9fe041f6fd drm/msm: Add msm_gem_get_and_pin_iova()
Add a new function to get and pin the iova memory in one
step (basically renaming the old msm_gem_get_iova function)
and switch msm_gem_get_iova() to only allocate an iova but
not map it in the IOMMU. This is only currently used by
msm_ioctl_gem_info() since all other users of of the iova
expect that the memory be immediately available.

9a5e3fce4b drm/msm/dpu: Replace dpu_crtc_reset by atomic helper
Since we removed all suspend logic from the crtc code (see patch 3/4),
dpu_crtc_reset does the same things as drm_atomic_helper_crtc_reset, so let's
just replace it with a call to the atomic helper.

7a007a121d drm/msm/dpu: Remove suspend state tracking from crtc
Since drm core's modeset locks serialize atomic commits, we don't need to
track whether or not we're in a suspended state from inside the crtc for
dpu_crtc_enable/disable. This patch removes the suspend logic from the crtc and
removes the relevant tracing from dpu_trace. Since we removed all calls
to dpu_kms_is_suspend_state, we can remove that function and the
suspend_state field of dpu_kms as well.

82e223a5d8 drm/msm: dpu: Fix memory leak caused by dropped reference
We are currently leaking a drm_crtc_commit struct for every atomic
commit containing plane state. The dpu plane destroy function cleans up
the fb reference manually, but fails to release the commit ref. As a
result, we just keep allocating drm_crtc_commits without ever freeing
them. Fortunately there's a helper function which will clean up all of
our mess at once, so use that.

Thanks to Doug Anderson for reporting the memory leak (and leaving
breadcrumbs from kmemleak!).

the need for a return value. This function is also never used
outside of dpu_plane.c, so the function is made static.

v3: Using helper function _dpu_plane_get_kms() instead of doing
it locally.

9a9ede3f71 drm/msm/dpu: Remove _dpu_crtc_power_enable
All checks for _dpu_crtc_power_enable are not true, so the function
can never return an error code. This removes the need for the
function as pm_runtime functions can be used instead.

v3: Separated _dpu_crtc_power_enable into _dpu_crtc_power_enable and
_dpu_crtc_power_disable for clarity.

v4: Removed both _dpu_crtc_power_enable and _dpu_crtc_power_disable
and called pm_runtime_get_sync and pm_runtime_put_sync from all
call points

2a7a92fc31 drm/msm: dpu: Consolidate atomic_check functions()
dpu_plane_atomic_check() is a very thin wrapper around
dpu_plane_sspp_atomic_check(). All it does is a NULL-check of state->fb,
which is already done by drm_atomic_helper_check_plane_state(). Further,
the helper sets state->visible = false when this is true. So remove
dpu_plane_atomic_check() and just use dpu_plane_sspp_atomic_check()
directly.
