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.

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.

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.

For calculating bit rate in cphy, we multiply bit rate by a factor of
7/16 where 7 is the number of symbols and 16 is the bits per symbol.
But we are currently not considering the 7/16 factor while calculating
minimum bit clk value for command mode which is resulting in a smaller
bit rate value than the minimum bit clk.
Bit rate should always be greater than the minimum bit clk which otherwise
can lead to discrepancies. Correct minimum bit clk calculation for command
mode, by multiplying a factor of 7/16 if cphy.

When display is left on from the bootloader, disp_cc driver will put a
proxy vote on clocks to maintain the hardware configuration of bootloader.
Once all the consumers have been probed, the dispcc driver will synchronize
the hardware state of the device to match the aggregated software state
requested by all the consumers using sync_state call.
If there is an idle power collapse or a suspend before sync state call,
branch clocks and in turn RCG will not get turned off during clocks
disable sequence because of the proxy vote of disp_cc driver. This can be
the case even if there is a vote from any other disp_cc consumers.
During a subsequent call to enable the clocks from DSI driver, we are
currently switching RCG parent to PLL and then turning on the PLL.
If the sync state call doesn't happen before we enable the clocks back,
we'll be setting PLL which is off as a parent to RCG that is on.
But ideally when RCG is on, both the old and new sources should be on
while switching the RCG parent.
Avoid this by turning on the PLL before switching RCG parent during clock
enable sequence.
