* | msm: mdss: enable secure wfd supportAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | Provide APIs to enable secure content display through wifi display. Implement workaround to allocate a secure source pipe so that MDP is allowed to write back to secure buffer.

* | mdss: display: Enable continuous splash for Toshiba 720pSiddhartha Agrawal2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling for MTP, CDP and FLUID devices. The continuous splash flag is set in the platform dtsi which will keep the MDSS and DSI settings intact till the first frame update. Since the MDSS related clocks are enabled in the lk, we still vote for the clocks in our probe to carry them forward. The bandwidth request is made for the same reason as well.

| | | | | | | | | | | | | | | | | | | | fb memory needs to be mapped to a virtual address even before the iommu is attached which happens later.

* | msm: mhl: hdmi: MHL-HDMI handshake implementationManoj Rao2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, HDMI driver adds entries for all the formats that it supports into an internal table. However, when MHL Tx is present, the max format supported should be limited based on the maximum bandwidth supported by the MHL Tx. We implement a handshake between HDMI and MHL drivers to exchange callback function which returns the status of HDMI's TMDS lines that is used by MHL driver before sending RAP messages.

* | msm: mdss: Flush changes to post processing immediatelyCarl Vanderlip2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Current post processing changes wait for a display update to write its data to registers. Trigger post processing configuration at time of update so that the updated features will be updated at next vsync. Needed by destination side post processing features in particular since their updates are made independently of display updates and effect objective display quality.
