The list of used files was generated using an annotated make log and was then compared with new files added since the public release of kernel version 3.10.00. New files which were added but not used have been removed from the tree. A diff was also run to determine the list of files that had been modified since the release of kernel version 3.10.00. These files were then scrubbed based on the current kernel configuration, removing invalid and unused conditionals. Some files which support planned functionality or are useful in debugging have been excluded from this reap.

* | msm: mdss: release all overlay resources on last fb releaseUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | There are cases where the last frame buffer reference is released from a different pid than the one who originally allocated the resource. In these cases we can still deallocate all resources currently allocated as we know that all references on fb dev have been released. This issue was previously fixed by a42150bd. But later it again resurfaced with 831a828. Change-Id: Ie35194b1e11ae90ff886b1be22cf02c842a76d1a Signed-off-by: Ujwal Patel <ujwalp@codeaurora.org>

| | | | | | | | | | | | | | | | | | When BWC is enabled, rotator format needs to be swapped from RGBA to BGRA to avoid color mismatch on the ouput image.

| | | | | | | | | | | | | | | | | | | | | | | | | | For command mode dual DSI panels, currently the interface blank and panel OFF events are called twice, once for each interface control off function. The panel and both the DSI controllers get turned off during the first interface BLANK and PANEL_OFF events itself since each interface handler internally gets called for both the DSI controllers. Hence, call the interface events only once for the left mixer controller off function.
