Display in trusted VM works in a handover mode i.e, all
display components need to be initialized by the primary VM
before switching to trusted VM on the usecase boundary.
That makes it a hard requirement for the trusted VM not to
re-program any of the display configuration registers before
it could hand the HW back to the primary VM.
Also, most of the linux framework drivers including pintrl, clocks
are not enabled in the trusted VM.
In order to address the above two limitations and to control the
probe/commit sequences, this change adapts the same path as that
of continuous splash to bypass some of the critical functions
which are identified to be HW intrusive. Based on the DT property
read from SDE handle, dsi drivers will choose to bypass
enable/disable HW state updates when executing in the vm environment.

Avoid sharing and have dedicated dsi HW ctrl ops across versions
even if they are identical. It helps to stub out a specific

Trusted VM will be granted access to MDSS HW dynamically on
usecase boundary. As a result, all the attempts to access
HW before the assignment, including the probe time access
will result in Stage 2 faults. This change skips the
PLL clock registration during probe as the clocks will not
be controlled by the VM.

This change implements a new feature to read the cmds response
of the panel from sde connector interface. Sde connector opens
debugfs interface for all the connectors those have support for
cmd receive operation.
Sde connector init module creates rx_cmd debugfs file at
/<debugfs-root>/dri/0/DSI-1/ for DSI-1 connector.
Format for DSI command transfer:
echo "command bytes" > /<debugfs-root/dri/0/DSI-1/rx_cmd
byte-0: the length of received buffer
byte-1: data-type
byte-2: last command. always 0x01
byte-3: channel number
byte-4: flags. MIPI_DSI_MSG_*, must be set to 0xa
byte-5: 0x00
byte-6 and byte-7: command payload length
byte-8 to byte-[8+payload length]: command payload
Example:
echo "0x01 0x06 0x01 0x00 0x0a 0x00 0x00 0x01 0x0a" > rx_cmd
The command receive operations are allowed only if controller
(ex. DSI controller) is in active state.
Read the value of panel response:
cat /<debugfs-root>/dri/0/DSI-1/rx_cmd
returns the value of this command.
nothing - failure, xx xx - success.
