When Dynamic Resolution Change (DRC) is triggered in the WiFi display
stack, it results in a PAUSE and a RESUME event. During DRC, the
dimensions of the framebuffer are changed. To support DRC we need to:
1. Check if a RESUME event is the result of a valid DRC event
2. Reconfigure the display's attributes to reflect resolution change
3. Enable MDP downscaling when necessary (Valid DRC cases)

* For HDMI and non-Hybrid WFD solution, on receiving
online event, display hal sends hotplug connect to SF.
* In case of such displays, set them as active only
after receiving an unblank call.
* For Hybrid WFD solution, since display hal will not
be receiving unblank call from SF, set it as active
as part of processing online event itself.

A display could be split if its dimensions exceed 2048 or in case
of primary if we make it so via device tree property.
Add an API to find if a display is split. Use this API instead of
going through a set of conditions in various use cases.
Rename the HighRes, LowRes objects to a more appropriate Split and
NonSplit respectively

1. During PAUSE event, trigger an invalidate frame
which will unset the pipes (in draw call) and invoke
display commit as part of hwc_event thread.
This is required to avoid iommu page faults arising when
WFD encoder is in the middle of configuring buffers
and providing to Writeback as part of RESUME event and
Display HAL tries to invoke display commit as part of PAUSE.
2. Allow usage of rotator for Primary when WFD is in Pause
state.
The above changes are required to support secure/non-secure
video playback on HDCP WFD session and Pause/Resume.

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().

For external we assume even split. If driver doesn't specify any split

With this change we are moving MDP composition from all-or-nothing
implementation to mixed mode implementation where layers can
partially be composited through MDP and while rest of the layers are
composed / cached in framebuffer.
- Mixed mode design is based on layer caching
- Mixed mode path is configured only when non-bypassing
layers are cached.
- Never allow mixed mode when FB needs to be udpated.
- If we cannot bypass all MDP comp marked layers, bail
out completely.

During Pause event, set external pending state, there by

This change introduces hdmi pending state, where we allow
frames to fall back to FB, closing all MDP pipes.
Pipes could be used by primary (mixer 0) in which case moving
them to external (mixer 1) involves unsetting them and setting
them in the same round which is not recommended by the driver.
It will fall back to GPU till HDMI is configured on a connect
event.

On HDMI connection, two uevents are generated
1."change@/devices/virtual/switch/hdmi"
2."change@/devices/virtual/switch/hdmi_audio"
Since we look for "change@/devices/virtual/switch/hdmi",
Display HAL will process the hotplug request twice.
This causes regression on HDCP enabled devices.
Change involves to check for uevent str with
"change@/devices/virtual/switch/hdmi" to ensures
that we process connection request only once.

This commit has the following changes:
1. Use hdmi switch node for hdmi hotplug
- uses /devices/virtual/switch/hdmi switch_state to determine
the hdmi connect/disconnect
- this switch will be set to 1 on connect and 0 on disconnect
- on connect, open framebuffer device, will trigger the hdcp
authentication.
- the driver will set the hdmi_audio switch to indicate that
the HDMI sink supports audio
2. Enable HDP on unblank
- this will resolve the device freeze during the bootup with hdmi
connected

(cherry picked from commit 953b04b3cbba2f91d25795e5b0560c13d47844b0)
Cleanup overlay for external from the draw thread. If done from the uevent
thread, its possible that the object being used by draw thread is deleted by
uevent thread.
This also removes unnecessary side-effects where libexternal sets states in
hwc, whereas, it could be set from hwc itself. There should be no need for
libexternal to modify states in hwc.

We are seeing errors where a device's hwcVsyncThread is not present for some
reason. The surface flinger has not crashed, so either the thread never got
created, or it exited withouth throwing an error. This patch adds some more
verbose on-error logging to the HWC as an attempt to verify the theory that the
thread does not get created, or fails in pthread_create. While we're at it, we
add the same logging at pthread_create() for hwcUeventThread, as well.
Also, replace the lseek()+read() with a pread() combo in the vsync thread.

* Read sysfs entries to get vsync timestamp from kernel.
* External display continues to use uevents for hotplug events
* A new thread, vsyncThread is created to read and send vsync
timestamps to HAL.
* Disable H/W VSYNC for MDP 5.x targets until kernel changes are
complete.
* Synchronization is needed to make sure read() is not called
by hwcVsyncThread when VSYNC is disabled.
