Use #if IS_ENABLED() instead of #ifdef for configurations as vendor module
guidelines.
Use #if IS_ENABLED(CONFIG_XXX) instead of #ifdef CONFIG_XXX to ensure that
the code inside the #if block continues to compile if the config changes
to a tristate config in the future.
The differences are as follows:
1.#if IS_ENABLED(CONFIG_XXX) evaluates to true when CONFIG_XXX is set to
module (=m) or built-in (=y).
2.#ifdef CONFIG_XXX evaluates to true when CONFIG_XXX is set to
built-in(=y) , but doesn't when CONFIG_XXX is set to module(=m).
Use this only when you're certain you want to do the same thing
when the config is set to module or is disabled.

As per the HW requirements it is highly recommended to use DMA start window
to trigger broadcast commands. If not used then it can result in a hardware
hang with the DSI controllers going out of sync. This behavior is even more
prominent in cases of higher refresh rates.
Currently, reset_trigger_controls is called as part of next command.
Due to this, when unicast command is sent after broadcast command,
reset_trigger_controls does not get called for slave controller,
leading to issues.
As part of this change, DMA start window scheduling is enabled as default
for broadcast commands and reset_trigger_controls is done as part of
post_cmd_transfer operations.

During a force update of DSI clocks, the state of the byte and pclks are
toggled irrespective of the ref-count. This in addition with ASYNC
command wait can result in interrupt storm, if and when the clocks are
being toggled a previous command that was triggered using the ASYNC
wait flag fires an ISR. The interrupt status doesn't get cleared if
the ISR is being serviced with the clocks are off.
The change adds a check for pending queued commands before any force
update of DSI clocks.

In transfer-time calculation remove fixed prefill lines assumption
and consider max of default prefill lines and prefill lines specified
from the panel timing info.
For panels with higher porches exceeding default prefill lines
alternate framedrops can occur if transfer-time exceeds RSC static
waketup time as actual prefill lines are considered in RSC static
wakeup timer calculation. This change ensures transfer-time is with
in RSC static wakeup time.

Currently, in dsi_display_get_modes, priv_info, rates,
front_porches and pixel_clks_khz memory is allocated for each
timing node and the same memory is copied for each supported fps.
The values of front porches calculated to maintain constant fps for
each bit clk rate gets overwritten with the values for last fps in
the dfps list. But the values of front porches should be different
in case where DFPS and dynamic clock are both supported either by
vfp approach or hfp approach. To fix this, allocate memory
separately for each fps.

In ASYNC wait mode, next command kickoff can happen before previous command ISR execution is
completed in below sequence:
ASYNC command A -> triggered
dsi_ctrl_isr for command A -> fired and executed atomic_set(&dsi_ctrl->dma_irq_trig, 1);
wait_for_done for command A -> returns early as dsi_ctrl->dma_irq_trig is 1
ASYNC Command B -> triggered
wait_for_done for command B -> waiting for cmd_dma_done
dsi_ctrl_isr for command A -> executes complete_all(&dsi_ctrl->irq_info.cmd_dma_done);
wait_for_done for command B -> returns success incorrectly based on complete_all of previous
command isr and disable_status_interrupt() is not called.
This leads to refcount of dma_done going wrong and dsi_ctrl_isr is not enabled on suspend resume.
To fix this issue, mark command transfer successful only based on complete_all(cmd_dma_done). This
way disable_status_interrupt() will be always called either from dsi_ctrl_isr or wait_for_done().

After an ESD failure, the PHY lanes and controller can be stuck in
an unknown state. This can result in interrupt storms and watchdog
failures, if these error states are not handled correctly. The following
change implements the below mechanism to avoid failures.
1) Disable error interrupts during an ESD reg read, which are re-enabled once
ESD check is successful.
2) On ESD failure, before turning off LP clocks, reset the PHY lanes and DSI
controller.
3) After the HS clocks are turned off, issue a PHY hard reset.
4) Before enabling/disabling error interrupts, clear the error status registers
as they are not cleared as part of controller reset.
