* | msm: display: Add pipe type selection in overlay requestVinu Deokaran2016-03-23

* | msm: mdss: modify MDSS idle power collapse exit sequenceAravind Venkateswaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | When MDSS is idle power-collapsed, any events that require hardware programming should result in exiting idle power collapse. Currently, this is only done whenever a screen udpate happens. However, it is possible that other APIs may be called prior to the actual screen update. To address these cases, add the exit sequence call at the interface level as well. Change-Id: I162e1c1c4137a2ba20ed0b76f0c182c2c931cc87 Signed-off-by: Aravind Venkateswaran <aravindh@codeaurora.org>
* | msm: mdss: move ULPS configuration to DSI clock controlAravind Venkateswaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | DSI Ultra Low Power State (ULPS) mode is property of the DSI data and clock lanes. Current implementation requires the MDP command interface to send explicit events to the DSI controller to config ULPS mode. However, it would be a lot more efficient if the DSI controller would independently decide to enter/exit ULPS based on whether the link clocks are enabled or not. This also ensures that if any DCS commands need to be sent when ULPS is enabled, the DSI controllers will exit ULPS accordingly.

* | msm: mdss: add support for RT/NRT trafficRadhika Ranjan Soni2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | RT/NRT feature splits the AXI traffic over two AXI ports. By diverting RT/NRT traffic to individual AXI ports, NRT traffic can be throttled by NOC at SoC level based on AXI port#. Having this capability can help tweak QoS based on use-cases. This change adds support to identify real time and non-real time clients and acocrdingly program HW to take care of routing the RT/NRT traffic to respective AXI ports.

* | msm: mdss: Add support for dynamic mode switchSandeep Panda2016-03-23

If the panel is configured in video mode, it would be power efficient to be able to dynamically switch to command mode on need basis. This change adds the support by providing an IOCTL to switch between video mode and command mode at runtime.

* | msm: mdss: fix OT limit configuration for WB1 moduleUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Each VBIF client can be configured for its number of outstanding (OT) transactions. Currently we can have as high as 13 of these VBIF clients within MDP. OT configuration for these clients is spread across multiple registers. Current implementation of rotator OT limit is not considering these multiple registers which leads to incorrect OT limit configuration for WB1 WR VBIF client. Fix this by adding logic to select correct register offset. Change-Id: I7b4f7ac37ff5c8a85f35dbeb6a6c450b157c4b3a Signed-off-by: Ujwal Patel <ujwalp@codeaurora.org>

* | msm: mdss: fix handling of runtime pm ref counts for fb deviceAravind Venkateswaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current implementation, pm runtime status for the framebuffer device changes to active when the overlay session is started. With idle power collapse feature enabled, it is possible that the MDSS core could be turned off prior to starting the overlay session depending on the duration of the idle timeout. This may result in an invalid hardware configuration leading to various target instabilities. Fix this by holding a reference to the pm runtime when mdp overlay is turned on. Similarly, when the userspace process is killed, wake up MDSS from idle power collapse before shutting down the fb device.

| | | | | | | | | | | | | | | | | | When ppp hw is performing csc from yuv to rgb there is a color swap. In order to account for this we need to swap the unpack and packing order. Change-Id: I55df9a87300f3ce2c9bf5352725f3ce1d2b1b8a4 Signed-off-by: Terence Hampson <thampson@codeaurora.org>
* | msm: mdss: send panic/roburst signal to bimc based on fill levelDhaval Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | MDP hardware will send panic/roburst signal to bimc based on fill level for all pipes connected to realtime interferfaces. This allows bimc to priortize the MDP traffic across all bimc ports, regardless of other clients' priority. This feature is not for non-realtime clients like writeback.
