* msm: mdss: debug: add additional debug bus probe points for 8996Ujwal Patel2016-03-23
| | | | | | | | Add additional debug bus probe points for 8996 to aid in the critical debugging involving MDP related crashes. Change-Id: I6e72062d7bc5fc25e44358363326e3192705511b Signed-off-by: Ujwal Patel <ujwalp@codeaurora.org>
* msm: mdss: double check WB done statusKrishna Chaitanya Devarakonda2016-03-23
| | | | | | | | | There are cases when WB done might be set in MDP HW but the irq trigger is delayed. Add an additional check in case of WB timeout, to check if the WB done is set.

* msm: mdss: allow get_metadata when the panel is in suspend modeVeera Sundaram Sankaran2016-03-23
| | | | | | | | | | There are scenarios when HAL retrieves information through get_metadata when the panel is in suspend mode. Allow the get_metadata ioctl to go through, even when the panel is in suspend state.

| | | | | | | | | | On latest MDP revisions where there is support for double buffering of timing generator registers, it is not needed to check for MDP line count while updating the fps.

| | | | | | | | | | | | | msleep API runs in atomic context and can add extra delay after sleep timeout. This can add extra delays for panel regulator turn on/off sequence which affects device suspend/resume timing. Moving to usleep_range enables the delay backed by hrtimers.

| | | | | | | | | | | While switching resolution the fb memory requirement may increase and the current memory may not be able to support the new resolution. However since we can still go through overlay path, this requirement shouldn't be mandatory. Allow it to go through, there are enough checks during mmap to fail if trying to use this memory.

| | | | | | | | | | When DSI underflow is reported, ctl reset is preformed which requires certain critical regions to be protected by mutex. However this reset itself doesn't need to be protected by koff_lock spinlock and thus move it out of spinlock to prevent mutex locking while holding spinlocks.

* mdss: mdp: fix pipe/mixer stage information during freeDhaval Patel2016-03-23
| | | | | | | | | | | | | | | | MDSS driver stages the pipe on certain mixer but does not update the stage index to unused after un-stagging the pipe from kickoff. It is better that pipe free api checks the mixer stage before setting pipe mixer null. This helps to catch the bugs where pipe is getting staged without commit call. This change tries to update the pipe free API with proper error checks. It also avoids mixer free twice from ctl destroy to avoid error messages at each suspend/resume.
