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

1. Add hook to dump the layers going to VDS based virtual display.
2. Furthermore, add utility function to dump the frame buffer and
WB output buffer. This will be enabled via a system property
debug.hwc.enable_vds_dump
Once dumping is enabled, the dumps can be extracted from
/data/vds.fb.FORMAT.XRESxYRES.raw
/data/vds.wb.FORMAT.XRESxYRES.raw

FLIP flags need to be considered while calculating srcCrop and
displayFrame even when a layer is updated partially on dual 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.

In display list if one layer has same parameters
as framebuffer on index '0'. Use this layer
as FB and blit other layer(s) on top of it.

If the display list contains single layer and that layer
has same properties as Frame Buffer, avoid BLIT on Frame buffer
and pass it directly to display.

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.

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.

Pass the acquire fence count to driver on a buffer sync ioctl call
for the rotator. The count is always 1 since the ioctl is called
once per rotator session. This also means that the rotator has to
wait for only 1 layer always.
The earlier assumption that in the presence of a session id, the
acquire count would be NOP, does not seem to hold with the driver.

* 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.

Set it to LINE_MODE if the number of active rotator
sessions are 0.
Set it to BLOCK_MODE if

** (or) mBufferMirrorMode is set

* Provide a binder interface call for wfd module
to inform display about the start/stop/pause/resume
of wfd session.
* This is needed for wfd-hdmi synchronization in
case of v4l2 wfd solution. If hdmi is plugged
in during v4l2 wfd session, display-hal waits in
uevent thread for wfd teardown notification from
wfd module, before going ahead with configuring
external display.
* For VDS WFD solution, display-hal waits in uevent
thread for wfd-teardown to be signalled from
the composition thread.

The display view frame needs to be set before calling trimLayer api
because it uses view frame to find the scissor for display, which is
used to clip crop for out-of-bounds display frame sent by framework.
If mViewFrame is not set, scissor will be empty rect, which leads to
wrong source crop calculation.
