msm: mdss: Reserve single SMP block for writeback mixer pipes

Writeback does not have stringent requirement for latency
buffers. So, SMP blocks reservation for the pipes attached
to writeback block can be restricted to single SMP block for
each plane. This makes more SMP block available for other
clients.

msm: mdss: Add SMP parameters into hw capabilites

To handle use cases better, expose smp_mb_cnt and
smp_mb_per_pipe to userspace as part of hardware capability.
Pipes availablity for a use case can be computed taking these
values, based on which, composition decisions can be made.

msm: mdss: optimize MDP pipes cleanup

There are cases where pipe cleanup can happen without display commit.
This means that the pipe was never programmed to hardware, in these
cases the pipe can be cleaned up without the need of display commit
cycle to happen. Also there is no need to access hardware to release
resources such as SMPs since they have not been programmed yet.

msm: mdss: implement overlay prepare ioctl

Overlay prepare will allow a full frame with multiple overlays to be
configured at once and perform frame level checks before being pushed to
display. This function guarantees that if the call is successful, the
frame can be displayed successfully on the screen when display commit is
called.

msm: mdss: Add SMP per pipe parameter into hw capabilites

Additional SMP parameter 'smp_mb_per_pipe' is required by

through sysfs node.

values, based on which, composition decisions can be made.

msm: mdss: Don't call pan_idle for MSMFB_OVERLAY_PREPARE ioctl

We keep calling MSMFB_OVERLAY_PREPARE for each composition
cycle, even if there are no changes in params. Because of this
we can hit performance degradation due to pan idle wait.
This change removes pan_idle wait for prepare call.

msm: mdss: refactor command mode vsync control logic

Current logic is prone to corner case when mdss_mdp_remove_vsync_handler
is called twice: once from mdss_mdp_cmd_stop and again from vsync ctrl
logic. Need to properly identify the second call and avoid resetting the
rdptr ticks which prevent from clocks being turned off properly.

msm: mdss: Sanitize overlay kickoff inputs

Overlay kickoff in certain situations can be called without a ctl

be captured and logical path should return safely.

msm: mdss: keep clocks on during kickoff operation

There is deadlock scenario where work thread to turn clocks off is
trying to acquire DSI's mdp_busy lock while holding clk_mtx to turn
mdp clocks on.  Meanwhile kickoff thread holds mdp_busy lock and
trying to acquire clk_mtx to turn on clock.
This patch ensure that clocks are kept on and work thread is not
scheduled while kickoff is in progress so that deadlock will not happen.
