In non-qsync panels when min FPS is not published in DT,
the default min fps is set to 10 FPS. This change handles mode
switch cases, when panel FPS drops below 10 FPS by updating
min FPS to panel FPS for Expected Present Time calculations.
As part of the change, reduce 2ms from EPT to account for
scheduling delays after schedule_timeout.

Currently we are always doing command transfer cleanup which includes
disabling command engine, clocks, gdsc and unmasking overflow interrupt
as part of post command transfer function only after CMD DMA wait is
done. Cleanup should also be done if an ESD failure happens before
kickoff of a batch command. Organize code so that command transfer
cleanup can be done irrespective of whether command kickoff is done
or not.

Reset number of bytes read from panel to the expected value when panel
sends more bytes than requested during DSI read. This can otherwise lead

Qsync ON/OFF commands have to be sent to the panel before connector
kickoff and sending them in the commit thread blocks it for few
millliseconds, and can lead to frame drops. Avoid this by sending
them asyncronously.

With DP plug-ins, it is possible for the connector fill modes API
to be called to update available modes on the connector and at the
same time have the commit thread calculate the max mode width
on the available modes. As a result, it is possible to access
pruned modes from the modelist.
This change moves the calculation into the fill modes call-flow,
so that the max mode width is determined once, and stored to be
used during virt enable.

The llcc_slice_getd/putd APIs were previously used to get/put the
slice descriptor reference, for every time the driver needed the
descriptor. However, the APIs should be used to get the reference
once, and only put after completing usage of the slice
(ie. if the slice is still active, the descriptor cannot be putd).
This change corrects the usage of the llcc_slice_getd/putd APIs by
storing the descriptor after initialization.

This reverts commit ae24e846e1.
Enable the feature only when user-mode support is added. With this
feature enabled in driver, it expects EPT_FPS to be set for qsync
enabled cmd-mode panels and will not honor EPT(expected present time).
With the EPT_FPS feature disabled, all panels cmd/video with/without
qsync can use EPT.

Update vcpi start slot for other connectors when an individual connector is unplugged.
Currently the driver is caching the previous start slot and doing the adjustment
in a single pass. When the connectors are removed and added in a specific order,
it is possible that the list of payloads are not sorted by start_slot and the
removed payload is not the first payload in the list.
The current logic does not support this case and will leave the start_slot of
the first payload unadjusted thereby resulting in an invalid slot allocation.
This change does the caching and adjustment in two separate passes to make sure
the start slot adjustment happens irrespective of the order of the payloads.

In dual display configuration, where only one display is active at a time,
dsi0 and dsi1 can be used to drive primary large display and, one of the
dsi (dsi0 or dsi1) can be used to drive secondary display. This helps to
time division multiplex shared DSI for primary and secondary panel which
solves the bandwidth limitation problem. This change adds support to allow
sharing of dsi ctrl and phy between dual displays.

During atomic check for MST plugins, the driver is not catching and
propagating failures properly thereby incorrectly returning a
success even though the slot allocation had failed. This causes
invalid access of payload data in the MST topology manager.
This change checks the return code for slot allocation and atomic
check calls and propagates them to caller.

The clk_ctrl_cb and post_cmd_tx_workq callbacks are assigned
to individual ctrl during display bind. In case of dual display
with shared DSI, where primary display has ctrl0 & ctrl1 and
secondary display has ctrl1, the callbacks of ctrl1 of the
primary display gets overwritten with the callbacks of ctrl1
of the secondary display.
In the shared DSI design, only one display will be active at
a time. So, move the callback assignment of clk_ctrl_cb and
post_cmd_tx_workq to display prepare to fix this.
