* | msm: mdss: fix rotator session not being closed correctlyAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | User space expects non-negative number as session id, update rotator mask to avoid making rotator session as negative. When rotator is closed, need to recalculate bus/mdp clock numbers. Change-Id: I6c0e3bfa5394fb64b78fb47be1f24462e320916d Signed-off-by: Adrian Salido-Moreno <adrianm@codeaurora.org>
* | msm: mdss: update performance calculations to include border colorAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | | | Current clock and bus scaling calculations consider only source surface pipes to set clock rate and bus scaling factor, however since MDP also generates pixels for border color this area also needs to be considered for final clock and bus scaling factors for data paths that use layer mixer.

* | msm: mdss: move unstaging of overlay surfaces to display commitAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | | | Perform cleanup of surfaces destroyed with overlay unset until next display update. This enables a smooth transition in case multiple surfaces are unset before next frame update.

* | msm: mdss: remove display commit during overlay playAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | All display commits happen with pan display in order to have a single sync point when using multiple pipes, and avoid blinks that can happen when updating surfaces out of sync. Exception for this case is writeback where commit is still needed, keep this implementation until this exception is corrected from user space applications.

* | msm: mdss: implement commit ioctl for display commitAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | Commit ioctl is used to update contents on display while avoiding console_lock done through framebuffer pan_display path, which causes additional delay on display pipeline leading to flickers on HDMI.

| | | | | | | | | | | | | | | | | | | | play_cnt is used to manage currently displayed buffer, this value is incremental and should be initialized only once for new pipe creation, but overlay set can be called after pipe creation to change params.

* | msm: mdss: use half of panel width when using dual pipeAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | MDP layer mixer only supports up to 2048 width, if the panel resolution is greater than this dual mixer needs to be used. Setup each mixer width as half the panel width instead of allocating max width on left mixer and use left over for right mixer to have better load balancing.
