2014-05-20drm/i915/chv: Use RMW to toggle swing calc initVille Syrjälä
The spec only tells us to set individual bits here and there. So we use RMW for most things. Do the same for the swing calc init. Eventually we should optimize things to just blast the final value in with group access whenever possible. But to do that someone needs to take a good look at what's the reset value for each registers, and possibly if the BIOS manages to frob with some of them. For now use RMW access always.

2014-05-16drm/i915: Track has_audio in the pipe configDaniel Vetter
Including state readout and cross-checking. This allows us to get rid of crtc->eld_vld on hsw+. It also means that fastboot will be unhappy if the BIOS hasn't set up the audio routing like we want it too. Wrt fastboot and external screens I see a few options: - Don't. - Try to fix up eld, infoframes and audio settings after the fact. But that means some pretty extensive reworking of our code which currently does all this while the pipe/port is still off. I won't bother with converting SDVO over to this because the audio support for SDVO is very lacking: - We don't update the eld. - We don't update the audio state on the sdvo encoder. - We don't check whether the platform can even feed audio to the sdvo encoder. I've converted hdmi, dp & ddi all in one go since ddi needs both hdmi and dp converted and so doing it step-by-step would have required a few intermediate hacks.

2014-04-22drm/i915: Allow user modes to exceed DVI 165MHz limitVille Syrjälä
In commit commit 6375b768a9850b6154478993e5fb566fa4614a9c 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.

2014-03-10drm/i915: Allow HDMI+HDMI cloning on g4xVille Syrjälä
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.

When cloning HDMI with other output types, we can't use 12bpc since the clocks for the other encoder types would be off. So have intel_hdmi_compute_config() check if there are other encoders besides HDMI being fed from the same pipe, and if so, pick 8bpc insted if 12bpc.

2014-03-10drm/i915: Make encoder cloning more flexibleVille Syrjälä
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.

2014-02-14drm/i915: add unregister callback to connectorImre Deak
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.
