This allows the LPE HDMI driver to clean up its global variable
reference.
Also drop to pass the eld pointer because the connection status and

The LPE audio configuration depends on the pipe, thus we need to pass
the currently used pipe. It's now embedded in struct
intel_hdmi_lpe_audio_eld as well as port id.

The pipe gets cleared to -1 for non-MST before the ELD audio
notification due to the MST audio support. This makes sense for
HD-audio that received the MST handling, but it's useless for LPE
audio. Handle the MST pipe hack conditionally only for HD-audio.

Enable unmute/mute amp notification. This doesn't seem to affect
HDMI support so this is done unconditionally.
An earlier version of this patch set a chicken bit at address 0x62F38
prior to the mute/unmute but this register doesn't seem to do anything
so this phase was removed.

The conversion of stolen to use phys_addr_t (from essentially u32)
sparked an interesting discussion. We treat stolen memory as only
accessible from the GPU (the DMA device) - an attempt to use it from the
CPU will generate a MCE on gen6 onwards, although it is in theory a
physical address that can be dereferenced from the CPU as demonstrated
by earlier generations. As such, using phys_addr_t has the wrong
connotations and as we pass the address into the DMA device via
dma_addr_t (through the scatterlists used to program the GTT entries),
we should treat it as dma_addr_t throughout.

This somehow fixes an issue where sync-to-vblank longer works correctly
after resume from suspend.
From a HW perspective, we don't need the IRQs turned on to be able to
detect flip completion, so it's assumed that this is required for the
voodoo in the core DRM vblank core.

The size computations done in the ioctl function use an integer.
If userspace submits a request with req->cmd_nr or req->cmd_buf_nr
set to INT_MAX, the integer computations overflow later, leading
to potential (kernel) memory corruption.
Prevent this issue by enforcing a limit on the number of submitted
commands, so that we have enough headroom later for the size
computations.
Note that this change has no impact on the currently available
users in userspace, like e.g. libdrm/exynos.
While at it, also make a comment about the size computation more
detailed.

We were trying to print an error message if we timed out here, but the
loop actually ends with "tries" set to UINT_MAX and not zero. Fix this
by changing from tries-- to --tries.
A for loop would actually be the most natural way to do this. My fix
means we only loop 99 times instead of 100 but that's probably ok.

This patch replaces specific atomic commit function
with atomic helper commit one.
For this, it removes existing atomic commit function
and relevant code specific to Exynos DRM and makes
atomic helper commit to be used instead.
Below are changes for the use of atomic helper commit:
- add atomic_commit_tail callback specific to Exynos DRM
. default implemention of atomic helper doesn't mesh well
with runtime PM so the device driver which supports runtime
PM should call drm_atomic_helper_commit_modeset_enables function
prior to drm_atomic_helper_commit_planes function call.
atomic_commit_tail callback implements this call ordering.
- allow plane commit only in case that CRTC device is enabled.
. for this, it calls atomic_helper_commit_planes function
with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.
