description: >
Specifies the dsi transfer time for command mode

the clock rate according to the expected transfer time.
Increasing this value would slow down the mdp processing
and can result in slower performance.
Decreasing this value can speed up the mdp processing,
but this can also impact power consumption.
As a rule this time should not be higher than the time
that would be expected with the processing at the
dsi link rate since anyways this would be the maximum
transfer time that could be achieved.
If ping pong split is enabled, this time should not be higher
than two times the dsi link rate time.
If the property is not specified, then the default value is 14000 us.

threshold time, which has a default value in chipset

sde-dp is the master Display Port device which supports DP host controllers that are compatible
with VESA Display Port interface specification.
msm_ext_disp is a device which manages the interaction between external
display interfaces, e.g. Display Port, and the audio subsystem.
[Optional child nodes]: These nodes are for devices which are
dependent on msm_ext_disp. If msm_ext_disp is disabled then
these devices will be disabled as well. Ex. Audio Codec device.

description: |
Specifies the dsi transfer time for command mode
panels in microseconds. Driver uses this number to adjust
the clock rate according to the expected transfer time.
Increasing this value would slow down the mdp processing
and can result in slower performance.
Decreasing this value can speed up the mdp processing,
but this can also impact power consumption.
As a rule this time should not be higher than the time
that would be expected with the processing at the
dsi link rate since anyways this would be the maximum
transfer time that could be achieved.
If ping pong split enabled, this time should not be higher
than two times the dsi link rate time.
If the property is not specified, then the default value is 14000 us.
