Move the hist irq handling out of callback function, i.e., the hw
interrupt irq_lock context, to avoid dead lock between crtc spin_lock
and irq_lock. This change also extends crtc spin_lock coverage in
_sde_cp_crtc_enable_hist_irq to prevent null pointer dereference on
event node, which can be deleted during crtc event de-registration.

In CPHY, packet header and checksum is sent twice and SYNC is
sent in between two headers. So, increase packet overhead used
in clock calculation to 15 bytes. Packet Header: 8 bytes,
CRC: 4 bytes, SYNC: 2 bytes and dcs command: 1 byte.

sde_dbg_base in order to access the variable from ramparser

Add changes to fix the null dereference in
drm_atomic_get_property caused by connector->state
being NULL. This change allows the drm_mode_config_reset
operation to happen before drm_dev_register to avoid this.
In current scenario, connector->state->crtc is being
accessed due to call to drm_mode_getconnector ioctl with
the drm_mode_config_reset operation pending.

With WB encoder added in the drm encoder_list before primary
encoder introduced as part of commit d28ebf05f4 ("disp:
msm: sde: populate WB display encoder list before dsi"),
sde_kms_wait_for_commit_done during CWB usecase is causing
crtc_commit thread to wait for two WB frame done irqs causing
janks on primary. Add changes to unblock crtc_commit thread and wait
for only one WB frame done irq.

This change prevents scheduling of rc_restart in case of
panel dead. This early return is required to avoid the list
add corruption when a race condition happens between event
thread and commit thread. When event thread is handling
display failure notification if the virt_enable arrives in
commit thread it will reinizialize kthread for
delayed_off_work without deactivating the existing list
which leads to linkage corruption.

During dp altmode driver initialization, the dp altmode driver is called
with a null data packet. Even though this callback indicates a disconnect,
the multi function flag is incorrectly set to true. If the DP is enabled
later using simulation mode, the multi function flag is not cleared thereby
limiting the lane count to 2 irrespective of capability applied through
DPCD.
This change checks for the zero pin value while setting the multi function
flag.

In an MST DSC setup, the sink_dsc_caps object is read into the base
panel. In the process of creating different connectors and panel
objects, the sink_dsc_caps panel object is not copied correctly to
the new panel objects. This causes an error where a fallback DSC
version is used.
This change correctly copies the sink_dsc_caps object over to the
panel for the MST connector from the base connector.
