Boolean entry to enable esync. "qcom,mdss-esync-hsync-milli-pulse-width"
property should be set along with this property.

description: >
u32 entry to specify the skew between the esync signal and the timing
engine, in 1/1000ths of a pulse period. Example:
qcom,mdss-esync-milli-skew = <150>;
This would set the esync signal to precede the timing engine's output by
0.15 of a pulse period.

u32 entry to specify the pulse width of the hsync portion of the esync
signal, in 1/1000ths of a pulse period. Example:

This would set the esync line high for 0.75 of a pulse period, every hsync.

description: >
Array of 3-value tuples that describe the value of the
"qcom,mdss-dsi-qsync-freq-step-sequence" property.
Within each tuple, first value corresponds to the type of frequency
stepping sequence (0 for normal usecase and 1 for video usecase), second
value corresponds to the starting framerate for the sequence (in mHz),
and third value corresponds to the number of steps in the sequence.
qcom,mdss-dsi-qsync-freq-step-sequence:
description: >
Array of 2-value tuples that describe the framerate and duration of a step
in a sequence.
Within each tuple, first value corresponds to the framerate for this step
in the sequence, and second value corresponds to the duration in frames
of this step.
The tuples are arranged into groups defined by the
"qcom,mdss-dsi-qsync-freq-step-sequence-interval" property, which specifies
the length of a frequency stepping sequence in steps.
