak 4932e2c3c7 drm/i915: add unregister callback to connector
Since

commit d9255d5714
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.

Chon Ming Lee ab3c759a04 drm/i915/vlv: Rename VLV DPIO register to be more structure to match configdb document.
Some VLV PHY/PLL DPIO registers have group/lane/channel access.  Current
DPIO register definition doesn't have a structure way to break them
down. As a result it is not easy to match the PHY/PLL registers with the
configdb document.  Rename those registers based on the configdb for easy
cross references, and without the need to check the offset in the header
file.

New format is as following.

<platform name>_<DPIO component><optional lane #>_DW<dword # in the
doc>_<optional channel #>

For example,

VLV_PCS_DW0 - Group access to PCS for lane 0 to 3 for PCS DWORD 0.
VLV_PCS01_DW0_CH0 - PCS access to lane 0/1, channel 0 for PCS DWORD 0.

Another example is

VLV_TX_DW0 - Group access to TX lane 0 to 3 for TX DWORD 0
VLV_TX0_DW0 - Refer to TX Lane 0 access only for TX DWORD 0.

There is no functional change on this patch.

v2: Rebase based on previous patch change.
v3: There may be configdb different version that document the start DW
differently. Add a comment to clarify.  Fix up some mismatch start DW
for second PLL block. (Ville)

But if you add tons of memory checking debug options to your Kernel
you'll also see:

Ville Syrjälä 18442d0878 drm/i915: Fix port_clock and adjusted_mode.clock readout all over
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.

Jani Nikula b76cf76bfa drm/i915: rearrange vlv hdmi enable and pre_enable callbacks
VLV wants encoder enabling before the pipe is up. This is currently
achieved through calling the ->enable callback early, right after the
->pre_enable callback, in valleyview_crtc_enable(). This loses both the
distinction between ->pre_enable and ->enable on VLV and the possibility
to use a hook at the end of the modeset sequence.

Rearrange the HDMI callbacks to make it possible to move ->enable call
later. Basically do everything in ->pre_enable on VLV, and make ->enable
a NOP.

There should be no functional changes.

v2: Rebase.

    drm/i915: fixup 12bpc hdmi dotclock handling

I've errornously claimed that we don't yet support the hdmi 1.4
dotclocks > 225 MHz on Haswell. But a bug report and a closer look at
the wrpll table showed that we've supported port clocks up to 300MHz.

With the new code to dynamically compute wrpll limits we should have
no issues going up to the full 340 MHz range of hdmi 1.4, so let's
just use that to fix this regression. That'll allow 4k over hdmi for
free!

v2: Drop the random hunk that somehow slipped in.

v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also
patch up the mode filtering. To do so extract the dotclock limits into
a little helper function.

v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi
1.3), apparently hw is not required to be able to drive the highest
dotclocks. Suggested by Damien.

Daniel Vetter ff9a6750ac drm/i915: store adjusted dotclock in adjusted_mode->clock
... not the port clock. This allows us to kill the funny semantics
around pixel_target_clock.

Since the dpll code still needs the real port clock, add a new
port_clock field to the pipe configuration. Handling the default case
for that one is a bit tricky, since encoders might not consistently
overwrite it when retrying the crtc/encoder bw arbitrage step in the
compute config stage. Hence we need to always clear port_clock and
update it again if the encoder hasn't put in something more specific.
This can't be done in one step since the encoder might want to adjust
the mode first.

I was a bit on the fence whether I should subsume the pixel multiplier
handling into the port_clock, too. But then I decided against this
since it's on an abstract level still the dotclock of the adjusted
mode, and only our hw makes it a bit special due to the separate pixel
mulitplier setting (which requires that the dpll runs at the
non-multiplied dotclock).

So after this patch the adjusted_mode accurately describes the mode we
feed into the port, after the panel fitter and pixel multiplier (or
line doubling, if we ever bother with that) have done their job.
Since the fdi link is between the pfit and the pixel multiplier steps
we need to be careful with calculating the fdi link config.

v2: Fix up ilk cpu pll handling.

v3: Introduce an fdi_dotclock variable in ironlake_fdi_compute_config
to make it clearer that we transmit the adjusted_mode without the
pixel multiplier taken into account. The old code multiplied the the
available link bw with the pixel multiplier, which results in the same
fdi configuration, but is much more confusing.

v4: Rebase on top of Imre's is_cpu_edp removal.

v5: Rebase on top of Paulo's haswell watermark fixes, which introduce
a new place which looked at the pixel_clock and so needed conversion.

v6: Split out prep patches as requested by Paulo Zanoni. Also rebase
on top of the fdi dotclock handling fix in the fdi lanes/bw
computation code.
