* | msm: mdss: add support for dynamic dsi phy timing calculationJeevan Shriram2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The programming of the DSI Phy timing registers are dependent on link frequency. In the current implementation, these values are pre-computed statically based on the link rate required for a particular panel. This approach does not scale very well, especially for use cases when dynamically changing the refresh rate or resolution for a panel. To address this, add support to dynamically compute the value for dsi phy timing registers based on a particular link rate.

* | msm: mdss: fix split_mode setting during mode switchVeera Sundaram Sankaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | During mode switch, split_mode was set to pp split by checking if the panel is in split_mode and MDP supports pp split. This leads to faulty configuration as pp split should be set only when the panel setting has pp split and MDP support it. Add proper checks to set the split mode correctly.

* | msm: mdss: fix backlight update between unblank and kickoffDhaval Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The backlight update between unblank and kickoff call may result in garbage/snow screen on panel based on panel ram initialized status. For ex: -> Unblank the panel - black frame transfer start, panel is on but ram is still uninitialized. -> backlight update - turn on the backlight. It will show data from uninitialized ram because frame transfer is not complete yet. This can be avoided by blocking the backlight update request between unblank and first frame kickoff. This gives guarantee that panel has valid data to display when backlight was turned on. Change-Id: I09c707cd10acd53bd6aa0935885269ffc5aec649 Signed-off-by: Dhaval Patel <pdhaval@codeaurora.org>

* | msm: mdss: update mixer pipe_mapped value during overlay_offVeera Sundaram Sankaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The pipe_mapped and pipe_next_map are used to keep track of the pipes staged in the mixer. The former is used to keep track of the pipes which are currently used by the hw while the latter keeps track of the pipes staged for the next frame. During overlay off, this seems to be off track as only the pipe_next_map would have the updated status and both would be in sync only after the next commit cycle. This would cause the mixer to check for invalid pipes during the ctl_stop. Fix the pipe_mapped state to have the current staged pipes during overlay_off.

* | msm: mdss: pass file pointer as argument to fb_ioctl apiDhaval Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MDSS driver uses file pointer to track the client and associates the resources based on it. There can be a race condition between to clients ioctl call and it can lead to track resources with wrong caller. This can leads to release/reallocate resources prematurely to other client which may show blank screen on display. One good example client call flow is: <-step:1-> fb_open by client-X <-step:2-> fb_open by client-Y <-step:3-> fb_ioctl by client-X <-step:4-> fb_ioctl by client-Y <-step:5-> fb_ioctl by client-X <-step:6-> fb_close by client-Y If step-5 and step-6 both are running on two different CPUs at same time then it may overwrite the file node unintentionally. This change tries to pass the file pointer as one of the argument to IOCTL call. It avoids usage of mutex lock to support the concurrent calls.

* | msm: mdss: do not skip pipe programming if roi changedUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | Current driver has an optimization where if pipe parameters are not changed between consecutive updates then it will skip pipe's HW register programming. However when partial update is enabled and ROI is changed compared to previous update, pipe's HW programming should not be skipped because HW is programmed with stale ROI for that given pipe. Fix this by forcing pipe HW programming update if ROI is changed. Change-Id: Iebff043ecbb35b22ffbe344bdffa830602437252 Signed-off-by: Ujwal Patel <ujwalp@codeaurora.org>
* | msm: mdss: fix dsi underflow during partial updates on DSC based panelsUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When 2 soft slices per DSC encoder without merge is used, HW expects certain DSI pixel clock to MDP clock ratio. If not maintained, DSI can underflow. This happens if full-frame is split into 4 slices, thus requiring 2 DSC encoders, 2 soft slices per encoder. Now if partial update frame is left-only or right-only with 2 slices then normal topology would dictate using 1 DSC encoder with 2 soft slices. However during partial update, we don't change the pixel clock, but mdp clock is reduced because less number of pixels needs to be processed. This changes the ratio mentioned earlier and DSI underflows. To fix this, either we increase the MDP clock rate or change the topology such a way that we use 2 DSC encoders with 1 slice each. Implement later option to avoid increasing MDP clock. Change-Id: Ia37d8045baefcd1e680902446b4725d279db6a89 Signed-off-by: Ujwal Patel <ujwalp@codeaurora.org>
* | msm: mdss: enable right-only update on DUAL_LM_SINGLE_DISPLAY split modeUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Any smart panel with DUAL_LM_SINGLE_DISPLAY split mode with support for partial update requires runtime topology changes when update is using only one layer mixer. Specifically, when right-only partial update is needed, MDP topology needs to switch to ping-pong associated with right layer mixer and disable left layer mixer path. Add changes to support these use-cases dynamically. Now when Display Stream Compression (DSC) is used with this split mode, there are certain restriction from HW when switching from left+right update to right-only update. During such scenarios we cannot use right layer mixer based data path and have to use left layer mixer based data path. Add quirk based logic to use this mode.

This result in ESD being disabled sometimes when we coming out of ambient mode. Hence set esd_rdy to true once during bootup and never set this back to false.
