Currently dynamic mode-switch is allowed only after
the cont-splash handoff is handled during the first
frame. Remove this restriction for cmd-mode alone as
it can handle the use-case.

Primary and secondary displays should have first priority
when reserving lms. Static reservation can potentially block
higher resolutions for the required displays. This patch gets
the layer mixer requirement for primary or secondary display
if available. It reserves those layer mixers dynamically
for the respective display when connector is registered.

Add support to selectively enable clock gating for supported
DSI clocks using a new debugfs node - config_clk_gating. This
new node would be created for every display node. See below
for usage examples:
To enable clock gating only for BYTE clock:
echo 1 > /sys/kernel/debug/<display_name>/config_clock_gating
To enable clock gating only for PIXEL clock:
echo 2 > /sys/kernel/debug/<display_name>/config_clock_gating
To enable clock gating only for PHY clock:
echo 4 > /sys/kernel/debug/<display_name>/config_clock_gating
To enable clock gating only for all clock:
echo 7 > /sys/kernel/debug/<display_name>/config_clock_gating
To disable clock gating for all clocks:
echo 8 > /sys/kernel/debug/<display_name>/config_clock_gating
To go back to default setting:
echo 0 > /sys/kernel/debug/<display_name>/config_clock_gating

If we set esd check mode as TE signal check for video mode panels
the panel will be continuously reset. This change doesn't allow
TE signal check as ESD check mode.

This change fixes the invalid memory access. It allocates
enough memory so that out of bounds access is avoided.

Change updates dsi clock calculations for command mode
as per recommendation. Now dsi clocks are tied to
frame transer time. Propagate correct frame transfer
time to hal to update mdp clocks and bandwidth needed
accordingly.

DSI display may support video mode and command mode both and it may
support transition between these two modes.
This change adds seamless transition between these two modes for DSI
display by avoiding crtc enable/disable and panel power on/off
during modeset.

Add runtime_pm ops support in drm driver instead
of direct sde_power_resource_enable/disable call.
It allows drm driver to use runtime pm refcount logic
to track the resources instead of custom implementation.
The change also removes the NRT_CLIENT support from
sde_power_handle code to simplify it further.
