Add timeout to waiting for vsync so that it can come out
when vsync interrupt is not working.
Need not wait for vsync after timing engine is off.

msm_fb: display: fix iommu page fault when iommu buffer freed

There has possibility that pipe commit come very close to next vsync.
This may cause two consecutive pipe_commits happen within same vsync
period which cause iommu page fault when previous iommu buffer is
freed since mdp stil fetching it. Set ION_IOMMU_UNMAP_DELAYED flag
at ion_map_iommu() to add delay un mapping iommu buffer to fix this problem.
Otherwise four buffer mechanism is needed to avoid this problem..
Also ion_unmap_iommu() may take long time to free an ion buffer. Move
mdp4_overlay_iommu_unmap_freelist(mixer) called after stage_commit()
to increase chance to have pipe_commit (up to stage_commit) is completed
within same vsync period
This patch also fix an potential race condition at wait_for_completion
between show_event thread and wait4vsync thread.

msm: display: Fix composition issues when framework rebooted in suspend.

Currently, if framework is rebooted while in suspend mode, borderfill
is not unset due to which MDP composition can not be enabled. This patch
fixes the issue.

msm_fb: display: add one more pipe_commit delay before free ion buffer

It is possible that two consective pipe_commits happen within
same vsync period.  This will cause iommu page fault due to an ion buffer
that is being fetched by mdp's pipe is freed. It needs one pipe_commit
delay to free ion buffer to prevent iommu page from happening. Therefore
an extra free stage is needed to empty ion buffer free list.
Also, ION_IOMMU_UNMAP_DELAYED flag is not necessary at mapping of an
ion buffer since one pipe_commit delay had been added.

msm_fb: display: fix the suspend/resume hang caused by wait4vsync stuck

wait_for_completion in wait4vsync stucks after multiple suspend/resume
tests. The cause is that when show_event timeout happens, or vsync isr
is disabled for long time, wait_vsync_cnt resets to zero, and in vsync
isr complete_all has no chance to be called which caused mdp hang. So
complete_all needs to be called whenever show_event has timeouts.

msm_fb: display: issue completion when disabling vsync irq

When vsync irq is disabled, vsync_wait_cnt is reset to zero and
completion is issued out as they are done in isr to make sure all
wait_for_completion is released.

mms_fb: display: init pipe default configure as solidfill

Initialize mdp pipes default config as solid fill so that
there will have no memory fetch if pipe are staged into
mixer while flush bits are left behind and set at next vsync.
This is will prevent mdp iommu page fault from happening
at address 0x00000000 during resume.

msm_fb: Fail fb2 open if called during suspend

At present, if msm_fb_open() for fb2 is called during suspend,
we increment the ref_count for fb2 and return success without
turning on the writeback pipeline. This causes the WFD client
think that fb2 is successfully opened whereas fb2_open should
not successful during suspend. Hence, return error if msm_fb_open()
is called for fb2 during suspend.

msm_fb: display: disable mdp blt mode

The switch of blt mode may cause mdp hang on some targets. To avoid
blt switch, we won't allocate the pipe that requires blt
mode. Basically this implies two things: downscaling is done by
rotator and gpu composition is used in case of blt mode is needed.

This implementation is to calculate mdp clk requirement based on the
req data passed from userspace before setting the actural pipe
data. If overlay_set asks for mdp clk that is greater than
mdp_max_clk, meaning blt is needed, overlay_set returns before pipe
allocation or pipe data change, so this way can avoid mdp to work on
wrong pipe data.
