be3415c620 drm/msm/dpu: Configure DP INTF/PHY selector 
Some platforms provides a mechanism for configuring the mapping between
(one or two) DisplayPort intfs and their PHYs.

In particular SC8180X requires this to be configured, since on this
platform there are fewer controllers than PHYs.

The change implements the logic for optionally configuring which PHY
each of the DP INTFs should be connected to and marks the SC8180X DPU to
program 2 entries.

For now the request is simply to program the mapping 1:1, any support
for alternative mappings is left until the use case arrise.

Note that e.g. msm-4.14 unconditionally maps INTF 0 to PHY 0 on all
platforms, so perhaps this is needed in order to get DisplayPort working
on some other platforms as well.

d3a785e4f9 drm/msm/dpu: take plane rotation into account for wide planes 
Take into account the plane rotation and flipping when calculating src
positions for the wide plane parts.

This is not an issue yet, because rotation is only supported for the
UBWC planes and wide UBWC planes are rejected anyway because in parallel
multirect case only the half of the usual width is supported for tiled
formats. However it's better to fix this now rather than stumbling upon
it later.

aedf02e46e drm/msm/dpu: move dpu_encoder's connector assignment to atomic_enable() 
For cases where the crtc's connectors_changed was set without enable/active
getting toggled , there is an atomic_enable() call followed by an
atomic_disable() but without an atomic_mode_set().

This results in a NULL ptr access for the dpu_encoder_get_drm_fmt() call in
the atomic_enable() as the dpu_encoder's connector was cleared in the
atomic_disable() but not re-assigned as there was no atomic_mode_set() call.

Fix the NULL ptr access by moving the assignment for atomic_enable() and also
use drm_atomic_get_new_connector_for_encoder() to get the connector from
the atomic_state.

df24373435 drm/msm/dpu: don't play tricks with debug macros 
DPU debugging macros need to be converted to a proper drm_debug_*
macros, however this is a going an intrusive patch, not suitable for a
fix. Wire DPU_DEBUG and DPU_DEBUG_DRIVER to always use DRM_DEBUG_DRIVER
to make sure that DPU debugging messages always end up in the drm debug
messages and are controlled via the usual drm.debug mask.

I don't think that it is a good idea for a generic DPU_DEBUG macro to be
tied to DRM_UT_KMS. It is used to report a debug message from driver, so by
default it should go to the DRM_UT_DRIVER channel. While refactoring
debug macros later on we might end up with particular messages going to
ATOMIC or KMS, but DRIVER should be the default.

2c92ca849f tracing/treewide: Remove second parameter of __assign_str() 
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.

This means that with:

  __string(field, mystring)

Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.

There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:

  git grep -l __assign_str | while read a ; do
      sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
      mv /tmp/test-file $a;
  done

I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.

Note, the same updates will need to be done for:

  __assign_str_len()
  __assign_rel_str()
  __assign_rel_str_len()

I tested this with both an allmodconfig and an allyesconfig (build only for both).

ca97fa419d drm/msm/dpu: Allow configuring multiple active DSC blocks 
Just like the active interface and writeback block in ctl_intf_cfg_v1(),
and later the rest of the blocks in followup active-CTL fixes or
reworks, multiple calls to this function should enable additional DSC
blocks instead of overwriting the blocks that are enabled.

This pattern is observed in an active-CTL scenario since DPU 5.0.0 where
for example bonded-DSI uses a single CTL to drive multiple INTFs, and
each encoder calls this function individually with the INTF (hence the
pre-existing update instead of overwrite of this bitmask) and DSC blocks
it wishes to be enabled, and expects them to be OR'd into the bitmask.

The reverse already exists in reset_intf_cfg_v1() where only specified
DSC blocks are removed out of the CTL_DSC_ACTIVE bitmask (same for all
other blocks and ACTIVE bitmasks), leaving the rest enabled.

2b938c3ab0 drm/msm/dpu: Always flush the slave INTF on the CTL 
As we can clearly see in a downstream kernel [1], flushing the slave INTF
is skipped /only if/ the PPSPLIT topology is active.

However, when DPU was originally submitted to mainline PPSPLIT was no
longer part of it (seems to have been ripped out before submission), but
this clause was incorrectly ported from the original SDE driver.  Given
that there is no support for PPSPLIT (currently), flushing the slave
INTF should /never/ be skipped (as the `if (ppsplit && !master) goto
skip;` clause downstream never becomes true).
