* | msm: mdss: fix the input layer and layer list array indexJeevan Shriram2016-03-23
| | | | | | | | | | | | | | | | | | | | In the current implementation, wrong memory is being referenced while copying to user. Correct the input layer and layer list array index to avoid invalid memory access.

* | msm: mdss: use usleep_range instead of msleep in mdss utilClarence Ip2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | qcom: msm: event-timer: Add eventimer migration frameworkMurali Nalajala2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, all the event timers are associated to CPU0. These event timers are not bind to any of the IRQs and always handled(hrtimer) by CPU0. This event timers framework make sure event timers are bound to clients IRQs and when the IRQ affinity has changed event timer framework will make sure to move associated event timer to a new CPU based on IRQ affinity.

* | msm: mdss: fb: remove check for allocated during resolution switchAdrian Salido-Moreno2016-03-23
| | | | | | | | | | | | | | | | | | | | | | 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.

In cases where we want to reprogram the values in the hardware, there is the possibility of corruption. This change forces the mixer setup to skip GC programming if it is currently enabled.

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.

* | msm: mdss: release ahb clocks when mdp clocks are released.Ingrid Gallardo2016-03-23
| | | | | | | | | | | | | | | | | | | | | | This change makes sure that all the clocks held by the display driver gets disabled when the mdp clock is also released and will switch the ahb vote to active-only context, so the bus driver can also free all the unneeded clocks when cpu is not active.

* | msm: mdss: switch mdp context between active-only and active+sleepIngrid Gallardo2016-03-23
| | | | | | | | | | | | | | | | | | This change modifies MDP vote to go to Active-Only in an early stage when bandwidth is not needed and updates the vote to Active+Sleep when bandwidth must be guaranteed.

* | msm: mdss: prevent power off iommu if handoff is still pendingIngrid Gallardo2016-03-23
| | | | | | | | | | | | | | | | | | | | | | When continuous splash handoff is still pending, is not needed to enable/release the iommu, since clocks and iommu are already refcounted and enabled. Add a check so by the time that aplash screen is still on-going, we do not release the iommu.
