drm/amd/display: Add one to EDID's audio channel count when passing to DC

2018-03-21T05:24:47+00:00

DC takes channel count to mean the actual count. cea_sad's channels
represent it as number of channels - 1.

drm/amd/display: We shouldn't set format_default on plane as atomic driver

2018-03-21T05:23:51+00:00

This is still a leftover from early atomic brinup days.

drm/amd/display: Fix memleaks when atomic check fails.

2018-03-07T21:28:22+00:00

While checking plane states for updates during atomic check, we create
dc_plane_states in preparation. These dc states should be freed if
something errors.

Although the input transfer function is also freed by
dc_plane_state_release(), we should free it (on error) under the same
scope as where it is created.

drm/amd/display: Set irq state only on existing crtcs

2018-03-07T21:27:43+00:00

Because AMDGPU_CRTC_IRQ_VLINE1 = 6, it expected 6 more crtcs to be
programed with disabled irq state in amdgpu_irq_disable_all. That caused errors and accessed
the wrong memory location.

drm/amd/display: Fixed non-native modes not lighting up

2018-03-07T21:27:36+00:00

There is no need to call drm_mode_set_crtcinfo() again once
crtc timing is decided. Otherwise non-native/unsupported timing
might get overwritten.

drm/amd/display: Call update_stream_signal directly from amdgpu_dm

2018-03-07T21:27:34+00:00

There's no good place in DC to cover all place where stream signal should
be updated. update_stream_signal depends on timing which comes from DM.

drm/amd/display: Make create_stream_for_sink more consistent

2018-03-07T21:27:30+00:00

We've got a helper function to call dc_create_stream_for_sink and one
other place that calls it directly. Make sure we call the helper
functions always since we need to update a bunch of things in stream and
don't want to miss that.
