* | | msm: mdss: check intr line status before handling isrDhaval Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware might return/call the pending interrupt on one CPU when same interrupt is disabled from other core. Such parallel processing may lead to unclocked register access in interrupt context followed by panic. It is safe to check the interrupt line status before handling isr to avoid crash in such race condition.

* | | msm: mdss: fix deadlock between display and ESD check threadRay Zhang2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Display thread holds ov_lock followed by mutex, while the ESD check thread for cmd mode panel holds mutex followed by ov_lock. Fix this deadlock by acquiring mutex before ov_lock in ESD check thread. Change-Id: I857f780e14a6ccb679e89ff16b19706d205df4b6 Signed-off-by: Ray Zhang <rayz@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Send stream management message to sink after topology update. Poll for new message or authentication required status after successful receiver or repeater authentication. Also, DDC hardware polls sink for a given time. Let the polling complete and do not treat intermediate DDC errors as failures because DDC transaction can pass in next iteration. Once polling ends, check for errors and timeouts and reset polling data. Treat these errors as failure only after polling ends.

* | | msm: mdss: maintain AD state through idle power collapsePing Li2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When device enters the idle power collapse mode, the entire AD HW block is powered down, which will cause the previous AD settings get lost. So when device exits the idle power collapse mode, we need to store AD to previous state. In order to achieve this, we need to switch AD mode to 0x85 first and manually write the last AD strength value to AD register. Keep this setting for couple of frames, in the meantime, kick off AD calculator with t_filter_control value of 0 to ramp up the AD strength from 0 to current target strength. Then switch the mode back to auto strength (0x81). Change-Id: Iddc12dbb0da06675141fa9fe049cfe90110defb9 Signed-off-by: Ping Li <pingli@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reset the ad_events count in the AD ioctl instead of ad_setup(). There are some time delay between AD ioctl and ad_setup, which is part of the display commit path, so if we reset the ad_event count in ad_setup, then it is possible that user space reads the ad_events sysfs node after the AD ioctl but before the ad_setup(). In that case, user space may get the incorrect ad_events count, and cause the gradual AD off fail. Change-Id: I13f2043a6a21be7e49b44a964b00b0aa4315dc17 Signed-off-by: Ping Li <pingli@codeaurora.org>
* | | msm: mdss: add multiple register support in ESD checkRay Zhang2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation cannot support multiple registers in ESD check, and it does not work for many cases. For example, some panels need check multiple registers to get its status, and some panels might return several possible values for one register read. To support this kind of behaviors, a new property in dtsi is added as "qcom,mdss-dsi-panel-status-valid-params" which specifies the valid value length we should check in the payload returned by panel, and the payload length panel should return is specified by the property "qcom,mdss-dsi- panel-status-read-length". "qcom,mdss-dsi-panel-status-value" is also extended to an array which specifies all the possible return values from panel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The backlight of the display panel will not get turned off during suspend if there are no display commits between suspend/resume since allow_bl_update will only be set to 'true' after first valid display commit after resume. This is possible for power off charging use-case where there will be only one display commit initially and later just the content of the buffer gets updated without anymore display commits across suspend/resume. Make sure the backlight is turned off during suspend by explicitly setting allow_bl_update to 'true' before trying to set the backlight to zero.

* | | msm: mdss: move used pipes to cleanup list on overlay freeVeera Sundaram Sankaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid moving pipes to destroy list during overlay free based on the pipe play count as it might not give the actual information. The play count is set to 0 for all new or config changed pipes during the validate call. And if we get a fb_release_all request right after the validate, it would indicate an inconsistent state for the play count. Instead, move the used pipes to cleanup list, so that the NULL kickoff would handle the pipes to be unstaged and destroyed.

* | | msm: mdss: hdmi: schedule link work from isrAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not schedule link work periodically to check for new message or authentication status. Hardware automatically poll sink for the same. Once new message is available or sink indicates re-authentication required, isr is triggered. Queue link check work from isr to avoid unnecessary software polling. Change-Id: I83c71f5151aa077e863b6578a89f6515f6497159 Signed-off-by: Ajay Singh Parmar <aparmar@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide user an option to let the HDCP2.2 authentication run on main thread. Avoid processing on module threads thus avoiding any scheduling delays. The user may choose to switch to this mode based on its requirements.

* | | msm: mdss: hdmi: clear ddc line before starting hdcpAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clear DDC line if scrambling and Rx status polling is still going on. Check for all scrambling and Rx status errors and stop polling in error cases. This needs to be done before new hdcp authentication session is started to avoid any authentication failures because of ddc line being busy.

* | | msm: mdss: update DSI PHY panel timing dt parsing logicSandeep Panda2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current implementation there are two entries in DSI panel specific dt file for specifying panel timing parameters. But in case only one entry is specified in panel dt, then if the first entry is not there in dt, driver is returning failure and because of this the second entry is not getting parsed at all. Update the parsing logic so that driver parses both the entries to get proper dsi panel timing parameters.

* | | msm: mdss: hdmi: update hdcp information at hdcp startAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the hdcp related information when hdcp is started and not before that. Updating hdcp information depends on some modules which may not be ready during boot-up resulting in hdcp failure. Update hdcp information on user thread to make sure that kernel has completed boot-up and dependent modules are ready.

* | | msm: mdss: hdmi: check clk state before power onAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clocks should be enabled and running at proper rates before powering on hdmi transmitter. In fast plug in/plug out of hdmi cable cases or fast suspend resume cases, there can be a race condition related to enable/disable of clocks and hdmi power on/off. Make sure, in such corner cases, hdmi transmitter core is not being programmed to avoid any possible un-clocked register access issue.
