1) While setting BWC check for 90 transform and swap crop
2) Calculate decimation in the getDecimationFactor API itself.
Currently, a residual downscale is calculated and the clients have
to take logs and apply forcible decimation like in MdpCtrl
3) Fix bug where transform gets typecasted to bool

1. Use MDP rotator to rotate RGB layers which are rendered by software
2. Restrict total number of rotator sessions to 4 for all displays
3. Disable RGB layer rotation for all MDP versions < MDP5

Split video with width > 2048 only if source split is absent, and
the relevant system property is set.
In source split the video is split evenly anyway.

Source Split layers always if the driver indicates so by setting
the src_split_always in the capabilities sysfs node.
This is applicable to layers whose width > mixer's width, since
MDP clk rate is dependent on max(mixer_width, layer_width).
This feature can be enabled if the panel height is more than a
certain empirically derived value. Splitting always in those
cases can help with a lower voltage.

Map dirtyRect generated for sourceCrop to layer destination
before using it for calculating ROI for single DSI
panels.

MDP bandwidth limitations can be avoided, if the overlapping region
covered by the smallest layer at a higher z-order, can be composed
on a render buffer using Copybit, and then it can be queued to MDP
along with other layers. It helps to improve performace by avoiding
GPU Composition in use cases like Home Screen pan. To enable this
feature, set system prop "persist.hwc.ptor.enable" to "true" or '1'
and enable Copybit HAL compilation.

Enable BWC for videos with crop and position widths <= mixer width.
Source split was earlier used on split panels only, and BWC was
never enabled (It should at least have been for eligible content).
When source split was enabled for all panels, automatically BWC got
disabled for rotated videos. This change fixes that.

DirtyRect for a layer is generated w.r.t to its buffer
coordinates. It needs to be mapped for layer destination
(display) coordinates before using it to calculate the frame's
ROI.

For panels that cannot accept commands in both the interfaces, we cannot
send two ROI's (for each half). We merge them into single ROI and split
them across lSplit for MDP mixer use. The ROI's will be merged again
finally before updating the panel in the driver.
- Reads panel property of dual control path.
- If dual control path not supported, merge ROI's before
analysing for composition strategies.

Extends partial frame update support for split displays by calculating
changing region(ROI) independently for each half of the screen. In case of
only one half updating, display driver shuts down the DSI/MDP mixer control
of the non updating half.
Maintains two ROI's for each display. In case of Non-split
displays, only left ROI is updated.

When validateAndSet fails we must reset the mDoable flag to false and
close the fb device. This will prevent making a draw call using
invalid resource references and prevent any fd leaks.
Additionally, we should only turn AD on if there are no configuration
errors during prepare call. This will prevent toggling AD between
on/off state in the face of continuous failures.

Since both has same number of pipes with similar

Enable source split for targets with single dsi. This has the
benefit of using 2 pipes for layers whose width (crop) is higher
than line width.

* Mdss driver supports DMA-Multiplexing on wb interface
for certain targets. Add overlay get function to query
this info during pipe allocation for wb.
* UI Scaling on external is not supported on certain
targets due to the lack of availability of pipes with
scalars. Add overlay get function to query this info
to disable action-safe calcs, DRC and others which
require downscaling.

For 8x26, if external display is connected, DMA pipe should never
be occupied by primary display. Otherwise, external display would
lack DMA pipe if switch to GPU composition.

No need to draw dropped layers while doing video only composition
since they are lying outside updating ROI.

Add support for returning pipes based on capabilities.
getPipe() API takes in pipe specifications like format class,
scaling, display, mixer, fb and decides what pipe to return.
The nextPipe() API is now just a private helper.

If using source split to stage 2 pipes on the same mixer stage,
the left pipe needs to be a higher priority than the right.
Add API in overlay to compare pipe priorities and use this in
source split config to stage pipes accordingly.
Add support for 1 pipe config for FB if updating rect is within 2048
pixels.
