D-PHY latency:
The MIPI D-PHY RX core latency is the time from the start-of-transmission (SoT) pattern on
the serial lines to the activehs signal assertion on the PPI .The HS_SETTLE period contributes
significantly in the D-PHY latency calculation.
Tab l e 2 - 1 provides the latency numbers for various core configurations.
