* | msm: mdss: Add changes for PP PA v2 functionalityBenet Clark2016-03-23
| | | | | | | | | | | | | | | | | | | | The new version of PA in postproc has added functionality in DSPP and VIG. This change adds functions for handling the reading and writing of these new registers, as well as PA v2 setup in DSPP and VIG setups. This change only adds functionality for global adjustment and memory color adjustment. Change-Id: Iab1644714928055f15cf496185509b1712d0ceae Signed-off-by: Benet Clark <benetc@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | In dual-DSI panel configuration it is possible that panels are physically swapped on the device. In those situations mixer swap is done. There is an old dead code in current implementation which leads to failures in mixer swap use-case. Fix these failures by removing this dead code.

Currently post processing and frame updates have independent flush mechanisms which in certain cases can cause visual artifacts or blank screen. So revert changes to independently flush MDP registers so that post processing piggybacks on flushes for frame updates.
