CAL receives one functional clock (CAL_FLCK) from PRCM that is also used for the OCP ports. The configuration port (OCPC) operates at half the functional clock speed (clock enable signal used).
In addition, CAL receives one asynchronous clock for each PPI interface. This clock is generated from the bit clock received from the image sensor and converted into a byte clock (CAL_BYTECLKHS) by the connected CSI2 PHY.
CAL also provides the PWRSCP clock used to configure the CSI2 PHY. It is equal to the CAL functional clock divided by 4 (CAL_FLCK / 4) and is gated depending on the functional needs.
