* | msm: mdss: update the programmable line value during VRRPadmanabhan Komanduru2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Update the programmable fetch start line register during variable refresh rate (VRR) operations. This is needed since the vertical front porch value changes when there is a change in fps. Also, do not perform fetch start configuration during boot up when continuous splash screen is enabled. The feature will be enabled in LK. This is needed for proper VRR operations until first suspend resume.

| | | | | | | | | | | | | | | | | | | | | | | | | | With MDSS idle power collapse feature enabled, it is possible that the runtime suspend callback for MDP device to be called when there are no display updates. This results in MDSS GDSC to be turned off in idle screen usecases, and would subsequently be turned back on upon the next update. However, toggling GDSC can be an expensive operation and should only be done when it is expected to be off for a substantial time. To achieve this, enable the runtime autosuspend status for the mdp device. Change-Id: I6e4127efe7b01d7e164b0763d34995c82c2e8be9 Signed-off-by: Aravind Venkateswaran <aravindh@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With MDP idle power collapse feature enabled, MDSS GDSC gets turned off whenever there are no updates sent to the panel which results in all hardware registers getting reset. These hardware registers need to be restored whenever on the next udpate. Currently, this restore functionality is only supported for command mode panels. However it is possible that there could be additional framebuffer devices that may be active (such as a writeback device) in conjunction with the primary panel. In such cases, if idle power collapse happens, then these control paths may not get correctly restored leading to unexpected behaviors. Fix this by preventing MDP idle power-collapse when such panels are active. Change-Id: I226e72086bb6232ae452a999d961c80f2841f833 Signed-off-by: Aravind Venkateswaran <aravindh@codeaurora.org>

* | msm: mdss: fix DSI clock handling for split display configurationAravind Venkateswaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In split display mode, the clocks for both the DSI controllers are sourced out of a single PLL (typically the left controller). In the current implementation, the clocks are independently controlled whenever the broadcast mode is not enabled. However, it is possible that if the clocks for right controller alone are turned on, the left controller's phy could already be clamped, leading to that PLL not getting locked. Fix this issue by ensuring that the clocks for the master controller (left controller) are always turned on whenever the clocks for the right controller (or the slave controller) are turned on.

* | msm: mdss: restore mdss register when clocks are turned onAnurag Singh2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When MDSS idle power collapse feature is enabled, MDSS GDSC can be turned off for idle screen usecases. As a result, whenever MDSS GDSC is turned back on, all MDSS registers need to be restored. Current implementation restores this as part of bus bandwidth control API which is only called whenever interface clocks are turned on. However, the correct approach is to restore the hardware state whenever any new register programming needs to be done. Therefore, move the call to restore MDSS state from the bus bandwidth control function over to the MDSS clock control function.

* | msm: mdss: Ensure pipe are unstaged before destroyJayant Shekhar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | There are corner cases when pipes are still staged after recovery sequence is over in overlay cleanup. Due to this when destroying pipe, if pipe fetch halt tries to halt the pipe, kernel bug happens and system gets crashed. Hence, ensure pipes are unstaged before destroy.

| | | | | | | | | | | | | | | | | | MDP3 hardware on ferrum has the capability to send panic/robust signal to bimc based on fill level for DMA_P. This allows bimc to prioritize the MDP traffic.
