b39f8151ab hwc: Fix locking.
Remove the unnecessary blank lock, mdp comp lock, secure lock.
Rename the ext lock to a more appropriate draw lock.

The mdp comp lock is at an incorrect place and causes unwanted
objects to show up in dumpsys, since configDone hasnt cleaned
them up yet.

dump(), blank(), draw() should all acquire a common lock.
draw() includes prepare() and set().

f40f2c88d5 hwc: Disable idle invalidation for command mode panels
Command mode panels have an internal framebuffer with which they
refresh, hence the idle invalidator isn't needed for them.

Saurabh Shah
a9da08f5af hwc: Add assertive display support.
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.

af5f5971d4 hwc/overlay: Prevent pipes from switching mixers

subsequent rounds. This change prevents that and makes sure there
is one composition round where a pipe being transferred to another
mixer of the same display is UNSET

2a4eb1b965 hwc: Configure framebuffer before other layers.
If framebuffer needs to be configured, configure it before all the
other layers in mdp composition. This helps in cases where we are
out of SMPs and framebuffer configuration fails owing to that.
Framebuffer being the fallback path, should always get highest
priority when reserving SMP blocks

d974324e4a hwc: Add setting to disable idleinvalidator
Added the ability to disable idleInvalidator when the
debug.mdpcomp.idletime property is set to "-1". The hwc test app
displays image on the screen with surface flinger turned off.
This causes timeout, so this change is to allow the testapp to
disable the timeout functionality by setting property.

If an incoming layer has HFLIP tranform it needs two lines of

1k this is costly. Fallback to GPU if RGB layer transform has HFLIP.

0ceeb6ad01 hwc/overlay: Introduce padding round between DMA modes.
Introduce a padding round between the DMA line and block modes.
Do this based on whether DMA is actually being used, when block mode

This relieves the driver of doing an UNSET ahead of vsync which could
cause blinks in all such transition scenarios.

This approach should lead to smooth transitions for multiple targets
with the exception of secure videos, where there could be a blink in
any of the different approaches we use.
