* | msm: mdss: Fix dither matrix configurationDhaval Patel2016-03-23
| | | | | | | | | | | | | | Configure entry 0 to entry 15 in dither matrix. Change-Id: I1259c121e84078325e54d952cbd2671031df2978 Signed-off-by: Dhaval Patel <pdhaval@codeaurora.org>
* | msm: mdss: Check DSI controller status periodicallyDhaval Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Send Bus-Turn-Around (BTA) command to check DSI controller status periodically and check the response from controller. Update appropriate response in frame buffer status node if controller is not responding. Sending BTA command is useful for the video/command mode panels when it stops responding during ESD stability tests.

| | | | | | | | | | | | | | | | | | | | | | Add Bus-Turn-Around (BTA) status check API in DSI controller to check if it is alive or not. Subscriber of this API should send relevant notification to user space for correct action. Update fb driver and cmd interface to support the BTA failure scenario.

* | msm: mdss: Program phase factors for QSEED in Dual display modeSree Sesha Aravind Vadrevu2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | When scaling is involved during video playback for dual display high resolution panels, the scaling factors such as phase step and initial phase need to be programmed to avoid mismatched textures and hardware hangs. Also, software pixel extension needs to be enabled. The data is received from user module through OVERLAY_SET. This feature is only enabled for YUV formats in VIG pipes.

* | msm: mdss: Fix CSC programming for VIG3 pipeUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | CSC programming assumes that pipe numbers are symmetric for same type. This assumption is not valid with APQ8084 and leads to skipping of CSC programming for VIG3 pipe. Fix this by using helper APIs to find out if pipe is VIG or not rather than directly manipulating data structures.

| | | | | | | | | | | | | | | | | | | | | | | | Shutdown the power for DDC (Display Data Channel) module only after HDCP (High-bandwidth Digital content Protection) module has been turned off as HDCP continue to use DDC line until it is turned off. Also, no need to check for DDC hardware status on HDCP off as once the cable is disconnected it will not be updated.

* | msm: mdss: Enable dynamic clock gating for MDSS AHB clockShalabh Jain2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | On APQ8084, currently AHB clock is always on from device tree settings. With this change, it will be enabled if BWC decode is enabled and source dimensions are changed. Since the source dimensions are double buffered, the MDP AHB clock will have to be forced on before writing to the source dimension registers and then the force on turned off after the changes have been applied (i.e. next vsync).

One system shutdown/restart thread which calls shutdown routine registered through device driver. Other closing of frame buffer devices from user processes. Fix race condition between these two contexts by using proper locking mechanism and releasing all the resources.

Nor should it be limited for all backlight drivers (should be implemented in the culprit panel's set_backlight func). This reverts commit 2e5776fdb8acd50ad84752df0c6e0debf42cdf5d Change-Id: Idcbf26eb3babb2a29964b9c7fb8e95aa31a8c5b8 Signed-off-by: Carl Vanderlip <carlv@codeaurora.org>
