for tile format make the rotator source buffers aligned to 64 X 32.
This avoids rotator hang during source fetch.

- In Buffer mirror mode, the output on the external should be rotated
based on the primary orientation.
- this is used for the side sync feature.
- buffermirrormode has higher precedence over external orientation
- Add binder interface to enable/disable buffermirror mode

On WFD/HDMI connection, if the configured resolution is less than
Primary Resolution, Display HAL does the following:
1. sends hpd notification to SF with primary resolution.
2. configures MDP pipes with configured Resolution.
This is done to improve UI quality as MDP has better downscale
filter options compared to GPU.
This works only for QCOM WFD proprietary solution.

- Make aspectratio calculations independent of ext dpy w/h
- pass hwc_rect_t to getAspectRatioPosition function instead of
x, y, w, h
- overload getAspectRatioPosition func to return the upscaled

Add assertive display support to hwc. This feature takes effect when
node /sys/class/graphics/fb*/ad is present. This signifies that that LM0
is being used with fb* for writeback.
When a video playback begins we write "1" to this node to indicate to
post processing that a writeback will happen. Likewise a "0" is written
to this node when playback stops.
The original contents are worked upon and the modified output is fed
via writeback to either rotator or mdp as appropriate.
The feature doesnt trigger when either:
1) Buffer size exceeds 2048
2) External display is connected
3) Multiple yuv streams are present
When this mode is active, MDP comp is applied only to yuv layer.

If the left split is not published by the driver then the default should
be even split. This was missing from the configuration in utils. This is
already taken care of in framebuffer configuration and mdp composition.

1. Since SF doesnt invoke blank for virtual display,
handle pipe clean up as part of Primary display
blank.
2. Support virtual display to query display attributes.
This refactor is done to address Framework reboot issue.

Increase precision from float to double in triming calcs.
This improves the output. We need this since ultimately
we assign to int which would truncate excesses. With float
due to lower precision, we end up slightly lower than an
integral value.

Implement sync for rotator.
If a buffer is rotated, it can be used by producer soon after
rotation (and it wont have to wait until vsync).
Mdp waits for the rotator buffer's release fence to signal
to start display.
Hwc waits for previous access to rotator buffer by MDP to finish
before using it

Crop swapping is being done on V flip, rather it should be done

Add support for unevenly split primary displays.
The driver provides info about the split via msm_fb_split sysfs node
For external we assume even split. If driver doesn't specify any split
for primary, we default to even split.

When WFD is connected to 8x26
1) On Video transition, have 1 padding round if external connected.
Required to shift pipes across mixers.
2) Request DMA pipe always for FB on WFD.
Necessary for rotation + writeback
3) Disable non-worm-hole calcs on external (because of 2)
4) Disable action-safe calcs on external (because of 2)

These conditions are statically determined. BWC might get used and
still fail (or cause failure of subsequent pipe requests) if SMP
