During cmd rx, only new versions of H/W provide register to read back
the real number of byte returned by panel. For the old versions, reading
this register will not get the right number. In fact, we only need to
assume the returned data is the same size as we expected, because later
we will check the data type to detect error.

The current iteration in get_dsi_id_from_intf() is wrong:
instead of iterating until hw_cfg->intf.count, we need to iterate
until MDP5_INTF_NUM_MAX here.
Let's take the example of msm8x16:
hw_cfg->intf.count = 1
intfs[0] = INTF_Disabled
intfs[1] = INTF_DSI
If we stop iterating once i reaches hw_cfg->intf.count (== 1),
we will miss the test for intfs[1].
Actually, this hw_cfg->intf.count entry is quite confusing and is not
(or *should not be*) used anywhere else; let's remove it.

Currently we're adding CEA modes after the inferred modes, which means
we might get multiple modes that are very close to each other, but
slightly different, which seems a bit silly. That's because duplicate
mode check that occurs when adding inferred modes would not consider
CEA modes as potential duplicates. Reverse the order so that CEA
modes get added before inferred modes, and are thus considered potential
duplicates.

This patch fixes a timing issue that causes a GPU hang when the system
comes out of power saving.
During pm_resume, We are submitting batchbuffers before enabling
Interrupts this is causing us to miss the context switch interrupt,
and in consequence intel_execlists_handle_ctx_events is not triggered.
This patch is based on a patch from Deepak S <deepak.s@intel.com>
from another platform.
The patch fixes an issue introduced by:
commit e7778be1ea
drm/i915: Fix startup failure in LRC mode after recent init changes
The above patch added a call to init_context() to fix an issue introduced
by a previous patch. But, it then opened up a small timing window for the
batches being added by the init_context (basically setting up the context)
to complete before the interrupts have been turned on, thus hanging the
GPU.

Since commit 844b03f277 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

Sometimes (exactly when is a bit unclear) DISPLAY_PHY_CONTROL appears to
get corrupted. The values I've managed to read from it seem to have some
pattern but vary quite a lot. The corruption doesn't seem to just happen
when the register is accessed, but can also happen spontaneosly during
modeset. When this happens during a modeset things go south and the
display doesn't light up.
I've managed to hit the problemn when toggling HDMI on port D on and
off. When things get corrupted the display doesn't light up, but as soon
as I manually write the correct value to the register the display comes
up.
First I was suspicious that we ourselves accidentally overwrite it with
garbage, but didn't catch anything with the reg_rw tracepoint. Also I
sprinkled check all over the modeset path to see exactly when the
corruption happens, and eg. the read back value was fine just before
intel_dp_set_m(), and corrupted immediately after it. I also made my
check function repair the register value whenever it was wrong, and with
this approach the corruption repeated several times during the modeset
operation, always seeming to trigger in the same exact calls to the
check function, while other calls to the function never caught anything.
So far I've not seen this problem occurring when carefully avoiding all
read accesses to DISPLAY_PHY_CONTROL. Not sure if that's just pure luck
or an actual workaround, but we can hope it works. So let's avoid reading
the register and instead track the desired value of the register in dev_priv.
