* drm/radeon: rework panel mode setupAlex Deucher2012-08-29
| | | | | | | | | | | Adjust the panel mode setup to match the behavior of the vbios. Rather than checking for specific bridge chip ids, just check the eDP configuration register. This saves extra aux transactions and works across DP bridge chips without requiring additional per chip id checking. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/radeon: fix non revealent error messageJerome Glisse2012-07-25
| | | | | | | | | | | | | | | We want to print link status query failed only if it's an unexepected fail. If we query to see if we need link training it might be because there is nothing connected and thus link status query have the right to fail in that case. To avoid printing failure when it's expected, move the failure message to proper place.

* drm/radeon/kms: don't try to be smart in the hpd handlerAlex Deucher2011-08-15
| | | | | | | | | | | | | | | | | | | | | Attempting to try and turn off disconnected display hw in the hotput handler lead to more problems than it helped. For now just register an event and only attempt the do something interesting with DP. Other connectors are just too problematic: - Some systems have an HPD pin assigned to LVDS, but it's rarely if ever connected properly and we don't really care about hpd events on LVDS anyway since it's always connected. - The HPD pin is wired up correctly for eDP, but we don't really have to do anything since the events since it's always connected. - Some HPD pins fire more than once when you connect/disconnect - etc. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=39882 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had on our list, to pick a correct digital encoder block.

V2: fix silly addition of connector dig_block and cleanup the other places in the code that pick the encoder.
