Add a flag SDE_DBG_DUMP_IN_LOG_LIMITED based on which the debug bus
registers dumped in log can be limited. In memory logging will continue
to dump the full range of configured registers if that flag is set.
Currently the in-log limited support is enabled only for the sde/vbif
debugbus and both IN_LOG & IN_LOG_LIMITED will be treated the same way
for other blocks.

Refactor the debugbus read/logging for sde/dsi/vbif/lutdma to use the
same helpers. Use function pointers to read/write specific hw block
operations. Remove the DBGBUS_FLAGS_DSPP and related checks as it is
not used. Increase the debugbus block/test-point ranges for all the
blocks to log all the test-points used by hardware.

During mode enable after idle, rsvp next would be set without
rsvp cur. Back to back test only should be serialized, but currently
this would be possible right after idle. This is established by
commit 11aab5f9c3 ("disp: msm: sde: Fix null dereference errors").
This change updates the condition to poll for rsvp next clear
during this usecase as well.

This change allows signalling of sde fences when sequence number is

the status causing the UI thread to block on sde fence.

Some panels may require that the DSI link returns to the low-power
stop state (LP11) after transmission of every line. If a panel
requires that the DSI link returns to LP11, apply the LP11
insertion between lines feature.
This change adds support to
- Disable the command mdp burst mode
- Enable mdp idle ctrl
- Program the No. of dsi pclk cycles of idle time to
insert between command mode mdp packets. The idle time
must be long enough to cover the time link takes to
switch between HS to LP11 mode.

Imbalance power vote caused with below scenario:
1. Primary display running with CWB enabled.
2. Idle-PC has kicked in causing primary and cwb encoder to rc_idle state.
3. Post idle-PC with DMS switch enabled along with CWB.
Changes made are to avoid pre_modeset and post_modeset callbacks
for CWB encoder as it not required and it puts a unnecessary power
vote causing power issues in suspend usecase.

Add changes to set CTL id preference for primary and secondary
builtin displays. This change check for preference if already set
from DT. If not preference will be set during connector init.
This avoids CTL datapath switches on secondary when there is dual
display usecase running concurrently with dp connect/disconnect.
In current issue scenario, due to the secondary ctl datapath
switch CTL_LAYER programming is happened on CTL_2 but CTL_FLUSH is
happened on CTL_1 causing pp_done timeout issues.

This change avoids upstream drm issuing drm_atomic_commit in
drm_fb_release which is leading to artifacts on screen or
atomic_check failures due to atomically unstaging each fb
from plane_state and committing remaining planes on hardware.
a) This patch moves the state operations for setting crtc to
connector state to a helper api.
b) This patch clears any dim_layers present in the crtc_state
as part of null commit.
c) This patch removes any framebuffers attached to a drm_file
in msm_preclose whose refcount is not managed by composer kill
inadvertently and issues null flush to hardware in such cases.
d) This patch handles msm_preclose as part of msm_release
operation since legacy feature is not supported
for msm_driver.
