- Fix a bug that caused 15% CPU performance drop in Kaveri. This was caused
because we overwritten the initialization of the first pipe (out of eight),
which is dedicated to radeon operation. The fix was tested by Michel Dänzer.
This bug was introduced by a patch I prepared (yeah, my bad) and was merged
to 3.19-rc6. Therefore, I also marked it as Cc:stable.
- Fix sparse warning

drm/tegra: Fixes for v3.20-rc1
This fixes a bit of fallout that was caused by the atomic modesetting
driver conversion and some last-minute changes in the DRM atomic core.
It also fixes a bug exposed by recent changes in the clock framework
which results in non-working HDMI.

drm: tweak getconnector locking
We need to extend the locking to cover connector->state reading for
atomic drivers, but the above commit was a bit too eager and also
included the fill_modes callback. Which on i915 on old platforms using
load detection needs to acquire modeset locks, resulting in a deadlock
on output probing.

get_pipes_num() calls BUG_ON so we can't set it as inline because it produces a
warning as BUG_ON() uses static variables when it is expanded.

This patch fixes a bug in the initialization of the pipelines. The
init_pipelines() function was called with a constant value of 0 in the
first_pipe argument. This is an error because amdkfd doesn't handle pipe 0.
The correct way is to pass the value that get_first_pipe() returns as the
argument for first_pipe.
This bug appeared in 3.19 (first version with amdkfd) and it causes around 15%
drop in CPU performance of Kaveri (A10-7850).

The code in tegra_crtc_prepare() really belongs in tegra_dc_init(), or
at least most of it. This fixes an issue with VBLANK handling because
tegra_crtc_prepare() would overwrite the interrupt mask register that
tegra_crtc_enable_vblank() had written to to enable VBLANK interrupts.

Store a pointer to the CRTC in its atomic state to make it easy for
state handling code to get at the CRTC.

Signed-off-by: Thierry Reding <treding@nvidia.com>
Commit eab3bbeffd ("drm/atomic: Add drm_crtc_state->active") added the
field to track the DPMS state. However, the Tegra driver was in modified
in parallel and subclasses the CRTC atomic state, so needed to duplicate
the code in the atomic helpers. After the addition of the active_changed
field it became out of sync and doesn't reset it when duplicating state.
This causes a full modeset on things like page-flips, which will in turn
cause warnings due to the VBLANK machinery being disabled when it really
should remain on.

Recent changes in the clock framework have caused a behavioural change
in that clocks that have not had their rate set explicitly will now be
reset to their initial rate (or 0) when the clock is released. This is
triggered in the deferred probing path, resulting in the clock running
at a wrong frequency after the successful probe.
This can be easily fixed by setting the rate explicitly rather than by
relying on the implicit rate inherited by the parent.
