* A non-updating layer requiring rotation, can make use of
the older rotator buffer written when the layer got first
updated, rather than invoking a new rotator cycle.
* A rotator play is avoided in cases where incoming layer
buffer fd, offset, whf, src-rect, dst-rect, etc are similar
to that of the previous input layer to the rotator.
* For ex: In a usecase where video layer updates happen at
30fps and all other asynchrous UI updates happen at 60fps,
instead of the traditional 60 calls of rotator play per sec,
we now do only 30 thereby saving rotator bandwidth.
* Property "debug.rotcache.disable" can be used to disable
this feature.

Add support for rotator downscale. This is enabled from 8994 onwards
Constraints:
--Downscale should be a power of 2, max upto 32
--Both directions should have equal downscale
--{src_w, src_h} mod downscale = 0
--No BWC
--No Interlaced video support
The rotator's destination rect is modified to reflect the presence of
downscale. Any downscale calcs should be done only after adjusting
crop to meet rotator's requirements.
Smaller downscale is used if we need to chop off any more than 1
line or pixel.

Currently for Mdss rotator we manipulate the layer buffer dimensions
to be equal to what rotator's destination dimensions would be, so that
these could be fed to MDP. Instead, this patch introduces APIs in
rotator so that hwc can directly query destination crop, width, height,
format from rotator.
This also simplifies the updateSource() and configRotator() helpers.

BWC buffer size was added to address worst case sizes. But it doesn't
take care of RGB formats. Also the YUV CbCr worst case is 32x2 not
64x2. This change fixes those.

When ION was not ref counted, we needed to maintain the previous
session memory until the new one was taken by MDP. ION being
ref counted now, it is not necessary to maintain previous memory
allocation.

On systems that do not have a Contiguous Memory Allocator (CMA) it is
the responsibily of the client to specify the required address alignment.
Additionally, we centralize size alignment to so that overlay clients
do not need to take of this.

Compressed output buffer size calculation for MDSS Rotator needs to
be performed according to destination rectangle (rotated src rect)
due to alignment requirements (like non-BWC calculation).
Change-Id: I6a232d77ca5fce42a1cc3e7f406c9cc4d46553ed
For BWC, update the rotator buffer size calculation in display HAL
as MDSS driver needs to allocate for both chroma (U & V) planes.

- This adds support for Bandwidth Compression.
- If MDSS supports BWC, then we set BWC flags
to both Rotator(encode) and overlay(decode)
Change-Id: I6f7800716a2ce2ab855f4c0b1a53cd96f7d06d74
Since MDSS rotator will crop, the crop rectangle for overlay
will always start from (0,0).

In extreme cases, when all pipes are used, the buffer is insufficient.
Reduce logging by striping off unnecessary bytes.
Change-Id: I5a6ffb9ff288e389eea4e9ca4ac850ed59d539ff
Older mdp rotator does 90 first and flip next,
forcing HAL to swap flips, in presence of 90.
Newer mdp does flip first and 90 next, owing to DMA pipe.
(Also similar to GPU flip handling). So we can pass flips as-is.

We cleared the values after MSMFB_OVERLAY_SET, which could cause dumpsys
to not show them.
Clear the values in setTransfrom, before applying incoming values.

-Add support for Video via overlay on 4k2k external panel.
-Add support for rotating videos on 4k2k panels. We use
pre-rotation in hwc to rotate a video into a single buffer,
irrespective of panel size. Then this buffer is fed to MDP.
Rotator objects are managed by the new RotMgr.
-Cleaup mdpcomp and overlay.

Fix rotator output buffer size for mdp and mdss rotators.
Output size is based on rotated width & height.
Output format can be different than source format.
It could be same if using mdss rot or using fastyuv mode in mdp rot.
Deprecate the static mapping of rotator input and output formats.
Driver will be responsible for correctly populating the dest format that its
wishes to use.

1. Due to alignment requirements on HAL_PIXEL_FORMAT_YV12 format,
rotator buffer size calculation needs to be performed based on
rotated width and height because buffer size can be different when
width & height are swapped due to 90 degree rotation.
2. Input and output color formats are same for MDSS Rotator.

* Set mdp source format as rotator output format
rather than determine it from a fixed mapping of
input/output formats.
* This is needed since for the same input format
to rotator, fastyuv mode if enabled may result in
a different output format than the one if the mode
is not enabled.
* Do the inline optimization for rotator where possible

Engage the rotator to assist MDP in performing video downscale for
primary and external. This saves bandwidth and avoids causing the
driver to make too many panel mode switches between BLT (writeback)
and non-BLT (direct) modes.

- Secured contents shared with hardware should be uncached.
- Secure heap needs to be contiguously allocated & aligned to 1MB,
which is not supported by IOMMU heap.

Due to alignment requirements on venus format, rotator buffer size
calculation needs to be performed according to destination buffer
dimensions. Due to these alignments, the buffer can be different
when width and height are swapped due to 90 degree rotation.

Venus color format is not supported on older platforms. Add target

older platforms.

Remove state based pipe handling and make pipes tracked dynamically.
Add the configStart, configDone, nextPipe availablePipes APIs.
Remove setState API.
-configStart marks all pipes available.
-configDone garbage-collects unused pipe objects.
-nextPipe returns the index of next available pipe and create a corresponding
pipe object if not present
-availablePipes returns total of "unallocated" pipes. (Pipes could be allocated
but unused)
Changes in hwc adapt to the new overlay APIs.
Compile out MDP comp.
Remove unused files in overlay and hwc.
Update licenses.
