+- qcom,mdss-mdp-transfer-time-us: 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 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.
