In DPSIM, while calling the hpd callback from dp_sim_host_hpd_irq,
the hpd argument is passed in as false. In the hpd callback, both
the hpd_irq and hpd arguments need to be encoded into the vdo
parameter. Currently, MST DPSIM testcases are broken because this
is not implemented properly.
This change sets the hpd argument to true in the hpd_irq callback, and
encodes the hpd and hpd_irq parameter in the vdo object before passing
it to the simulate_attention callback.

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.

The order of the panel timing nodes specified in the device tree is
not guaranteed to be the same while being parsed in the driver. This
results in unintended modes being set as preferred timing mode. The change
introduces cell-index property, so that the timing modes can be
accurately indexed and parsed.

DSI display configuration can be either DT or firmware file driven.
When probed with firmware path, asynchronous firmware file read
callback function will be too late to check for dependencies and
defer the probe when the dependencies are not met.
Move all the dependency checks before the firmware file read request.
Since the panel data will not be available before the DT/firmware read,
this change limits the check to the dsi display layer.

Currently, 4K120 mode is being filtered by DP driver
due to invalid topology assignation. When 4 LMs are
needed, the number of DSCs must match the number of
LMs since only DSCMERGE based topologies are supported
for driving DSC capable panels.
This change fixes the topology validation logic and
aggregates LM and DSC validation functions in the topology
one since the number of LMs and DSCs must now be considered
in calculating the topology requirement.

Currently, SDE_DBG_DUMP takes any number of hw block names along with
few defined strings as arguments. This set of arguments is used to
determine which HW block registers needs to be dumped. Move to a
blk bitmask to avoid passing a large set of arguments. The bitmask is
split based on the clks required to access the HW block for ease of use.
The lower 0-23 bits are used for HW blocks which can be accessed by just
enabling the MDP clks. DP is kept separate as it needs DP specific
clks to be enabled. Add a debugfs node through which the mask can be
modified, which can be useful while using the debugfs dump option to
force a panic.
As part of the change, remove in-log/in-mem enable mask debugfs node
for every debugbus and use a single node to control the logging
mechanism for all the HW blocks debugbus.
