* | msm: mdss: phy_sw_reset both dsi controllers at same timeKuogee Hsieh2016-03-23
| | | | | | | | | | | | | | | | | | During split display case, the 2nd dsi ctrl's phy/pll registers are programmed at same time as 1st ctrl programmed since both controller share pll0. Therefore they have to be reset at same time also. Change-Id: Ifb2007c4efd619cd5f08a0fc64fd66f22d62efcd Signed-off-by: Kuogee Hsieh <khsieh@codeaurora.org>
* | msm: mdss: hdmi: optimize DTD resolution parsingAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | DTD (Detailed Timing Descriptor) provides full resolution timing details. Currently we compare these details with our resolution data base to find a match. This is not needed as DTD has complete details. Once parsing of resolution is done, just add this as a new resolution.

* | msm: mdss: prevent excessive logging after shutdown requestedUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current frame-buffer driver gets shutdown call back and it turns the display off. Once shutdown call-back is received, any subsequent frame-buffer opens are rejected and an error log is generated. Now user-land display clients are not aware of shutdown and they keep opening the frame-buffer devices repeatedly ignoring the failures and notifications sent by the driver. Due to this, excessive logging is observed which in turn leads to watch-dog bite and a crash. Prevent this by generating error log only once and keep sending sysfs notification for every rejected frame-buffer open.

* | msm: mdss: add a fb type for fb mmap ioctlMao Flynn2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using fb mmap, we can get a buffer from ion handle, or from a fixed adress physical continuous memory. Earlier if mmap is called more than once then ion handle won't be NULL and fb would allocate using physical continuous memory. Fix this to ensure the type of fb allocation is correct by storing fb map type.

* | msm: mdss: fix dts_x modifications for atomic commit ioctlsUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting new atomic commit IOCTL implementation, driver expects user-land to send each input layers's destination x in full panel co-ordinate system unlike previously this was required only when source-split feature was enabled. As an example, in dual-dsi configuration where each panel is of 1280 width then any layer going to only right panel needs to have their dst_x at-least 1280. Now internally driver manipulates this if source-split is enabled or not. However current implementation sends back this modified dst_x backs to user-land which in turn comes to driver in subsequent IOCTL calls and leads to unexpected behaviour. Fix this by sending original dst_x back to user-land program. Change-Id: I962cfa15e4dc7e905e42330f808edb31d33ffdf2 Signed-off-by: Ujwal Patel <ujwalp@codeaurora.org>

* | msm: mdss: hdmi: proper synchronization between hpd and tx powerAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, HDMI driver has HPD (Hot Plug Detect) work to handle HPD interrupts and power off work to handle the Tx power off. Power off work waits for HPD work to finish if in progress. In case of suspend, this can lead to a dead lock or power off work might starve for long time HPD work may take some time to finish resulting in suspend or next resume to timeout. Power off work was added to unblock the user thread as it used to take a long time waiting for audio engine to finish. That part of the code has been moved to HPD work. Now power off can be synchronous with the call as now it doesn't account for the delay. This removes the dependency on other work. Also, use a separate mutex for power on/off. The existing mutex is being used in large number of places which are not related. During suspend/resume use of mutex in places like sysfs read/write might result in longer hold of the mutex resulting in power off delay which eventually may timeout the suspend or resume.

* | msm: mdss: hdmi: give multiple resolution info using sysfs nodeAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | Provide complete resolution details in a sysfs node "res_info" limited to PAGE_SIZE. Different modules can query for multiple resolution details based on the resolution ids received from EDID of the TV. In case resolution details exceed PAGE_SIZE, reuse res_info to get remaining timing details by provide page details.

* | msm: mdss: hdmi: optimize resolution data baseAjay Singh Parmar2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDMI has a large number of resolutions supported and currently for all supported resolutions, related modules maintain static tables which are populated at boot time. This results in huge static memory usage. Also, it limits the system to support only the define resolutions. Remove static table which stores all the resolution details. Get individual resolution details on need basis. Also, remove the dependency to support only the defined resolution. HDMI driver can support any non standard resolution within the allowed range.
